Labkyl is a part of Nordic Climate Group (NCG), a group consisting of 60 refrigeration companies in Sweden. The companies that make up NCG are niche players, and many are specialists in their fields. By joining forces, the entire group gains access to broad expertise and can also implement sustainable solutions on a wide scale.

“Historically, the refrigeration industry has consisted of many small companies, and the great thing about this solution is that all companies can still operate as individual companies with local involvement in each location. But if cutting-edge expertise is needed, it is available within the group”, says Patrik Larsson, Technical Manager at NCG, and also Technical Manager and Business Development Manager at Labkyl.

Climate improvements through natural refrigerants

New regulations

Several parameters and climate directives have benefited their business concept in recent years, such as the F-gas Regulation and the REACH Regulation, both of which prohibit harmful refrigerants. By 2030, there will be no environmentally hazardous refrigerants that can serve current facilities. This means that large property owners want to replace the old ones, and demand for Labkyl's solution is increasing.

Labkyl specialises in heat pumps and cooling systems with natural refrigerants. Its customers currently include Vasakronan, AMF Fastigheter, Castellum, and Hufvudstaden. 

“Our speciality is using carbon dioxide as a refrigerant, which is somewhat unique. Conventional refrigerants have a significant environmental impact, both in terms of PFAS and the greenhouse effect. We eliminate that, while also saving energy. When used in large facilities, it makes a very big difference to the climate”, says Patrik Larsson. 

“We call our solution the DLE concept. Trends in society are really driving our market, and the directives only give us opportunities”, he continues. 

Labkyl decided to use carbon dioxide as a refrigerant back in 2005 and renewed that decision in 2015. The goal is to use 100% natural refrigerants in its facilities, and currently, the company is at around 99%. Patrik believes that few other refrigeration companies are above 50% today.

Using Web Port and IWMAC for development

To achieve greater efficiency from heat pumps and cooling systems, the company also offers control, monitoring, and supervision of technical equipment. For a long time, Web Port has been used as a platform for managing buildings, in combination with IWMAC as an analysis tool for improving energy efficiency over time.

Web Port is now also part of Labkyl's proprietary control package, DLE Supervisor, and functions as a monitoring system at the facilities.

The DLE concept

The DLE concept consists of DLE units and DLE Supervisor. The DLE unit uses CO₂ (carbon dioxide) as a refrigerant to handle both heating and cooling production. DLE Supervisor is a proprietary, advanced platform with control functions that optimize energy flows for maximum efficiency and minimum energy consumption.

“Web Port is well established among property owners, so we use it as an entry point and then add energy monitoring modules on top. Sometimes there are customer requirements for other systems, but if we are free to choose, we prefer to go for a standardized total solution.“

Historically, Labkyl worked with various, loosely connected systems and did not have a proper overview or follow-up. Thanks to one of their major customers, ICA, which included IWMAC in its requirements specification, they came into contact with us at Kiona.

Right from the start, he found that it was quick and easy to install and integrate the systems at the customers' premises.

You send a drawing of the store or property, fill out a form, and then Kiona completes the integration and sends a computer that connects to the local router via a network cable.This makes integration incredibly smooth and there are no limitations in terms of hardware or server databases, which makes it very scalable.

"With new tools, we can optimize added value for customers in a cost-effective way. Ninety percent of our customers are not technicians, so it is positive that there is a lot of technology that they can use themselves, without any other knowledge."

Climate-friendly and energy-efficient solutions

Labkyl views the real estate industry as a growing market, where developments are moving quickly to shift towards more climate-friendly and energy-efficient solutions.

"We would like to see Kiona develop tools even faster and incorporate features into the systems that match and support our work even further. We are happy to collaborate as testers.", concludes Patrik.
