The after cooler is a device that cools the high-temperature air at the outlet of the air compressor to below 40 ° C and condenses a large amount of water vapor and deteriorated oil mist into liquid water droplets and oil droplets in order to remove them.
The temperature of 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 after cooler is to cool the high-temperature air at the exit of the air compressor to below 40 ° C, and condense a large amount of water vapor and deteriorated oil mist into liquid water droplets and oil droplets in order to remove them.
Characteristics and uses
There are two types of aftercoolers: water-cooled and air-cooled. Because water-cooled temperatures are low and more water can be removed, water-cooled aftercoolers are commonly used. Air-cooled after cooler is used in places where the water quality is hard or it is difficult to get water. An aftercooler will help you reduce equipment maintenance time and wear. A properly sized aftercooler can remove most of the remaining water. Install piping to ensure that any remaining condensate is captured. In places with high gas demand, a 5-micron precision filter / pressure regulator / oil mister can be installed to remove the remaining water. Without an aftercooler, water vapor will suddenly be released into liquid water at the point of use. The water in the pipeline will affect the action, wash away oil mist on the surface of moving parts, corrode parts, and even freeze moving parts. The aftercooler will save your running costs. The higher the temperature of the compressed air, the less water vapor can be removed, which can lead to headache repairs and expenses.
