Germany’s supermarket refrigeration sector has become one of the world’s most important testing grounds for low-emission cooling technologies. Three factors have accelerated investment in natural refrigerants and energy-saving systems:
- Tight European environmental regulations
- Generous government incentives
- The dominance of highly efficient discount retailers
The country is also experiencing a period of major industry consolidation. Acquisitions such as Epta’s takeover of HAUSER and Haier Smart Home’s purchase of Carrier Commercial Refrigeration are reshaping the competitive landscape.
At the same time, retailers including ALDI, Lidl, Edeka and REWE are investing heavily in refrigeration systems. They reduce operating costs and support long-term decarbonisation targets.

Why Germany Matters
Germany is not simply another large grocery market. It has become one of the world’s most demanding environments for refrigeration technology.
The country’s discount model is led by ALDI and Lidl. It relies on highly standardised store formats and exceptionally tight operating margins.
A refrigeration technology may prove successful across thousands of German discount stores. It often then becomes the blueprint for international rollouts, including stores in the United States and other European markets.
1. Epta Deutschland and HAUSER
- Headquarters: Germany and Austria operations across the DACH region
- FY Revenue: More than €2 billion combined group revenue
The biggest development in European supermarket refrigeration came in February 2026. Epta completed its acquisition of Austrian refrigeration manufacturer HAUSER.
The deal created one of Europe’s largest commercial refrigeration groups. It combines Epta’s engineering capabilities with HAUSER’s strong market position across Germany, Austria and Switzerland.
For German supermarkets, the enlarged group has become a major supplier of refrigerated cabinets, integrated systems and energy-efficient store solutions.
2. Carrier Commercial Refrigeration Germany (A Haier Company)
- Headquarters: Mainz-Kostheim, Germany operations
- FY Revenue: Private
Carrier Commercial Refrigeration entered a new chapter in late 2024. Haier Smart Home completed its $775 million acquisition of the business.
The acquisition included manufacturing operations, engineering capabilities and one of Europe’s largest refrigeration service networks.
For German retailers, the company remains a major supplier of CO₂ technologies and service support. It also benefits from Haier’s global technology resources.
3. Arneg Germany
- Headquarters: Germany operations
- FY Revenue: Private
Arneg has built a significant presence in Germany through refrigerated display cabinets and integrated refrigeration solutions.
The company serves supermarket operators seeking lower-emission systems and improved energy efficiency. Its broad product range has made it a regular supplier to large food retailers and independent grocery groups.
4. AHT Cooling Systems Germany
- Headquarters: Germany operations
- FY Revenue: Private
AHT has become one of Europe’s leading suppliers of plug-in refrigeration and freezer systems.
Discount retailers widely use its self-contained units. They need less complex installation and have lower maintenance costs. Propane-based R290 systems remain central to the company’s product strategy.
5. TEKO Gesellschaft für Kältetechnik
- Headquarters: Germany
- FY Revenue: Private
TEKO is one of Germany’s most important refrigeration engineering companies. It is a specialist in transcritical CO₂ systems.
The company has developed advanced technologies such as parallel compression and ejector systems. They improve the efficiency of CO₂ refrigeration during warmer weather.
Its expertise has made it a preferred supplier for retailers seeking highly efficient natural refrigerant solutions.
6. ENGIE Refrigeration
- Headquarters: Lindau, Germany
- FY Revenue: Private
ENGIE Refrigeration focuses on industrial and commercial cooling systems. It has a significant presence in food logistics and distribution infrastructure.
Its technologies support supermarkets and food manufacturers that require large-scale refrigeration and temperature-controlled storage.
7. Viessmann Refrigeration Solutions
- Headquarters: Hof, Germany
- FY Revenue: Private
Viessmann has built a strong position in refrigeration for supermarkets, convenience stores and food retail environments.
The company combines refrigeration technologies with digital monitoring and energy management systems. These help retailers improve operational efficiency.
8. Cool Germany

Industry Outlook
Germany’s refrigeration market is being shaped by three major forces:
- Regulation. The European Union’s F-Gas phase-down and Germany’s environmental incentive programmes are accelerating investment in natural refrigerants.
- Technology. Modern transcritical CO₂ systems have overcome many of the efficiency concerns that once limited their adoption. Parallel compression and ejectors now let CO₂ systems perform efficiently even during high summer temperatures.
- Energy integration. Many modern German supermarkets no longer require separate heating systems. Waste heat from refrigeration equipment is recovered and used to heat stores and provide hot water.
The environmental differences are substantial:
- Traditional refrigerant R404A has a Global Warming Potential (GWP) of nearly 3,900.
- CO₂ (R744) has a GWP of 1.
- Propane (R290) has a GWP of 3.
