The compressed air output from the air compressor can reach 180 ° C. At this temperature, the moisture of the air is completely gaseous. The function of the aftercooler is to cool the high temperature air at the outlet of the air compressor to below 40 ° C, and condense a large amount of water vapor and metamorphic oil mist into liquid water droplets and oil droplets to remove them.
There are two types of aftercoolers: water cooled and air cooled. Because the temperature after water cooling is low, more water can be removed, so a water-cooled aftercooler is commonly used. The air-cooled aftercooler is used in places where the water quality is hard or the water is difficult to obtain.
An aftercooler will help you reduce equipment maintenance time and wear.
