ACA Air cooled aftercoolers are designed to reduce compressed air temperature and water vapour dew point in the compressed air system. High efficiency axial fan forces ambient air over the heat exchanger copper tubes supported by aluminium fins, which provides the necessary cooling effect. The compressed air is cooled down to approximately 10°C above ambient temperature. A cyclonic separator then discharges the resulting condensate from the system. ACA aftercoolers ensure the maximum performance and protection of all equipment, such refrigeration dryers, adsorption dryers and filters, positioned downstream of this unit.

ACW Water-cooled aftercoolers have been designed to reduce compressed air temperature (thus water vapour content) in compressed air systems. Hot compressed air/gas passes through the tubes. Cooling water passes around the tubes in counter flow. A cyclonic separator then discharges the resulting condensate from the system.
