working principle

Freezing dryer is the use of frozen dehumidification principle, compressed air drying equipment, the use of imported high-quality components, reliable performance, stable operation, low noise, low energy consumption, no basic installation, it is more widely used.

Gas system

The compressed air is cooled down to 2 ° C ~ 10 ° C by the efficient pre-cooler ③ and the evaporator ④, and then enters the air-water separator ⑥ to remove the condensed water, finally returns to the high-efficiency precooler for reheating, recovering part of the heat and obtaining stable dew point compression Air, and can effectively prevent pipe condensation.

Refrigerant system

After the refrigerant is supercharged in the refrigeration compressor, the refrigerant is condensed or cooled, and then converted to a cryogenic liquid into the evaporator ④ to absorb the heat in the compressed air and then vaporize, and then circulated through the gas-liquid separator to circulate and compress the refrigeration compressor.
