Product feature 

1. Prevent ice blockage

The main function of the cold dryer bypass valve is to prevent ice blockage. When the air handling capacity of the 

cold dryer decreases, the excess cold capacity in the evaporator will be too large, causing the temperature of the 

evaporator cavity to drop below 0 degrees Celsius, and the condensed water will freeze, causing "ice blockage", 

which will lead to gas blockage and make the cold dryer unable to work normally. The bypass valve effectively 

prevents the occurrence of ice blockage by introducing high-temperature and high-pressure gas.


2. Improve equipment operation efficiency

The bypass valve adjusts the refrigerant evaporation temperature to ensure that the cold dryer operates at a suitable 

temperature, thereby improving the operating efficiency of the equipment.


3. Extend equipment service life

The precise control and adjustment function of the bypass valve can reduce the risk of compressor damage due to

 "liquid hammer", thereby extending the service life of the equipment.
