Micro-miniature cryogenic refrigerators

CryoTech is a startup company founded in 2018 — the first startup member of the Gevasol Group.

Micro-miniature cryogenic Stirling refrigerators are primarily used for military infrared applications. CryoTech’s major price reduction enables the application of this technology to civilian purposes such as advanced driver assistance, enhanced vision systems for aircraft landing, gas leak detection, remote fever detection, etc.

CryoTech’s cryogenic refrigerators are compact and lightweight yet very powerful and cost-effective.
