CRYOGEN FREE
CRYOCOOL-CF3
Cryogenic Gas Stream Cooler for X-ray Crystallography
with
Never-ice Technology
The Refrigerator
The GM refrigerator cools the nitrogen gas stream.
Technology Transfer
Developed for NASA to test gas sensors, this proven technology has now been transferred for use in crystallography.
Continuous cryogen free operation, unmatched performance and push-and-play operation are just some of the features.
Warm gas is cooled by the two refrigerator heat stations.The refrigerator operates on the Gifford-McMahon (GM) gas expansion cycle. A compressor circulates helium gas to and from the refrigerator. This compressed gas is cooled by expansion, providing heat removal at the two refrigeration stations. Similar to a standard room air conditioner, the refrigerant gas is used over and over (closed cycle). Heat exchangers attached to the refrigerator stations cooldown the gas ‘stream’ used to cool the samples.
PUSH-AND-PLAY
OPERATION
1. Start the gas flowing
(nitrogen or helium)
2. Turn-on the never-ice system
3. Push the compressor
‘ON’ button
4. Watch the system automatically cool and hold the preset gas stream temperature.
