Stirling Ultracold VAULT100 ULT freezer – the revolution
World first! Temperature range from -20°C to -100°C. Best temperature uniformity. Up to 70% energy savings. 795 liters of storage volume on less than one square meter of floor space. 6-year warranty!

The innovative Stirling Ultracold ultra-low temperature freezers utilize a free-piston Stirling engine to achieve highly efficient storage of general laboratory materials ranging from -20°C to -100°C. Conventional ultracold freezers employ a compressor system that is highly susceptible to wear and tear and has a short useful life. The Stirling ultra-low temperature freezers do not use compressor-based or cascade refrigeration systems; they use patented free-piston Stirling engine technology that was originally developed for energy, aerospace and industrial applications before its successful commercial application in ultra-low-temperature cooling systems.
