Stirling Ultracold

Stirling Ultracold manufactures and sells environmentally sustainable ultra-low temperature (ULT) freezers for the global market. Powered by the free-piston Stirling engine, and the first in the U.S. to use 100% natural refrigerants, these upright and undercounter ULT freezers use less than one-third the electricity of standard compressor-based ULT freezers, as validated by the industry's first ENERGY STAR® partnership for ULT freezers. The company also produces the industry's only portable ULT solution available for remote clinical trials and biologic drug delivery.
