Cryomech manufactures over 30 different types of Gifford-McMahon and Pulse Tube Cryorefrigerators. While our competition is focused on providing large volumes of the same types of systems, we strive to customize our products to be easily integrated into your individual application. The more specialized and elaborate, the better.
Our fast and open design process allows you to remain the expert in your field of research and the design of your device. Once you decide the most important operating parameters for you, our customization experts are off and running. Cryomech is motivated to provide you with the best product while providing you the shortest lead time possible.
Whether you are condensing and liquefying cryogens or conductively cooling your sample, Cryomech has the appropriate Cryorefrigerator for you.
Liquid Helium Management Products
Cryomech is leading the helium conservation movement with the largest selection of laboratory scale helium recovery and liquefier options on the market, with hundreds of successful installations to prove it. Off-the-shelf solutions are available that can easily be configured to meet your needs. Further customization is available, and Cryomech’s dedicated research and development team welcomes your hardest recovery challenges as new opportunities. But which recovery solution is right for you?
Some of the systems offered by Cryomech:
- Pulse Tube Cryorefrigerators
- Helium Reliquefiers
- Liquid Helium Plants and Recovery Systems
Cryomech cryostats all feature a sleeve and helium reservoir design that provides refrigeration without any direct mechanical contact between the cooling station and the cryorefrigerator. This design feature provides the ultra-low vibration operation required by the most sensitive cryogenic devices.
Excellent Temperature Stability
Another benefit of the Cryomech reservoir design is the thermal inertia added by the accumulated liquid helium. This thermal inertia results in cooling stations with excellent temperature stability. All Cryomech cryostats exhibit inherent temperature stability of ± 5 mK.
Scientific research often requires specialized equipment that has never been built before. Cryomech recognizes this and encourages our customers to challenge us with their custom cryostat application. Customizable features include but are not limited to:
- Optical windows
- Location and number of instrumentation access points
- Clamping flanges for faster sample changes
- Sample stages with greater or less capacity
- Sample stage mounting hole patterns
Cold Helium Circulation Systems
Vibration-sensitive applications can be cryocooled in the 20-100K range by the Cryomech Cold Helium Circulation Systems. The customer’s object is cooled by mounting it to a cold finger through which circulating, constant-pressure, cold helium flows to absorb the heat load. The cold helium is cryocooled by a Gifford-McMahon Cycle Cryocooler separated from the cold finger by the flexible Cold Helium Transfer Line, eliminating the vibrations. The complete system is closed-cycle and operates with the reliability of the GM Cryocoolers and with a warranty of 10,000 hours. The CHCS comes in two capacity sizes: 120W and 200W @ 80K, the CHCS120 and CHCS200.
For customers experienced with open-cycle flow cryostats, the CHCS is essentially a cryocooled open-flow cryostat type system. Where the open end of the flowing cold cryogen has been closed off and repumped, recryocooled, and recirculated so no cryogens are needed. Inside the vacuum chamber assembly, the cold head of the AL Series Cryocooler interfaces with the circulating cold helium. It is here that the heat load added to the cold finger is pumped out of the CHCS. The compressor package, the cold head, two flexible lines and motor cord make up the components of the Gifford-McMahon Cycle Cryocooler.
