Cryogenics
Cryogenic turbines and compressors serves in the area of research works, health or industry like operational parts of the liquefiers or industrial gases as are helium, nitrogen or oxygen.
Small helium expansion turbines are designed directly to gas liquefying – for example on the colleges and cryogenic laboratories. Cold compressors and pumps are instrumental to exhaustion and precooling of gases – for example helium vapors after sensor supercooling in the CERN accelerators and colliders.
Cryogenic compressor
The centrifugal compressor is designed for helium vapor exhaustion. It is driven by a variable frequency electric motor. High quality precision hybrid ball bearings with ceramic balls provide long-life operation. Motor and bearing system operate at ambient temperature. An integrated doublesealing system with vacuum interspace provides full protection against process contamination by air and separates motor and compressor section, which operates at -270 °C. Both products are used for example in CERN in Switzerland, where fulfilling all requirements for parameters.
HCCU 1, HCCU 2Helium expansion turbine
The helium expansion turbine is a small expansion turbine whose rotor is supported on the dynamic gas lubricated bearings. The rotor uses eddy-current brake cooled by water. Operation is helium leakage free. Small expansion turbines are mainly used in the process of gas liquefying in small helium liquefiers.
