The air compressor is equipped with a dryer. Why is there still a lot of water?

After the screw air compressor unit is equipped with a dryer, there is still a lot of water in the unit system. I believe that many users who use air compressors have encountered this problem. The following is an analysis of the reason for everyone.

In the post-processing equipment of screw air compressors, there are mainly air tanks, dryers and filters. The dry compressed air can ensure the unimpeded operation of the air system and production process of the air compressor.

The function of the dryer is to eliminate the condensed water in the compressed air and ensure the discharge of dry and clean compressed air. After equipped with the relevant dryer, but the compressed air still contains water, this is because of these reasons.

1. The air humidity around the air compressor station is too high
The air itself has humidity and contains a certain amount of moisture. When the air is compressed, due to the high temperature inside the compressor, the moisture directly evaporates to form water vapor, which is then discharged from the compressor according to the pressure. When the compressor is shut down, the temperature drops, which will cause water vapor. Condensate is formed. Therefore, the humidity of the working environment of the air compressor should be low, or the condensed water should be discharged before starting the use.

2. Failure of post-processing drying equipment
The post-drying capacity of a general refrigeration dryer is 3°C. If the temperature of your work site is lower than 3°C, there will be water. At this time, it is recommended to configure a post-treatment drying equipment with a micro-heat suction dryer, and the pressure dew point can reach -20°C without producing water in it.

3. The post-processing drying equipment equipped with the air compressor has insufficient capacity
Generally speaking, the post-drying treatment capacity configured by the manufacturer for the user is configured according to the average air consumption. If your instantaneous air consumption is large, the capacity of the post-treatment drying equipment will be insufficient, resulting in water in the air.

4. The gas storage tank itself has the function of water accumulation
There was a lot of water in it that was not drained out, so forget to drain it. Open the drain valve under the gas tank regularly to drain the water.
