Refrigeration and freezing

<p>Today, most cooling systems are equipped with heat recovery. Heat recovery refers to capturing and reusing waste heat that would otherwise be lost to the environment. After the primary function of the cooling (or heating) capacity has been performed, the excess heat can be reused to either improve the efficiency of the heat exchange process or used elsewhere.</p>



<p>For example, by taking care of the cooling systems' heat recovery, the excess energy can heat the store and hot water instead of being cooled on the roof. This process will reduce the need to buy electricity from the grid and provide a better operating economy. The savings in energy costs can be as much as 30% when switching to carbon dioxide refrigerant.&nbsp;</p>



<h2 class="wp-block-heading" id="h-improved-energy-efficiency">Improved energy efficiency </h2>



<p>Understanding heat recovery and regeneration is essential for improving energy efficiency and sustainability in various sectors. Implementing these techniques can lead to significant economic and environmental benefits. Unfortunately, many do not have good enough systems to notify them or override their heat regenerator if a need elsewhere in the building appears.&nbsp;</p>

Want to try IWMAC for your cooling systems?

<p>Tired of sweating through the summer? When scorching summer temperatures set in, you're not the only one struggling to make it through the day. The hotter the weather, the harder your refrigeration system (and air conditioning system) must work, increasing the risk of equipment breakdowns.</p>



<p>These systems are essential for maintaining the quality and safety of perishable goods, but the heat can push them to their limits.</p>



<p><strong>On average, three times as many alarms go off during the summer</strong>, and the high temperatures make it crucial to maintain consistent product quality, prevent temperature fluctuations, and avoid ingredient spoilage.</p>



<h2 class="wp-block-heading" id="h-beat-the-heat-with-proper-maintenance">Beat the heat with proper maintenance</h2>



<p>The maximum cooling load usually occurs during summer. This is because the heat places a substantial load on these systems, compelling them to work harder and longer to maintain optimal temperatures.</p>



<p>To fortify your refrigeration systems against the summer heat, proactive maintenance is paramount. Waiting until the hot conditions trigger an unexpected breakdown is a costly gamble. Instead, prioritizing regular maintenance before the onset of summer ensures that your equipment is in optimal condition to weather the seasonal demands.</p>





<p>Of course, proper servicing is best left to the professionals. Don't have a maintenance schedule yet? See why you should – and <a href="https://kiona.com/our-partners" target="_blank" rel="noreferrer noopener">get help from one of our Certified Partners near you.</a></p>





<h2 class="wp-block-heading" id="h-beware-of-product-quality-invest-in-monitoring">Beware of product quality: invest in monitoring</h2>



<p>Even on the year's hottest day, you must maintain consistent product quality, prevent temperature fluctuations, and avoid ingredient spoilage. Modern building- and monitoring systems can alert you and your staff immediately if something is wrong with your refrigeration units.</p>



<p>Customers with <a href="https://kiona.com/products/iwmac" target="_blank" rel="noreferrer noopener">IWMAC</a> receive a notification when an alarm is triggered. If the temperature – or whatever you want to measure – goes above or below the set limit value, the system automatically notifies you. This will help you minimize food loss since you have limited time to restore the appropriate temperature before it all must be thrown out.</p>



<p><em>Remember: this time frame can be even shorter with higher temperatures.</em></p>



<h2 class="wp-block-heading" id="h-more-small-things-that-can-help-keep-your-refrigeration-systems-in-tip-top-shape">More small things that can help keep your refrigeration systems in tip-top shape</h2>



<p>Don't forget that seemingly small adjustments can make a big impact. Simple practices, such as keeping refrigerator and freezer doors closed and ensuring proper sealing, play a big role in conserving energy and maintaining consistent temperatures.&nbsp;</p>



<p>And<strong> beware of systems working against each other</strong>—high humidity conditions can impact air-cooled refrigeration systems just as much as high temperatures. Coordinate the ventilation and refrigeration systems to <em>complement </em>rather than work against each other.</p>

<p>Refrigeration systems often have a critical function. They ensure that technology doesn't overheat and that food and pharmaceuticals aren't destroyed. Preventative maintenance is essential to help avoid common problems and breakdowns and to keep your equipment working reliably for years to come.&nbsp;</p>



<p>The general recommendation is to <strong>service your refrigeration or freezer system twice a year</strong>. We always recommend using a professional cooling company.</p>





<p>In addition to having a professional crew and regular service agreement, there are several things you can do yourself to keep your equipment in the best possible condition all year round.</p>



<h2 class="wp-block-heading" id="h-refrigeration-maintenance-checklist-tasks-you-can-tackle-yourself">Refrigeration maintenance checklist: tasks you can tackle yourself</h2>



<p>Let's take a look at tasks you should perform on a daily or weekly basis:</p>



<figure class="wp-block-table"><table><tbody><tr><td><strong>Keep equipment clean:</strong></td><td>Timely cleaning safeguards against odors and mold, ensuring the safety and quality of stored items. Avoid using steel wool or harsh chemicals, such as bleach, as they can damage your appliance's finish.</td></tr><tr><td><strong>Monitor temperature settings:</strong></td><td>Regularly check and adjust temperature and defrost frequency settings. Make sure that the temperature isn't set lower than necessary; this will only make your system work harder.</td></tr><tr><td><strong>Defrost on schedule:</strong></td><td>Follow the manufacturer's recommendations for defrosting. More often than not, people are too eager. <a href="https://kiona.com/story/blog/defrosting-made-easy" target="_blank" rel="noreferrer noopener">Defrosting your unit</a> too often creates unnecessary strain on your refrigerator.</td></tr><tr><td><strong>Prevent overcrowding:</strong></td><td>Adequate airflow is essential for the unit to operate efficiently. A tightly packed refrigerator hampers air circulation, forcing the unit to work harder to maintain its set temperature.</td></tr><tr><td><strong>Maximize airflow around the unit:</strong></td><td>Ensure there's sufficient space around your refrigerator for proper airflow. Avoid blocking air intake and exhaust vents, as this can lead to increased energy consumption and premature system failure.</td></tr><tr><td><strong>Inspect and fix seals:</strong></td><td>Regularly inspect door gaskets for tears or looseness. Repair minor gasket leaks with silicone caulk and secure door hinges and latches. Perform this check monthly to maintain a tight seal.</td></tr></tbody></table></figure>

<h2 class="wp-block-heading" id="h-trust-the-professionals">Trust the professionals</h2>



<p>A service can involve several different tasks, depending on the size and complexity of the system. Even if you have pretty good knowledge, many jobs are best left to the professionals.</p>



<p><a href="https://kiona.com/our-partners" target="_blank" rel="noreferrer noopener">Our Certified Partners</a> are well-versed in cooling technology, and many offer both predefined service agreements and customized services according to your needs.</p>



<p>If you find it difficult to remember to book service at certain times, a<strong> service agreement</strong> can be the perfect solution. Many of our partners also have a 24-hour on-call service should anything unforeseen occur.</p>







<h2 class="wp-block-heading" id="h-why-you-need-a-maintenance-plan">Why you need a maintenance plan</h2>



<p>Most issues that affect your refrigeration system will make it work harder, leading to more repairs and higher electricity costs. An ignored problem can result in a costly breakdown when you can least afford it.&nbsp;</p>



<p>In addition to servicing, a professional company will be <strong>up to date</strong> on environmental requirements and new technology. They also often help <strong>improve the operation</strong> of cooling systems to reduce energy consumption. For example, refrigeration systems always generate heat. Why not reuse the heat and save energy?&nbsp;</p>



<p>It's always smart to have a professional regularly inspect your equipment for signs of trouble and prevent problems before they turn into breakdowns.</p>

Why you need a refrigeration maintenance schedule – and a daily task checklist

<p>Commercial refrigeration is a lifeline for many businesses, including restaurants, grocery stores, and pharmaceutical companies, among others. These systems work tirelessly – typically continuously – keeping products at optimal temperatures to preserve their quality and safety. However, like any other workhorse, they require regular care and maintenance to continue performing efficiently.&nbsp;</p>



<p>But even well-maintained systems can run into operational problems from time to time. Knowing the issues that might occur is critical to prevent them from escalating into serious ones.&nbsp;</p>



<p>Here are some common problems your commercial refrigeration or freezer units might run into:</p>



<h2 class="wp-block-heading" id="h-ice-buildup-in-the-refrigerator">Ice buildup in the refrigerator</h2>



<p>Ice buildup is one of the most common problems encountered in commercial refrigeration – but you shouldn't let it go too long before you take action. This usually occurs due to issues with the defrosting system, poor door seals, blocked vents, or doors left open for too long.&nbsp;&nbsp;&nbsp;</p>



<p>Excessive ice can block the inflow of cold air, forcing your refrigeration system to work harder and consume more energy. This can eventually lead to component failure.&nbsp;</p>



<p>Make sure to regularly inspect door seals and replace any faulty ones. Paying extra attention to these small details, coupled with <strong>the correct defrosting routine</strong>, can help prevent this issue.</p>





<h2 class="wp-block-heading" id="h-failure-to-maintain-temperature-levels">Failure to maintain temperature levels</h2>





<p>If your refrigeration system cannot maintain proper temperature levels, it is essential to <strong>check the unit's temperature setting</strong>. The inability to provide enough cooling may be due to dirty condenser and evaporator coils, a malfunctioning compressor or thermostat, incorrect temperature settings, dirty fans, or inadequate airflow inside the refrigerator.</p>



<p>Regular temperature monitoring and calibration can help ensure accurate temperature control. Even refrigerators with automatic temperature settings should be checked regularly.</p>





<h2 class="wp-block-heading" id="h-unfamiliar-noises">Unfamiliar noises</h2>



<p>Your refrigeration system should hum along quietly. If you start hearing unfamiliar noises – grinding, rattling, or buzzing – it's a clear signal that something is wrong. These noises could indicate an issue with the compressor, fan motor, or other internal components. Ignoring these sounds can lead to serious damage and costly repairs.</p>



<p>Always <strong>consult a professional technician</strong> if your system starts making unusual noises; it's rarely a sign of something good.</p>



<h2 class="wp-block-heading" id="h-a-sudden-increase-in-energy-usage">A sudden increase in energy usage</h2>



<p>A sudden spike in your energy bills could indicate that your refrigeration system isn't working efficiently. However, several factors could contribute to this, like dirty condenser coils, malfunctioning fans, outdated equipment, temperature fluctuations – or a combination.</p>



<p>No matter what issues you find or suspect, it's a good idea to regularly have a professional technician check and take care of your commercial refrigeration equipment.</p>

<p><a href="https://www.nrkyl.se/">NR Kyl AB</a>, a certified Kiona Partner, operates in Gothenburg and was founded in 2012. They aim to promote sound cooling technology with climate-wise refrigerants in grocery stores, restaurants, and buildings.</p>



<p>"We have service teams that carry out repairs and service on existing facilities and installers that build new facilities and rebuild when stores need to update and invest in more modern refrigeration systems," says Emil Sundgren, Service Manager at NR Kyl AB.</p>



<h2 class="wp-block-heading" id="h-avoiding-downtime-and-food-waste">Avoiding downtime and food waste</h2>



<p>Monitoring and measuring refrigeration systems is crucial to avoid refrigeration downtime and food waste. </p>



<p>"Alarms can go either to an alarm center or directly to us," says Emil. "We will then call the grocery store and give a recommendation on what they need to do.</p>





<p>When an alarm comes in from the alarm center, he assesses what needs to be done, writes service orders, and outsources the job to the refrigeration technician who is most suitable for the job. He is also responsible for planning the preventive maintenance of the stores' refrigeration systems.</p>



<h2 class="wp-block-heading" id="h-digital-surveillance">Digital surveillance</h2>



<p><a href="https://kiona.com/products/iwmac">The IWMAC system</a> is used to monitor connected grocery stores around the clock. Refrigeration technicians can easily prevent and adjust faults remotely by installing sensors and setting parameters for temperature, pressure, effect, and opening ratio.</p>



<p>"This allows us to provide a very high level of service to our customers and help them reduce food waste, unnecessary disruptions, and lower energy consumption," says Emil.</p>





<p>"Today, energy efficiency and optimization are essential for the customer to stay on top of. Each measurement provides information on how the counter, room, or fridge works; you don't have to be on-site to see it. This results in lower on-call costs because you can immediately see if action is needed or if it can wait. It also provides information on how to optimize consumption, saving both time and money."</p>



<h2 class="wp-block-heading" id="h-from-freezing-and-cooling-to-heating">From freezing and cooling to heating</h2>





<p>Another important part of IWMAC is <a href="https://kiona.com/products/iwmac/smart-functions">forecast control and heat recovery.</a> Through adjustments, grocery stores can harness the excess energy from refrigerated counters and convert it into heat.</p>



<p>"Most cooling systems are equipped with heat recovery. This means the energy can heat the store and hot water instead of being cooled on the roof. This reduces the need to buy electricity from the grid and provides a better operating economy." Emil says that as many as 75-80% of customers use the surplus energy from their cooling systems.</p>



<p>IWMAC also has functions for self-monitoring and HACCP food quality control.</p>



<p>"The establishment's owner is responsible for ensuring that the food the consumer purchases is safe. This means that you have to keep track of whether there are deviations from what is normal. With the help of digital monitoring, we can see the history and assess whether something is wrong," says Emil.</p>



<h2 class="wp-block-heading" id="h-customer-focus">Customer focus</h2>



<p>Emil believes that by knowing the customers' business and understanding their challenges, NR Kyl can offer tailored solutions and reliable service.</p>



<p>Older refrigeration systems can mean that it is more difficult to solve the problem and that refrigeration technicians must go out several times. The customer needs to understand why.</p>



<p>"It's a bit like an old car that can't be driven – one time, it's a faulty spark plug, and the next time, it could be a broken fan belt. Having digital monitoring means we can be proactive and work with preventive maintenance so that the customer gets safer and smoother operations."</p>



<figure class="wp-block-image size-full"><img src="https://kiona.com/app/uploads/2023/12/NR_Kyl_blog_700x400_x2.webp" alt="NR Kyl works with digital monitoring at a grocery store" class="wp-image-48412"/><figcaption class="wp-element-caption">NR Kyl works with digital monitoring at a grocery store. (Photo: www.nrkyl.se)</figcaption></figure>



<h2 class="wp-block-heading" id="h-dare-to-charge-for-knowledge">Dare to charge for knowledge</h2>



<p>It used to take a long time to fix faults in a refrigerated counter. Today, however, the refrigeration industry has other challenges, mainly the ability to recruit and retain competent staff.</p>



<p>"For the general public, the refrigeration sector is not as well-known as other professions such as electricians, plumbers, and painters. This creates a challenge in attracting talent and ensuring a stable workforce."</p>



<p>"Another challenge is the lack of training opportunities in refrigeration technology. The increasing demand for qualified personnel has led to competition for skills and increasing wage demands. That means we must have the courage to charge for the time spent."</p>





<p>He points out that the choice of refrigeration supplier is important. </p>



<p>"You must have the courage to make demands and choose someone with high competence and a good reputation within the trade community. Although many customers look at the price, the cheapest is rarely the best in the long run," he says.</p>



<p>Advising, monitoring, and recommending refrigeration systems has improved efficiency and reduced food waste for many customers. This has been made possible by NR Kyl's early embrace of new technology and its integration with advanced digital monitoring.</p>

Better efficiency and less food waste with digital monitoring of refrigerated counters

<p>"The refrigeration and cooling tech market is established, there are integrations, there is unity and openness in the technology, but there is no solution today that effectively connects and ties everything together."</p>



<p>We aim to bring a solution that does just that. Joacim Hindersson, Head of Business, believes that <a href="https://kiona.com/products/iwmac" target="_blank" rel="noreferrer noopener">our monitoring software, IWMAC</a>, is the missing piece of the puzzle.</p>



<p>"Enough with the fragmented solutions and disconnected systems. We're here to challenge the status quo in the market by looking at the whole picture and integrating all systems. It's time for the industry to step up and embrace true efficiency," says Joacim.</p>





<h2 class="wp-block-heading" id="h-simplicity-and-scalability-at-its-core">Simplicity and scalability at its core</h2>



<p>Hindersson emphasizes that the system caters to both small shops and large chain-owned supermarkets, as well as other large, complex buildings. The ability to adapt to different sizes and complexities sets it apart from other solutions.</p>



<p>And in a world driven by data, businesses need to make decisions based on reliable information.</p>



<p>"It's <strong>no longer enough</strong> to rely on guesswork or gut feeling. With IWMAC, we provide the tools and knowledge necessary to <strong>make data-driven decisions</strong> that maximize cost-effectiveness, minimize waste, and cut unnecessary expenses", Joacim explains.</p>



<p>Over 5,000 buildings in the Nordic region have already installed IWMAC. The system is <strong>used by service contractors</strong> to optimize systems so they can run as energy efficiently as possible.</p>



<h2 class="wp-block-heading" id="h-proven-reliability-for-service-partners-and-refrigeration-technicians">Proven reliability for service partners and refrigeration technicians</h2>



<p>But the solution doesn't just benefit businesses; it empowers service companies as well. One of the key factors behind IWMAC's success is the collaboration with skilled partners. These partners bring their expertise and in-depth knowledge of processes and customer needs, <strong>enabling seamless integration into existing systems</strong>.</p>



<p>Instead of a reactive service model, partners can identify product defects and process errors before they cause significant issues. This saves money for the customer and allows partners to build up their service business by delivering ongoing monitoring and follow-up.</p>

Do you have cooling systems that need monitoring, control, and follow-up?

<p>In every grocery store, beyond the endless aisles of products and bustling shoppers, there's a well-orchestrated system in place to ensure that the food you purchase is safe and of the highest quality.</p>



<p>Food safety is not just a matter of legal compliance; it is a fundamental responsibility for anyone running a store. And almost as importantly – your customers need to be happy.</p>



<h2 class="wp-block-heading" id="h-internal-controls-the-devil-lies-in-the-details">Internal controls: The devil lies in the details</h2>





<p>In a supermarket, every step requires attention to detail, from receiving deliveries to stock rotation and waste management.</p>



<p><strong>Internal controls</strong> are the routines businesses have in place to comply with food safety regulations and to document that these are followed. For instance, the receipt of raw ingredients<strong> must be properly documented.</strong> The second you receive the goods, you are responsible for ensuring they remain at the right quality.</p>





<h2 class="wp-block-heading" id="h-temperature-monitoring-the-biggest-pitfall">Temperature monitoring – the biggest pitfall</h2>



<p>When it comes to storage, ingredients <strong>must be stored at temperatures that prevent bacterial growth</strong>. That makes refrigeration and freezing one of the cornerstones of food safety.</p>



<p>Maintaining appropriate temperatures not only prevents bacterial growth but also extends the shelf life of perishable goods. But in the fight against microorganisms, temperatures are typically the biggest pitfall.</p>



<p>If you're running a convenience store, you have to <strong>document that you're monitoring the temperature chain</strong> and that anomalies are being dealt with. The best way is to have automatic monitoring and digital documentation procedures.</p>





<h2 class="wp-block-heading" id="h-hygiene-is-always-important">Hygiene is always important</h2>



<p>Pandemic or not, hygiene and cleaning are always important.</p>



<p>Maintaining impeccable hygiene standards is paramount in preventing the spread of bacteria. Regular cleaning and sanitization of surfaces, equipment, and utensils are essential to <strong>eliminate potential sources of contamination</strong>.</p>



<p><em>Remember: Disposable gloves give a sense of false security – they do not provide enough protection alone. You still need to wash your hands properly, and you can still spread infections even if you wear gloves. Make sure you have documented routines in place for washing fabrics, equipment, and hands.</em></p>



<h2 class="wp-block-heading" id="h-little-things-add-up-to-creating-a-good-customer-experience">Little things add up to creating a good customer experience</h2>



<p>Have you ever been in a store where you just didn’t feel quite right – without being able to put your finger on precisely why? When it comes to order, it is largely the subconscious that picks up on visual signals.&nbsp;&nbsp;</p>



<p>Are the products positioned with the labels facing the right way? Are there crumbs in the bread-slicing machine? These are small things individually, but <em>together,</em> they help to create the customer experience. If you have order, people will feel welcome.&nbsp;&nbsp;&nbsp;</p>



<p>But no matter how important clean floors and tidy shelves are, you should never forget that people are influenced by other people. Action is also interaction. So, the best thing you can do to make people happy and smile – <strong>is to smile at them first.</strong></p>

The supermarket routines that bring order – and satisfied customers

<p>When you throw food out, it's not just the food that goes to waste. The farmer's effort, the fuel that has been used to transport the goods, and respect for the fact that we have food on the table shouldn't be taken for granted.</p>



<p>Globally, around 14 % of food produced is lost between harvest and retail, while an estimated 17 % of&nbsp;<a href="https://www.un.org/en/observances/end-food-waste-day/" target="_blank" rel="noreferrer noopener">global food production</a>&nbsp;is wasted.</p>



<h2 class="wp-block-heading" id="h-supermarkets-are-big-energy-spenders">Supermarkets are big energy spenders</h2>





<p>In addition to large volumes of food getting lost somewhere in the supply chain, supermarkets are one of the most energy-intensive sectors among commercial buildings. The primary reason for this high energy consumption is refrigeration, which can account for more than half of all the energy used.</p>



<p>Food that is lost and wasted accounts for&nbsp;<a href="https://www.un.org/en/observances/end-food-waste-day/" target="_blank" rel="noreferrer noopener">38 % of total energy usage</a>&nbsp;in the global food system. Meaning that energy efficiency and food waste are highly intertwined.</p>





<p>It's difficult to address the whole value chain; we can't solve everything at once. But we can do something about the food that is lost due to improper storage or failing refrigeration and freezing systems. For some stores,&nbsp;<a href="https://kiona.com/products/iwmac/wireless/" target="_blank" rel="noreferrer noopener">wireless temperature monitoring</a>&nbsp;could be the route to avoid food waste.</p>



<h2 class="wp-block-heading" id="h-benefits-of-wireless-temperature-monitoring"><strong>Benefits of wireless temperature monitoring</strong></h2>



<p>A wireless solution is a good replacement for cabled equipment and is a useful way to cut costs, enhance flexibility and get faster, less invasive installations.</p>



<figure class="wp-block-image size-full"><img src="https://kiona.com/app/uploads/2023/03/Step-2.png" alt="Wireless sensors" class="wp-image-33617"/><figcaption class="wp-element-caption">The wireless sensors fit just about everywhere - no matter what kind of equipment you already have.</figcaption></figure>



<p>Wireless devices are versatile and can be used for more than you might think. Here are 3 benefits you should know about:</p>



<h3 class="wp-block-heading" id="h-reduces-the-risk-of-product-loss">Reduces the risk of product loss</h3>



<ul>
<li>The temperature sensors communicate with our servers, so you get an SMS warning you of deviations if the temperature rises above or drops below set limits. This way, you can avert loss and gain greater control over the food you sell.</li>
</ul>



<h3 class="wp-block-heading" id="h-quick-and-simple-installation"><strong>Quick and simple installation</strong></h3>



<ul>
<li>You can fit the wireless sensors precisely where something needs measuring, and installation is so simple you can do it yourself. To begin with, we set the limit values for you. Later on, you can log in and change them as you wish.</li>
</ul>



<h3 class="wp-block-heading" id="h-versatile">Versatile</h3>



<ul>
<li>Many kiosks, small shops, canteens, and gas stations opt for wireless monitoring. But did you know that they are also used in car washes, boats, and public transport? Measure moisture or temperature, with plenty of fastening options and long battery life.</li>
</ul>



<p>Because the system is wireless, the sensors can be used in many different places. In fact, you can connect up to 60 sensors to one gateway. Simple, fast, and affordable.</p>

<p><em>Here are some handy everyday hints for all those food rescuers out there:  &nbsp;</em></p>



<ol>
<li><em>Ugly fruit or weird carrot? Cut away the blemishes, and buy fruit that doesn't meet the cosmetic standard. They taste the same.</em></li>



<li><em>Rummage a little in the fridge when you refill it and put the oldest item at the front. Make sure the refrigerator is at the right temperature.</em></li>



<li><em>Best before, but not bad after! The look, smell, and taste test is often a good clue as to whether the food is safe or not.</em></li>

NordDisk has known about <a href="https://kiona.com/products/iwmac/">IWMAC, our SCADA for cooling and refrigeration</a>, since the dawn of time and has used the system in supermarkets since the early 2000s. As a total supplier of services and equipment within refrigeration, freezing, and air conditioning, they tailor solutions and take on projects from A to Z.</p>





<p>Therefore, they are well aware of what is happening in the market.</p>



<p>– We wanted to become partners to develop further in the field of energy saving and deliver easier monitoring, notification, and control through SCADA systems. Since then, we have delivered many smart solutions for managing complete systems within buildings and larger stores. It has been very successful, Korsnes explains.</p>



<p>After installing and delivering the system solution, <a href="https://www.norddisk.no/" target="_blank" rel="noreferrer noopener">NordDisk</a> continues to "tune" the system to perform in the best possible way. With the help of IWMAC, they can immediately catch unnecessary errors and excessive energy consumption linked to ventilation, cooling, and heat recovery.</p>



<p>That makes it possible to follow up operations according to the KPIs that have been set and to deliver cost-effective facilities that also work in an energy-efficient manner.</p>



<h2 id="h-refrigeration-and-cooling-solutions-that-save-energy">Refrigeration and cooling solutions that save energy</h2>



<p>Furthermore, Korsnes points out that the focus and potential for energy saving when it comes to refrigerants is increasing, but that as an industry, they still have a way to go. It also depends on the suppliers being willing to create the right solution.</p>



<p>– The overall picture of cooling, ventilation, and power-saving measures, which we can easily control via the web, is important in this work. It allows us to reuse much of the energy we have used in the system and control pressure as needed on the cooling and air conditioning systems, he says.</p>





<p>He thinks they will have a steep curve for another three to five years before the industry has replaced most of the old technology. The climate industry is still lagging behind, so this market will take over as a focus area in two to three years.</p>



<p>Constantly developing and delivering better, more climate-friendly solutions is a must and makes it possible to adapt to the market. Something that only becomes more and more important.</p>



<h2 id="h-it-pays-to-be-partners">It pays to be partners</h2>



<p>With a focus on service, technology, and close customer follow-up, NordDisk has hands-on experience in precisely being capable of change.</p>



<p>– We see it as one of our strengths that we have a short service path between suppliers, customers, and partners. This means that we can turn around quickly to meet your wishes and requirements. With close cooperation, we have managed to lift ourselves up compared to our competitors. We are therefore very grateful for the Kiona partnership, Korsnes concludes.</p>



<p>The collaboration between service providers, software, and hardware vendors enables us to put our heads together to deliver the best possible solution for customers. The focus on close collaboration produces clear results, proving this is the right way.</p>

Make sure your produce always stays fresh

<p>Temperature control is mostly about ensuring food safety, and we have strict requirements for fridges and freezers in Europe. The main rules are that</p>



<ol type="1"><li>perishable foodstuffs must be stored at 4 °C or lower</li><li>the cold chain must be uninterrupted</li><li>the temperature of freezers should be -18 °C or lower</li></ol>



<p>But even in the good fight against microorganisms, it's foolish to use more energy than necessary. So it's worth looking closely at the product: What is the specified storage method? If you have several products that can withstand temperatures higher than 4 °C, you can store them together in a separate cabinet. It's a waste of energy to keep them at a lower temperature than necessary.</p>



<h2 id="h-how-cold-is-too-cold-for-your-refrigeration-units"><strong>How cold is too cold for your refrigeration units?</strong></h2>





<p>Of course, when it comes to your freezer, it's not like -36 °C is twice as good as -18 °C. Anything below 22 °C is, in practice, the equivalent of throwing energy right out of the window. So it's best to keep the temperature in the freezer within this 4-degree range. The temperature will fluctuate, but if you have IWMAC monitoring, you'll get reports with temperature logs every 24 hours. That way, you can quickly check if products are in danger – or if there is energy to be saved.</p>



<h2><strong>Cool facts about temperatures</strong></h2>



<p>At Kiona, we often visit new customers at supermarkets to supply training. Once accurate temperature monitoring is in place, many have a real lightbulb moment. Here are the most common experiences, summarised in three practical temperature tips.</p>



<h3><strong>1. Close the door to the freezer or refrigerated room when restocking</strong></h3>



<p>Heat exchange happens faster than you think. Ensure that the refrigerated/freezer room door does not leak, and never leave it open while restocking items. Otherwise, warm air and moisture can sneak in, and ice forms.</p>



<h3><strong>2. Don't let the ventilation work against you</strong></h3>



<p>Fridges and freezers are seriously affected by the temperature and air humidity elsewhere in the store. When summer finally arrives, this is especially important to look at and address. If it's 20 °C in the store with 40% humidity – as it is in winter – you'll have around a 55% load on the refrigerated counter and freezer. However, if it is 20 °C with 60% humidity, the load will quickly become 75%. And that's something you need to keep in mind.</p>



<blockquote class="wp-block-quote"><p>I have even seen ventilation systems blowing 27 °C warm and humid summer air into the store. Then we're talking a load of over 100 percent. It's a complete waste when two systems are fighting against each other.</p><cite><em>Viktor Bardun, Sales Coordinator, Kiona</em></cite></blockquote>



<p>Want control of your uptime? <a href="https://kiona.com/products/iwmac/">Let your ventilation, cooling, and heating work together!</a></p>



<h3><strong>3. Don't leave the door of the store open</strong> </h3>



<p>And last but by no means least: We understand that it can be tempting to leave the store's door open in the summer. Many people do, but it's not good for your refrigeration and freezer system. Better to have the store a little cold and close the door. This gives your food a safer environment and reduces your fridge's freeze burden – and your electricity bill.</p>

How to store food - and save energy

Learn about monitoring energy consumption and temperatures

<p>The <a href="https://www.seedvault.no/" target="_blank" rel="noreferrer noopener">Svalbard Global Seed Vault</a> was opened in 2008 and is now home to over one million seed samples. Some people have compared it to Noah's ark. Others have called it a frozen Garden of Eden. The biblical allegories suggest the seriousness of the issue.</p>



<p>"This is not our biggest assignment, but it may well be our most important. It's with a certain sense of awe that we look after what may come to look after all of us eventually," says Jostein Markussen of Kiona.</p>



<h2 id="h-with-eyes-on-mother-earth-s-backup-monitoring"><strong>With eyes on mother earth's backup – monitoring</strong></h2>



<p>It all started when the company Kuldeteknisk (now PTG), a Kiona-certified partner, won the tender to supply the refrigeration plant to total contractor Hæhre. They knew who they wanted to bring along with them as a subcontractor.</p>



<p>"We do a lot of good things with Kiona. They deliver reliable solutions and are flexible, and we work well together. If we need anything, they solve it for us. That's how it was in this case, too," says Martin Corneliussen, project manager at PTG.</p>



<p>While PTG supplies the equipment, Kiona is responsible for monitoring the technical equipment, such as the dehumidification system and CO2 machine, using the SCADA system IWMAC. They're also responsible for monitoring energy consumption and temperatures – from the main door into the innermost and holiest storage areas.&nbsp;</p>



<h2><strong>Overview – and remote control</strong></h2>



<p>Thanks to detailed system images, the cooling contractor can monitor that everything is working correctly. "That's the key to this project," says Corneliussen.&nbsp;</p>



<p>"All the aspects here are important, but without monitoring, we wouldn't be able to maintain control of what's happening. That's vital for Statsbygg, the Norwegian government's building commissioner. They've completed major modifications and are very keen on maintaining a complete overview," he continues.</p>





<figure class="wp-block-image size-large"><img src="https://kiona.com/app/uploads/2022/04/svalbard-seedvault-alamy-P2PPYH-1440x958-1-1024x682.jpg" alt="Inside the Svalbard Global Seed Vault" class="wp-image-1460"/><figcaption>Photo: Svalbard Global Seed Vault (Seed Bank) in Svalbard, Norway. Photo by Hemis / Alamy</figcaption></figure>



<p>At the same time, it's not just about monitoring because what if something needs to be changed? Markussen at Kiona explains that the overview is only half the story.&nbsp;</p>



<p>"It's one thing always to have a clear picture of what's happening, but you also need control. Our system allows service partners to remotely control and customize the system from anywhere in the world. So they don't need to travel to Svalbard to make changes."&nbsp;</p>





<h2><strong>The value of perfect temperature</strong></h2>



<p>There are several reasons why Platåberget mountain on Svalbard was chosen. One of them is that the mountain is frozen.</p>



<p>"In other words, what is stored there is not just artificially refrigerated. That provides an extra level of security as a fail-safe. If the human systems failed, the seeds would still stay cold," says Corneliussen at PTG.</p>



<p>But the correct temperature is also about predictability and stability. And the site owner's instructions are clear: The temperature must be -18 °C. No more, no less.</p>



<p>"It is our job to achieve that precise temperature," he explains and concludes:</p>



<p>"And using IWMAC, we can both ensure and document that we can do just that."</p>

Want to get control over your defrosting procedures?

<p>Regular defrosting is essential for some counters and cabinets to ensure optimal function. If there's too much ice in your fridge and freezer, it can block the inflow of cold air. This either leads to the unit working harder than necessary or the temperature becoming too high. Either way, it's bad news.</p>



<h2><strong>Chill a little</strong></h2>





<p>So you probably think that you defrost too infrequently? Of course, that may be the case – there are huge differences between freezer cabinets and refrigerated rooms. But in reality, you're probably a little too eager! The most common mistake we see is that people defrost too often. And there's a simple explanation: While older counters and cabinets quickly began to complain if you didn't defrost them 2 or 3 times a day, many modern fridges and freezers are far more forgiving.</p>



<p>So if you've recently switched your refrigerant to a modern, CO<sub>2</sub>-based one, you'll also need to change your settings.</p>



<p>But won't it make a difference if I do it more often, you may be thinking? Yes, a little – because defrosting uses more power. If you do it more often than necessary, you're just wasting energy. And we don't want that.</p>



<h2><strong>Find the right defrosting routine</strong></h2>



<p>The right defrosting routine depends on what kind of equipment you have – so make sure you're familiar with it. In addition, many related factors affect how often you need to remove the ice from your fridge and freezer.</p>



<p>How often is the room used? What are the room temperature and humidity otherwise? For example, more ice will also form if you have a dairy storage room where people are walking in and out all the time and letting in a lot of moist and warm air. In that case, of course, you need to defrost more often.</p>



<h2><strong>Get control and an overview</strong></h2>



<p>But how can you know when the time has come to defrost? And how do you know if your actions are having an effect – did that defrost program really help? Today you can get excellent help from smart sensors, which can detect if the airflow is sufficient and measure the temperature at which the ice forms.</p>



<p>If you have <a href="https://kiona.com/products/iwmac/">IWMAC</a>, it's easy to track whether the electric heating elements are doing their job – or if you need to step in and defrost manually. Monitor whether the temperature increases when the "toaster" defrosts. If it doesn't, it won't cause the ice to melt.</p>



<p>Add <em><a href="https://kiona.com/products/iwmac/smart-functions/">Smart Functions</a></em> to your IWMAC, you can easily simulate whether or not you're defrosting too often. You'll also get all deviation indications sent to you directly, so you can optimize your energy consumption. It's far cheaper than walking around and checking the sensors manually – or getting others to do it.</p>



<h2 id="h-keep-an-eye-on-the-defrost-time"><strong>Keep an eye on the defrost time</strong></h2>





<p>If you're responsible for refrigerated counters and freezer cabinets, you're probably as tired of the "Frozen" problem as the parents of small kids are. In pure frustration, turning up the stop temperature is easy, believing it will make short work of ice. But if you want to "let it go," you should set the stop temperature close to the product temperature.</p>



<p>And if your freezer room is fully defrosted after 10 minutes, setting the defrost time to 30 minutes makes no sense. The goal is to melt the ice – not use the unit to heat the freezer room. It's a waste of energy.</p>

Defrosting made easy - take control of the ice

Take control of your technical systems

<p>Among other things, we're talking about our food. For many store managers, the worry will always be there, like a buzzing noise in the background. A voice that never stops whispering: What if something goes wrong? What if it happens tonight?&nbsp;</p>



<p>At Kiona, we're working to silence that voice — so you can feel more reassured. But not just for that reason. We view it as our social mission to help safeguard these resources. It's about the essential foods intended for people's homes and maintaining sufficient quality. And when we're able to protect that, we reduce both food waste and our climate impact.&nbsp;</p>



<h2 class="wp-block-heading" id="h-guardians-of-the-ark-nbsp">Guardians of the Ark&nbsp;</h2>



<p>Food isn't just stored in the shops. That's why we need to keep our eye on the ball throughout the value chain. Today we have both systems and people monitoring central warehouses throughout the continent. We ensure that food is never exposed to the wrong temperature – and we prevent waste wherever it can occur.&nbsp;&nbsp;</p>





<p>And it doesn't stop with food. Medicine warehouses also rely on uncompromising monitoring to ensure vital medicines are not wasted. In fact, many medicines are far more temperature-sensitive than even food. Socially critical drugs require very specific storage conditions everywhere, from pharmacies in hospitals to large medicine warehouses.&nbsp;&nbsp;</p>



<p>And in Svalbard, 1300 kilometers north of the polar circle, perhaps the holiest is located: <a href="https://www.regjeringen.no/en/topics/food-fisheries-and-agriculture/svalbard-global-seed-vault/id462220/">The Global Seed Bank</a>. The ark itself. "The doomsday vault." It is part of the last shield we hold in our hands there. We're pretty proud of that.&nbsp;</p>



<h2 class="wp-block-heading">Remote control in a time of crisis&nbsp;</h2>



<p>But the greatest non-conformance of all is this: The earth's temperature is all wrong. The alarm has gone off. Here we may not be able to do quite as much, but we can do something. We can arrange for you to control your building's energy consumption wherever you are. We need to end waste. Energy thieves need to be stopped. In addition, in times of crisis, the operations manager can put the building into 'hibernation.'&nbsp;&nbsp;</p>



<p>That option to control systems remotely is essential. We have systems in place in both nursing homes and care homes. If a contractor or service partner is not allowed to travel there when something fails, they can deal with the non-conformance from their current location. And if they need advice, they may be among those who can get it from our <a href="https://kiona.com/products/iwmac/alarmmonitoring-24-7/">alarm centre</a>.&nbsp;&nbsp;</p>



<p>Because there are heroes around who don't wear a cape or uniform. The people who monitor all these stocks of food and medicine – and even more secret things – 24 hours a day. Their job is to let you know the second something goes wrong.&nbsp;&nbsp;</p>



<p>Together with our systems, they are the safety net for all those critical resources.&nbsp;</p>

Matsentralen Trøndelag

In Norway, we throw away 385,000 tonnes of food a year. That food should first go to someone who needs it, but it has also cost the environment a lot to produce it in the first place. I had wanted digital monitoring of the temperature, so I don’t have to remember to write it down manually. It is much more comfortable, and besides, it is reassuring to know that I am notified if something goes wrong. There has been a strong spirit of hard work, and Kiona has been in good company. I am very grateful that people stand up for us.

We are concerned about food safety and always follow the Food Safety Authority's guidelines. This contribution from Kiona makes it even easier to take care of the food we store.

Manager, Matsentralen Trøndelag

<h2 class="wp-block-heading" id="h-giving-food-people-and-the-environment-a-second-chance">Giving food, people, and the environment a second chance</h2>



<p>Every single month, <a href="https://www.matsentralen.no/matsentralene/trondelag" target="_blank" rel="noreferrer noopener">Matsentralen</a> distributes 40,000 meals to non-profit organizations. The least we can do is give back some extra food security.</p>



<p>Matsentralen is a network of eight food centers that facilitate the redistribution of surplus food from the food industry to non-profit organizations that help the disadvantaged. The goal is to create a sustainable food system.</p>



<p>The food center opened in Trondheim in 2018. Together with its donors and recipients, it contributes to 7 of the UN's 17 sustainability goals – the world's joint work plan to eradicate poverty, fight inequality, and stop climate change by 2030. We at Kiona are proud to contribute in our way, with what we do best. That is why we support Matsentralen with a free IWMAC system.</p>



<p>Through their work, they help the food industry reduce food waste and enable non-profit organizations to help people in difficult life situations.</p>



<p>The collaboration with Kiona consists of the SCADA system IWMAC, which provides digital monitoring of the temperature in the cloud solution. This gives the food center a better overview of the food they take care of and prevent further loss of goods. The facility is monitored, and managers are notified if deviations occur. In this way, they have a complete overview of the refrigeration systems – and can override them from anywhere.</p>
