Cryomech is know for being at the forefront of Pulse Tube (PT) cryocooler development. Their cryocoolers are highly reliable and offer a mean time between maintenance unmatched by any GM-type cryocooler.

The Cryomech PT Cryocoolers require minimal general maintenance and are ideal for vibration-sensitive applications. They directly liquify helium gas and recondense biol-off in liquid cryostats. They also provide direct conductive cooling in dry cryostats (including low-vibration options).

The operation of a cryogenic refrigeration system is based on a closed-loop helium expansion cycle. A complete system consists of two major components: One is the compressor package, which compresses refrigerant and removes heat from the system; the other is the cold head, which takes refrigerant through one or more additional expansion cycles to cool it down to cryogenic temperatures. The refrigerant gas used in the Cryomech cryogenic systems is 99.999% pure helium. Flexible stainless-steel lines called ‘helium flex lines’ carry compressed helium from the compressor package to the cold head and carry low-pressure helium back.

The compressor package works as follows: An oil-lubricated compressor compresses the pure low-pressure helium that is returned from the cold head. The heat of compression is removed via a heat exchanger, and the oil from the compression process is removed in a series of oil separators and filters. The compressed helium is then fed to the cold head via the high-pressure helium flex line.

In the cold head, adiabatic expansion of the helium and further heat removal allows cooling to cryogenic temperatures. The low-pressure helium then returns to the compressor package via the low-pressure helium flex line.

All of our equipment is used and reconditioned. Our technicians test all equipment to confirm that it operates properly and to the manufacturer’s specifications. While we can’t test for a specific analytical application, we will do our best to simulate the conditions under which the equipment will be run. If you have particular testing requirements or requests please let us know and we’ll work with you to make sure these requirements are addressed during testing.

The photos above are representative. Please bear in mind that the equipment shown is currently in storage in our warehouse and that in addition to testing each machine we will clean all the equipment thoroughly prior to shipment. We often have multiple units of each model in stock and sometimes we're unable to feature photos of every single unit. At your request, we can provide photos of the equipment in your order after it has been tested and cleaned.
