Flake ice-maker and ice-maker；
Water Chiller,
low-temperature cooling circulator ；
low-temperature magnetic stirrer；
Vacuum freeze dryer；
high-speed cooling centrifuge；
Constant-temperature water bath and oil-bath；
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.


Our experienced engineers can offer first-rank service and technical support for end-users and distributors.
