Air Compressor Line Cooler

Aftercoolers reduce the amount of water vapor in a compressed air system by condensing the water vapor into liquid form.

Air compressor line cooler.

Aftercooler system consisting of a b m model 70266 11 x 8 x 1 tranmission engine oil cooler an ebm pabst model w2e250 hl06 01 230v ac fan 1160 cfm in open air wired in parallell with the motor so when the motor runs the fan runs and a wilkerson model x01 04 m00 automatic drain. Aftercoolers are heat exchangers for cooling the discharge from a air compressor. The compressed air enters the air cooled aftercooler. Removing the liquid requires a moisture separator and a drain valve.

Air cooled aftercoolers use ambient air to cool the hot compressed air. If the temperature at the discharge port exceeds 300 degrees fahrenheit the refrigerant oil and adjacent mechanisms. This fellow measured his compressor outlet. They use either air or water and are an effective means of removing moisture from compressed air.

In a reciprocating air compressor for example the air temperature will drop anywhere from 50 degrees fahrenheit to 75 degrees fahrenheit across the roughly six inches of travel between the discharge port and discharge line. Low cost air dryer water separator. Post cooling all that water is still in the air line. In small air systems 20 hp it s common to see the receiver tank used to separate and collect liquids.

Cooling condenses lots of water.
