CryoTel® CT

CryoTel® Cube

The DS 2.1 cryocooler brings gas bearing technology to the mini-cryocooler market. The DS (Dual Split) features dual-opposed pressure wave generator pistons and a split cold head to minimize exported vibration and acoustic noise. The optional passive balancer will further reduce cold head vibration for sensitive applications.

CryoTel® DS 1.5

​The GT Cooler was brought to commercialization in 2005. The GT 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® GT is the smallest 16W @77K cooler available at an attractive price point with a Mean Time to Failure of over 200,000 hours.

Sunpower introduces the CryoTel® Cube cryogenic cooling system incorporating the CryoTel GT cryocooler. Users can turn on the Cube and have instant cryogenic cooling from a maintenance-free solution that eliminates the hassle of handling liquid nitrogen. The CryoTel Cube can operate in multiple orientations with no degradation in performance. The cryocooler is mounted on vibration isolation mounts to reduce exported vibration. An optional Active Vibration Cancellation system further reduces exported vibration to levels consistent with liquid nitrogen.

CryoTel® DS 2.1

Space Cryocooler

As of May 2015, there have been a total of 52 successful CT-F cryocooler launches into space.  The Sunpower cryocooler in the RHESSI satellite was launched February 5th, 2002 and has been in continuous operation since.   We believe this speaks volumes about the robustness of the CryoTel line of cryocoolers.

​The CryoTel® Generation II controller was introduced in April of 2012 to respond to the market need for additional functionality and reduced audible noise.
The Generation II controller offers the following attributes:

Additional functionality
Included enclosure
Reduced audible noise
Tunable temperature control loop
Sinusoidal driving frequency
A reduction in lower order harmonic vibration induced by the controller
Isolated RS232
External and software commanded cooler shutdown

​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.
