Cryotel® Cryocoolers

Sunpower’s CryoTel cryocoolers are the result of over 30 years of technical leadership, innovation and evolution in free-piston Stirling technology.  Our cryocoolers are cost effective, low in vibration, and extremely efficient.  In fact, you will not find a more efficient cryocooler on the market.  Since they require no maintenance, our customers can expect many years of high-performance, trouble-free cooling.

With Sunpower’s reputation for exceptional performance and reliability, the CryoTel family of cryocoolers is increasingly used in the medical, instrumentation, aerospace, research and development, security, astronomy, telecommunications, and pharmaceutical markets.  In addition, Sunpower’s cryocoolers integrate with and support technologies such as high temperature superconductivity,  mass spectrometry, optics, NMR, detectors, gas liquefaction, low noise amplifiers, and more.

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

The most efficient cryocoolers on the market

The graph below is a comparison of the efficiencies of the all of the known commercially available cryocoolers with 1 – 20 watts lift, expressed as a percentage of Carnot efficiency, verse the heat lift the cryocooler provides at 77 Kelvin expressed in watts.  From this data it is clear the CryoTel line of cryocoolers are the most efficient cryocoolers on the market.
