This paper focuses on the design and development of the CryoTel™ family of cryocoolers, which currently consists of the CryoTel™ CT and the CryoTel™ MT. The CryoTel™ is based on Sunpower’s M77 and M87 cryocoolers with design enhancements to allow for operation in applications with ambient operating temperatures that range from −40 °C to +60 °C. The CryoTel™ is a linear free piston integral Stirling cryocooler that makes use of gas bearing technology for non‐contact operation and a Digital Signal Processor (DSP) based controller with closed‐loop temperature control. The CryoTel™ and controller can be configured to operate across a wide range of input voltages including 24 Vdc to 240 Vac.The CryoTel™ CT weighs 2.7 kg and has a cooling capacity of up to 11 W @ 77 K with 160 W of input power. The CryoTel™ MT has a cooling capacity greater than 5.0 W at 77 K with 80 W of input power and weighs 1.65 kg.These cryocoolers can be modulated and operate efficiently over a wide range of heat loads and ambient conditi...
