Working Principle

1.The basic principle of Ultra-Low Temp. Water-Cooled Chiller is that under ultra-low temperature, the movement of molecules is slowed down until the surface of the trapped and frozen cryogenic coiled tubes is slowed down, and the vapor is easy to be arrested, set and frozen, and the capture rate is high.

2.The secondary supercooling technology is adopted, with rapid refrigeration and low temperature.

Widely used in petrochemical industry, pharmaceutical and medical treatment, biochemical engineering, biological freeze-drying, aerospace industry, semiconductor manufacturing, university research institutes and other high-tech industries.

Supporting equipment: provide cold source for production process of various reactors, vacuum chambers, experimental instruments, microchannels, etc., and also cool semiconductor equipment, mechanical equipment, dryers, evaporators, etc;
