Stirling Ultracold
Ultra-Low Temperature Freezers
We were the first to bring revolutionary technology to -80°C ultra-low storage, that not only makes significant energy savings possible, but also enables true environmental sustainability. Our freezers were the first to use all-natural refrigerants and our SU780XLE was the first ULT freezer to be ENERGY STAR® certified. We changed the industry by making real laboratory sustainability possible through our innovative free-piston Stirling engine.
