Pulse Tube Cryocoolers

Cryocoolers

Easy Maintenance

Cryomech Pulse Tube Cryocoolers offer a long mean time between maintenance and require minimal general maintenance.

Ideal for Vibration-Sensitive Applications

By design, Cryomech Pulse Tube Cryocoolers are ideal for vibration-sensitive applications due to their lack of moving parts. There are also different vibration management options and accessories available for the most vibration-sensitive applications.

Applications in Liquid Cryostats

Directly liquefy helium gas and recondense boil-off in liquid cryostats.

Applications in Dry Cryostats

PT Cryocoolers can be used to provide direct conductive cooling in dry (cryogen-free) cryostats. Low-vibration options are also available for these applications.

Cryocoolers

A Temperature Oscillation Damping Pot can be added to any Cryomech Two-stage Pulse Tube Cryocooler to increase temperature stability to +/-5mK. The compact and efficient design offers greatly decreased temperature fluctuations around 4.2K with minimal loss to your cooling capacity and base temperature.

This option gives customers the ability to create liquid helium for external helium circuits. Only available with our two-stage PT Cold Heads, this built-in liquefying circuit liquefies helium and directs the liquid through a VCR fitting. The helium gas enters the circuit through a fitting on the base plate. The helium is then pre-cooled at the first stage heat exchanger, then cooled again on the exterior of the second stage regenerator tube. Lastly, the circuit directs the cooled helium to the second stage heat exchanger, where it condenses.
