Make no mistake a cooler alone does not yield high quality compressed air.
Air compressor line cooler.
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.
Aftercoolers reduce the amount of water vapor in a compressed air system by condensing the water vapor into liquid form.
Air cooled aftercoolers use ambient air to cool the hot compressed air.
The compressed air enters the air cooled aftercooler.
Low cost air dryer water separator.
In small air systems 20 hp it s common to see the receiver tank used to separate and collect liquids.
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.
They use either air or water and are an effective means of removing moisture from compressed air.
Post cooling all that water is still in the air line.
Cooling condenses lots of water.
Aftercoolers are heat exchangers for cooling the discharge from a air compressor.
The compressed air travels through either the spiral finned tube coil or a plate fin coil design of the aftercooler while ambient air is forced over the cooler by a motor driven fan.
