The compressed air dryer in the refrigerator allows the moisture in the compressed air to condense into droplets by cooling, to achieve the purpose of reducing moisture content. The viscous drops are drained from the automatic drainage system.
In a refrigerated air dryer, the compressed air is cooled to about 35 degrees Fahrenheit. After the air passes through the intake valve, the water vapor is extracted and drained, and the freshly drained air is reheated by the intake air. You can also purchase refrigerated air dryers through various online sites.

At the end of each cycle, the compressed exhaust air has a dew point in the range of 35 to 40 degrees Fahrenheit. In general, the air-drying process creates a more hygienic working environment, which is also much cheaper to manufacture.
In the case of a non-cycle refrigerant dryer, the refrigerant circulates continuously in the engine. This allows the rapid reaction to changes in load, either with low or high humidity densities in the intake air.
The combined dryer is equipped with a refrigeration dryer and a dryer, which is equipped together, the air treated with the refrigeration dryer comes directly from the dryer air-water separator to the absorption dryer, does not pass through the pre-cooler.
The air temperature flow includes about 2 -5, the dew point about 5, at this point the air will enter the absorption dryer and be absorbed deeper, the dew point will be better when the air temperature is lower.
This means that combi dryers can reach a much more stable dew point.
