Pulse Tube Cryorefrigerators (PTR) are available in single and two stage models. All Pulse Tube Refrigerators reach cryogenic temperatures without the displacers that cause vibrations. This reduction of the cold moving parts increases the mean time between maintenance, while decreasing noise and vibration. The PT405, a two stage Pulse Tube Refrigerators obtains a low temperature of < 2.7K, in both 50 and 60 Hertz power regions. We also offer the PT805 which cools to <8K. Our new PT60 is a single stage Pulse Tube Refrigerators  which cools to <30K, has 60 watts of capacity at 77K, for an input power of 3 kW.

Cryomech's Gifford-McMahon Cycle Cryorefrigerators are available in single or two stage models. The single stage G-M's, the AL Series, reach a low temperature of either 10K or 25K in 20 minutes and are maximized for price and capacity from 10-80K. The two stage Gifford McMahon's, the GB Series, cool down to 6.5K on the second stage with the first stage supplying cooling from 40-80K. When cooling devices to below 20K with the second stage a GB Series Cryorefrigerator, the first stage supplies the power to intercept heat at a higher temperature, therefore shielding the second stage from unnecessary heat.

Cryomech, Inc. manufactures water and air cooled compressors for each cryorefrigerator. The Pulse Tube Refrigerators  and Gifford McMahon Cycle Cryorefrigerators both include a cold head, compressor package (with power cord to supply electricity to the cold head motor) and two flexible gas lines.

All Cryomech Pulse Tube Cryorefrigerators are covered with a 3 year or 12,000 hour, whichever comes first, warranty. The warranty on the GMs is 3 years or 8,000 hours, whichever comes first.
