For the best films and fastest pumping times, it is critical to remove water vapor from the process environment. The VaporCold closed-cycle Cryochillers provide efficient water vapor pumping with lower total operating costs than liquid nitrogen. VaporCold  offers cryochillers in a number of sizes and capacities, with single and dual channel models available.
VaporCold offers cryochiller Coil and Meissner trap design and configuration services. Contact VaporCold Sales for design support.
VaporCold cryochillers provide efficient closed-loop cryogenic refrigeration for water vapor pumping with cooling capacities from 500W to 4200W. VaporCold cryochillers support full system integration and RS485 communications.Optional Ethernet  interfaces are available. The PLC+HMI control system  will meet your remote operation needs and supports complete data-logging.  Analog system control is also available. The touch panel allow rapid scrolling through all available monitor points. Likewise, all available monitor points can be sent remotely to a deposition controller for automated operation.

Ultra-low refrigerator;

The water chiller has provided for laboratory equipment, for instance XRD, XRF, AAS, ICP, ESCA, TEM, MRI, MBE, MOCVD, Electron probe, Laser, Vacuum Brazing Furnace, Oxygen/Nitrogen Analyzer, Thermal simulation tester, etc.

The YKKY series water chiller adopts the integrated structure; the unit includes: water circulation system, refrigeration system, and electric control system. The unit has used the high efficiency condenser, a slow-speed fan, in did not reduce the refrigeration quantity in the situation to reduce the system noise effectively. The electrical control has provided perfect system protection and the fault indicator function, further reduced unit’s failure rate, simultaneously has provided conveniently for the diagnosis.

The YKKY series water chiller has perfect protection. The breaker makes the short circuit protection. The compressor, the water pump, the fan have the overflow protection; the compressor has the overpressure protection. The water chiller will stop automatically when low-level water in tank, water temperature is too high or too low. The compressor will stop automatically when refrigeration system pressure is too high.
