Micro-miniature cryogenic refrigerators

CryoTech is a young 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 major price reduction enables application of this technology for civilian purposes such as advanced driver assistance, enhaced vision systems for aircraft landing, gas leak detection, remote fever detection, etc.

CryoTech’ cryogenic refrigerators are compact and light weight yet very powerful and cost effective.
