Without aftercooler, a 5,7 m3/min compressor operating at 7 bar introduces 170 liter of water into the compressed air system each day.Contracor® compressed air aftercoolers ACE and ACP are designed to cool the air to within 2.7°C to 11°C of ambient air temperature. As the compressed air cools, up to 70% of the water vapor present condenses to a liquid and can be removed from the system.CS type moisture separator installed at the discharge of the aftercooler removes most of the liquid moisture and solids from the compressed air.
