Freezing type compressed air dryer is widely used, economical compressed air drying equipment. RD series freezing type dryer is the use of advanced technology and imported parts manufacturing, can be matched with any air compressor to remove the compressed air in the water, gas quality reaches the pressure dew point of 2-10 degrees.

When the temperature is decreased, water capacity of air was also decreased, the water will become gaseous liquid, freezing type dryer is the use of this principle. Firstly the dehumidification of compressed air cooling, the gaseous water condensed into liquid, then through the gas-liquid separating separator, after the water will drain valve thus, dry compressed air
