Refrigeration
Reliable refrigeration for commercial, industrial and special applications
Refrigeration removes heat from a medium and transfers it to the surrounding environment to create controlled temperatures. Refrigeration systems are essential for food preservation, industrial production, cold storage, transport, and process cooling. Depending on the application, high energy efficiency, reliable temperature control, and future-proof refrigerants are required. BITZER supplies key components such as refrigeration compressors and system solutions that help achieve efficient, reliable, and sustainable refrigeration across a wide range of applications.
How Does Refrigeration Work?
Closed circuit with compressor and refrigerant
Most refrigeration systems operate with a closed refrigerant circuit that continuously transfers heat. Four main components work together to generate reliable cooling:
- The compressor increases the pressure and temperature of the refrigerant.
- The condenser dissipates heat.
- The expansion valve reduces the pressure.
- The evaporator extracts heat from the environment.
This creates the desired cooling capacity.
Refrigeration Applications
Industrial refrigeration
A central component of modern production and logistics processes: in food processing, the pharmaceutical industry and logistics, precise cooling ensures quality, safety and efficiency.
Commercial refrigeration
Fresh food at all times – regardless of outside temperatures: this requires a stable, uninterrupted cold chain right through to the supermarket shelf.

Ultra-low temperature cooling
Precise and reliable cooling for applications requiring particularly low temperatures. Ultra-low temperature cooling is essential for demanding processes in industry, research and medicine.
Why Refrigeration Is Indispensable
Where Quality, Safety, and Availability Depend on Stable Temperatures
Refrigeration protects products, stabilizes industrial processes, and enables safe storage and transportation. It supports food safety, reliable cold chains, efficient production, and comfortable indoor environments while helping reduce waste and energy consumption.
