In small air systems 20 hp it s common to see the receiver tank used to separate and collect liquids.
Air compressor line cooler.
If the temperature at the discharge port exceeds 300 degrees fahrenheit the refrigerant oil and adjacent mechanisms.
This fellow measured his compressor outlet.
The compressed air enters the air cooled aftercooler.
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.
Post cooling all that water is still in the air line.
Make no mistake a cooler alone does not yield high quality compressed air.
Low cost air dryer water separator.
Cooling condenses lots of water.
Air cooled aftercoolers use ambient air to cool the hot compressed air.
Removing the liquid requires a moisture separator and a drain valve.
They use either air or water and are an effective means of removing moisture from compressed air.

Aftercoolers are heat exchangers for cooling the discharge from a air compressor.
