Refrigerated Dryer is the most widely used and economic drying equipment. LC Series refrigerated dryer we manufactured is to use the advanced technology and some imported parts with the match of any air compressor to remove the moisture in the air,its dew point can reach 2-10 . When the temperature drops, the waterr capacity in the air also decreases, the former gaseous water will become liquid. That is, refrigerated dryer uses the dehumidifier principle. First of all, cooling compressed air, make the gaseous water condenses as the liquid state. Then through the separator makes gas-liquid separation. Finally the moisture is discharged by the drainage valve and the dry compressed air is obtained
