Mobile ultra-low temperature freezer Stirling Ultracold ULT25NEU

Unique in its class! A mobile ultracold freezer that runs on a vehicle battery or any power outlet.

Stirling's technology is the first of its kind to enable a portable ultracold freezer box to be manufactured that transports samples at temperatures of up to -86°C with a refrigerating capacity that can also be produced through a 12-volt vehicle connector.

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 -86°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.
