1.Working principle According to the principle of freezing and dehumidification,The hot and humid compressed air is exchanged for heat through an evapora-tor,so that the gaseous moisture of the compressed air condenses into liquid water.form liquid water through gas-water separation,and dis-charge it through the gas-water separator. 2.Technical Index Capacity:1~300Nm3/min Operationg pressure:0.2~1.0MPa(can provide 1.0~3.0MPa) Dew Point:≤-23℃ Cooling Method:Water-cooling Inlet air Temperature:≤45℃ Inlet Water Temperature:≤32℃ Inlet Water Pressure:0.2~0.4MPa
