It is a heat exchanger designed & manufactured to reduce / cool the compressed air temperature to desired level, so the condensation takes place & vaporized moisture & oil in air gets converted in liquid droplets which further separated by moisture separator. The after cooler substantially reduces the moisture & oil load coming on down stream at the initial stage. The cooling media can be water or air.
