DN / ISO 25 STIRLING 1.5W SINGLE STAGE
WATER VAPOR CRYOPUMP
The Cryo-Water Pump25 is the midrange pumping speed member of the NanoStar* line of
cryopumps, based on the K548 1.5Wmidrange cryopump. It is specifically designed for tabletop
or small vacuum deposition tools and portable analysis systems.
Its small size can support GC/MS cryofocusing in portable Gas Chromatograph and Mass
Spectrometer systems. Pumping speeds support up to a 5 liter vacuum chamber.
The Cryo-Water Pump25 facilitates the elimination or the control of water vapor in small research
vacuum chambers. Combined with UV desorption / getter technology, NanoStar cryopumps
provide an effective means of water vapor reduction and control at UHV levels.
The Cryo-Water Pump25 mounts directly to a turbo pump or in situ in its own port. It can reduce
pump down time by >50% during atmosphere to HV / UHV vent - pump cycles.
Compact and completely self-contained, with the Cryo-Water Pump25 there is no need for big,
power hungry compressors or gas lines. The onboard microcontroller contains a temperature
controller which offers stand-by remote shutdown and overcurrent protection.
