CryoTel® CT

CryoTel® cryocoolers, Sunpower’s Stirling cryocoolers, are the result of over thirty years of technical leadership, innovation and evolution in free-piston Stirling technology.

With Sunpower’s reputation for quality and performance, the CryoTel® family of cryocoolers is increasingly used in the medical, instrumentation, security, astronomy, telecommunications, and pharmaceuticals markets.

Sunpower’s cryocoolers integrate with and support technologies such as high-temperature superconductivity, radiation detection, optics, CCD, LNA, gas liquefaction, and more.

The CryoTel® cryocoolers provide cost advantages during product development and during volume production.

Our customers also benefit from the unsurpassed reliability, efficiency, and power density of our superior cryocooler technology.

Our cryocoolers are exceptionally quiet, low in vibration, environmentally friendly, and extremely efficient.

There are no maintenance requirements so our customers can expect many years of high-performance, trouble-free cooling.

The CT Cooler was brought to commercialization in 2001 after 10 years of cryocooler development at Sunpower.

The CT stands for CryoTel®, as the first commercial application was for the telecommunications industry.

The CT has been used successfully in applications such as High Temperature Superconductivity (HTS) filters, high altitude balloons, refrigeration, germanium detectors, IR detectors, radio telescopes, laser diode cooling, and research among others.

We believe the customer will agree that the CryoTel® CT is the smallest 11W @77K cooler available at an attractive price point with a Mean Time to Failure of over 200,000 hours.
