Germany’s supermarket refrigeration sector has become one of the world’s most important testing grounds for low-emission cooling technologies. Tight European environmental regulations, generous government incentives and the dominance of highly efficient discount retailers have accelerated investment in natural refrigerants and energy-saving systems.
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 that 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, led by ALDI and Lidl, relies on highly standardised store formats and exceptionally tight operating margins. If a refrigeration technology proves successful across thousands of German discount stores, it often 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 when Epta completed its acquisition of Austrian refrigeration manufacturer HAUSER.
The deal created one of Europe’s largest commercial refrigeration groups, combining 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 after Haier Smart Home completed its $775 million acquisition of the business in late 2024.
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 while benefiting 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.
Its self-contained units are widely used by discount retailers because they require less complex installation and provide 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 and a specialist in transcritical CO₂ systems.
The company has developed advanced technologies such as parallel compression and ejector systems that 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 and 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, helping retailers improve operational efficiency.
8. Cool Germany
Headquarters: Germany
FY Revenue: Private
Cool Germany provides refrigeration engineering, maintenance and installation services.
The business plays an important role in helping retailers modernise refrigeration estates and maintain increasingly complex natural refrigerant systems.
9. Johnson Controls Germany
Headquarters: Germany operations
FY Revenue: Private
Johnson Controls remains a significant supplier of controls and building management systems used throughout the commercial refrigeration industry.
Its digital technologies help supermarkets monitor energy consumption, improve system reliability and reduce maintenance costs.
10. BITZER
Founded: 1934
Headquarters: Sindelfingen, Germany
FY Revenue: Private
BITZER is one of the world’s most important compressor manufacturers and has played a central role in the development of modern refrigeration systems.
Its compressors are used throughout supermarket refrigeration systems across Germany and around the world. The company has also invested heavily in technologies supporting natural refrigerants.
Industry Outlook
Germany’s refrigeration market is being shaped by three major forces.
The first is regulation. The European Union’s F-Gas phase-down and Germany’s environmental incentive programmes are accelerating investment in natural refrigerants.
The second is technology. Modern transcritical CO₂ systems have overcome many of the efficiency concerns that once limited their adoption. Technologies such as parallel compression and ejectors now allow CO₂ systems to perform efficiently even during periods of high summer temperatures.
The third is energy integration. Many modern German supermarkets no longer require separate heating systems. Waste heat generated by 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.
What Happens Next?
Germany is expected to remain one of the world’s leading markets for supermarket refrigeration innovation.
Large retailers are likely to continue replacing legacy HFC systems with natural refrigerant technologies while investing more heavily in digital monitoring and heat recovery.
The transition is creating opportunities across the Germany retail technology sector. For the Germany grocery store industry, refrigeration has become a strategic investment that directly influences operating costs and sustainability performance. Across the wider Germany FMCG sector, modern cold-chain infrastructure is helping improve food quality, reduce waste and strengthen supply-chain resilience.
