In the process of using the refrigerated air dryer, the situation of "normal operation of the equipment but great pressure drop" often occurs. So why is this problem?

First of all, we understand the "working principle" of the refrigerated air dryer.

working principle

The amount of water vapor in compressed air is determined by the temperature of compressed air: the pressure of compressed air is basically unchanged. Reducing the temperature of compressed air can reduce the content of water vapor in compressed air, and the excess water vapor will condense into liquid. Cold dryer is to use this principle, using refrigeration technology to dry compressed air.

Problem analysis and Solutions
01 Problem analysis
1. Low inlet pressure
2. he pipeline valve is not fully opened
3. Too small pipe diameter, too many elbows or too long pipeline
4. Ice blockage of evaporator
5. Filter clogging
6. Excessive water accumulation in equipment
7. The processing capacity of the selected model is too small

02 solution
1. increase the air inlet pressure
2. Open all air line valves
3. Improve air piping system
4. Increase the compressed air flow or load; adjust the hot gas bypass valve and expansion valve or replace it to maintain the evaporation temperature above 0 ℃
5. Replace the filter element
6. Check drainage system, repair or replace
7. Increase the equipment or replace the equipment model with larger processing capacity
