Cryogenic coolers or cryocoolers

Joule Thomson cryogenic coolers also called JT cryocoolers are small cooling devices used for cooling down sensors which require high speed and stable cryogenic temperatures and are powered by different compressed gases. Stirling type coolers are usually used to cool down sensor array devices which are connected to stable electricity source. Both type cryocoolers are used to cool down to cryogenic temperatures. Le-tehnika produces miniature cryocoolers used in mobile applications in field or applications which require small form coolers to fit into special housings. Their energy consumption is extremely low. Following are main applications: IR cameras, IR detectors in gas leakage control devices, high precision night/fog/rain cameras, heat source detectors.
