Refrigeration dryer

The compressed air first enters the pre-cooler for preliminary cooling, and then flows into the regenerator to exchange heat with the returned product gas to further cool the compressed air and discharge the condensed water out of the machine. After that, the compressed air flows into the evaporator and exchanges heat with the refrigerant to further cool the compressed air to reach the required dew point temperature.

  • High-efficiency three-in-one plate-fin heat exchanger: the inlet temperature difference is as low as 5℃
  • High-efficiency water separator: water removal efficiency of 99%
  • The relative humidity of the compressed air at the outlet is as low as 20%, and there is no risk of pipeline corrosion
  • Energy consumption is reduced by 50% compared with the cold dryer using shell and tube heat exchangers
  • Efficient R410A environmentally friendly refrigerant

The amount of water vapor in the compressed air is determined by the water content of the compressed air. Under the condition that the compressed air pressure is kept basically unchanged, when the temperature drops, the water-holding capacity of the air also decreases, and the water that was originally a gas will become a liquid. Based on this dehumidification principle, the refrigerated dryer uses a refrigeration device to cool the compressed air to a certain dew point temperature, so that the gaseous water in it is condensed into a liquid state. Then, the gas and liquid are separated by the separator and the water is discharged by the automatic drain, so that the compressed air is dried.

The cooling and cooling device of the air-cooled refrigerated dryer is an air-cooled radiator. The heat of the high-pressure part of the refrigeration system is blown to cool by the fan, and taken away with the air volume blown by the fan.
