Atlas Copco - HD Water-cooled after coolers    

Atlas Copco HD water-cooled after coolers are designed to combine a high level of cooling with economic water consumption. The air leaving the compressor is cooled in a group of stainless steel tubes, with the cooling water and the compressed air flowing in opposite directions. A water separator is provided with the cooler as standard. A thermometer indicates the temperature of the discharged air.

The cooling tubes are fitted with fins which give a larger surface area to improve heat transfer and create turbulence for more rapid cooling of the compressed air. The water is deflected by baffles to increase the cooling effect.
