Denmark’s supermarket refrigeration market is built around natural refrigerants, digital controls and close cooperation between equipment suppliers, contractors and retailers. Danish grocery groups were early adopters of CO₂ systems. Companies such as Advansor and Danfoss helped turn that technology into a practical commercial standard.
Salling Group, Coop Danmark, REMA 1000 and Lidl continue investing in refrigeration systems. These systems lower energy use, reduce food loss and recover heat for store operations. The companies leading this market are not simply selling cabinets.
They provide CO₂ packs, monitoring platforms, installation services and retail equipment. Together, these shape how Danish supermarkets manage cooling, heating and energy performance.

Why Denmark Matters
Denmark is one of Europe’s most influential supermarket refrigeration markets. It combines strong domestic engineering with retailers willing to test new technology.
The country moved early towards CO₂ refrigeration as grocery groups looked for alternatives to high-global-warming-potential refrigerants. Danish suppliers then developed systems that went beyond cooling alone.
Modern installations increasingly combine refrigeration, heat recovery, store heating and digital performance monitoring.
Salling Group operates Netto, føtex and Bilka. It has worked with Danfoss on sustainable refrigeration since the 1980s. More recently, the companies expanded that relationship through digital monitoring and food-loss prevention using the Alsense platform.
Denmark also shows how supermarkets can become local heat suppliers. Danfoss documented a SuperBrugsen store in Augustenborg that reused 95% of the excess heat generated by its refrigeration system. Surplus heat was sent into the local district-heating network.
That combination of CO₂ technology, digital controls and heat recovery gives Denmark a distinct place within Europe’s food-retail refrigeration sector.
1. Advansor
- Founded: 2006
- Headquarters: Aarhus, Denmark
- FY Revenue: Private
- Core role: Transcritical CO₂ refrigeration systems
Advansor is one of Denmark’s most important commercial refrigeration manufacturers. It is a recognised specialist in transcritical CO₂ technology.
What it supplies
The company designs factory-built refrigeration packs. A single CO₂ system can provide refrigeration, freezing, air conditioning and heating. This integrated approach is especially relevant for supermarkets that want to reduce separate heating equipment, recover waste heat and lower total building energy use.
Documented Danish projects
Advansor has direct, documented Danish food-retail references. Its project for ALDI Denmark at Rådhuspladsen in Aarhus used a low-noise ValuePack CO₂ system. SA-AL Køleteknik was named as the contractor.
The project replaced high-GWP refrigeration with R744. It was designed for a densely populated urban location where equipment noise and available floor space were important constraints.
The company has also supplied a combined cooling and heating solution for a Danish Netto store. These projects confirm that Advansor’s role in Denmark is not limited to exporting refrigeration technology. Its systems are used within the domestic supermarket market.
Why it matters to supermarket buyers
Advansor’s competitive strength lies in producing complete CO₂ packs that arrive factory tested and ready for installation. This can reduce site work and improve commissioning consistency. It also gives retailers a clearer route to combining refrigeration with heat recovery.
2. SA-AL Køleteknik
- Founded: 1994
- Headquarters: Aarhus area, Denmark
- FY Revenue: Private
- Core role: Refrigeration installation and nationwide service
SA-AL Køleteknik represents the contracting and field-service side of Denmark’s supermarket refrigeration market.
What it does
The company installs, commissions and maintains commercial refrigeration systems. These include transcritical CO₂ technology, heat pumps and energy-optimisation equipment. It operates from locations including Aarhus, Egå, Ringsted and Kolding, giving it coverage across Denmark.
Nordic Climate Group identifies supermarkets as one of SA-AL’s principal customer segments.
SA-AL is directly linked to verified Danish supermarket projects. Advansor named the company as the contractor for its ALDI Denmark CO₂ installation in Aarhus. That role included the practical work needed to put the system into service within a constrained city-centre location.
Why it matters to supermarket buyers
For grocery retailers, the installer is often as important as the equipment manufacturer. Poor commissioning, delayed repairs or limited service coverage can increase energy use and expose stores to product losses.
SA-AL’s value therefore comes from its ability to connect manufacturers, control systems and supermarket operations. Its expertise in CO₂, commercial refrigeration, energy optimisation and service makes it one of the most operationally relevant companies in Denmark’s food-retail cooling sector.
3. Danfoss
- Founded: 1933
- Headquarters: Nordborg, Denmark

What it supplies
The company supplies these technologies:
- Electronic expansion valves
- Pack controllers
- Sensors
- Drives
- Cloud-based monitoring platforms
They manage refrigerant flow, track temperatures and optimise compressor performance. They also alert retailers when equipment begins operating outside normal conditions.
Documented Danish projects
Its Danish supermarket role is directly documented through Salling Group. In 2023, Salling Group, Danfoss and Microsoft announced a collaboration using Danfoss Alsense to track refrigeration performance. The collaboration supports preventative maintenance and reduces energy use and food loss across Danish stores.
Danfoss also has a long-standing connection with Salling Group’s transition towards sustainable cooling. The companies say their cooperation dates back to the 1980s, including the adoption of CO₂ and other lower-GWP refrigeration technologies.
The company’s influence extends into heat recovery. At SuperBrugsen Augustenborg, Danfoss technology helped reuse refrigeration heat for store heating, hot water and the local district-heating system.
Why it matters to supermarket buyers
Danfoss belongs in Denmark’s Top 5 because digital controls are now central to supermarket refrigeration performance. Hardware can keep food cold. Controls determine how efficiently the complete system operates.
