Extra-Low-Temperature Cooling

Extra-low-temperature cooling is required whenever standard refrigeration systems can no longer achieve the necessary temperature range. Temperatures below –50°C are commonly used in climate test chambers, environmental simulation, blast freezing, pharmaceutical processes, materials testing, and scientific research. These applications demand reliable temperature control, high energy efficiency, and maximum process safety. 

BITZER provides compressor solutions for ultra-low-temperature refrigeration systems, including demanding applications with very low evaporation temperatures and cascade refrigeration systems. Select your application and discover suitable BITZER products for your temperature range and capacity requirements.

Extra-low-temperature cooling describes refrigeration processes that generate temperatures below approximately –50°C. These ultra-low-temperature conditions are required when products, materials, or components must be tested, stored, or processed in extremely cold environments. Typical applications include: 

• Climate test chambers
• Environmental simulation systems
• Industrial process cooling
• Blast freezing 
• Scientific research

Because operating conditions become increasingly demanding at very low evaporation temperatures, refrigeration systems often use specially designed compressors and cascade refrigeration technology to ensure reliable operation, temperature stability, and energy-efficient performance.
