VRD Series
Refrigerated Air Dryer
For Compressed Air
Working Principle Of Refrigerated Dyer
The amount of water vapor in compressed air is determined by the temperature of the compressed air:Lowering the temperature while maintaining the same pressure can reduce the content of water vapor decreases, and excess water vapor condenses into a liquid. Freeze drying air dryer uses a refrigeration type device to cool compressed air to a certain dew point temperature, precipitation of water, discharge of water, thus drying compressed air.

Working pressure and temperature correction coefficient (V1)
Environmental temperature correction coefficient (V2)
When selecting a dryer, it is necessary to consider the pressure correction coefficient and temperature correction coefficient. The standard operating conditions for refrigerated dryers :
1. Inlet pressure: 0.70Mpa
2. Inlet temperature:50℃
3. Environmental temperature: 32℃
When selecting the model, it is necessary to consider the coefficients corresponding to the actual working conditions for correction. If you need detailed technical support, please contact our company directly
