Cryomech, Inc. manufactures single and two stage cryorefrigerators (cryocoolers) based on both the Pulse Tube and the Gifford-McMahon Cycles. In the 4K temperature range, we offer Pulse Tube Cryocoolers achieving low temperatures down to <2.7K and with capacities as high as 1.5 watts @ 4.2K. For higher temperatures, we offer cryocoolers with capacities as high as 100 watts at 30K or 600 watts at 77K.
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.
