The K570 is the smallest and the lightest of the range of 1w@80k cryocoolers and delivers required heat loft over the extended range of ambient temperatures from -50° up to +85°, along with MTTF well in excess of 30,000 hours. The K570 cryocooler is an ultimate solution for demanding military tactical (MWS, gen 3, ulitspectral IR sensors and responsive space programs. Where weight, size, power consumption, heat sinking, reliability, flexibility in system design, vibration export and aural stealth are of concern
