Hankison’s Air-cooled Aftercoolers are engineered to maximize heat transfer with minimum pressure drop which results in cool, compressed air that can be used to precondition air for further filtering and drying or space heating, by reclaiming normally wasted hot air.Economical, air-cooled aftercoolers use ambient air to lower compressed air temperature and can be sized to cool the compressed air within 5°F to 20°F (3°C to 11°C) of the ambient air temperature.
