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.



Our Solutions are Trusted Across Many Applications

James Mead, Critical Systems Supervisor, Fred Hutch Cancer Research Center in Seattle, WA:

“We did some operational and energy-use studies over a six-month period and were shocked because the energy consumption was so much lower compared to what we were using. Our studies found all claims by the company to be true, if not conservative.”

Brian Cayen, Research Information Services & Operations Manager, Ottawa Hospital in Ontario, Canada

“The first freezer that was replaced in one of the labs reduced heat generation and allowed us to turn off one of the two air conditioning units, and the temperature in the room still dropped by 2°C.”

Dr. Jeffrey Warren, Executive Director of the North Carolina Policy Collaboratory in Chapel Hill, NC:

“Even for the large units that can hold 58,000 vials, that was the best money I’ve ever spent. I could give 9 or 10 reasons why to buy Stirling products.”

Major General Jose J. Reyes of the Puerto Rico National Guard in San Juan, PR:

“Stirling Ultracold is and has continued to be that solution – playing an integral role in helping us tackle and eliminate Puerto Rico’s unique challenges and enabling COVID-19 biologics accessibility to the entire island and our cherished communities within it.”
