HD 4-96 / TD 8-650: Water- and air-cooled after-coolers

Atlas Copco’s after-coolers, whether cooled by water (HD) or air (TD), are reliable, require minimum maintenance and provide trouble-free protection against the costly effects of water in your system. Both types deliver air into the air-net at a temperature suitable for most types of air dryers. High cooling efficiency is combined with low energy consumption.

HD water-cooled after-coolers use a bundle of stainless steel tubes to cool the air, with the cooling water and the compressed air flowing in opposite directions. The cooling tubes are reeled inside to create turbulence for more rapid cooling of the compressed air. TD air-cooled after-coolers have an aluminium block cooling element. An electrically driven fan, shielded by a protector for user safety, forces cooling air between the fins.

Customer benefits

  • Easy installation – HD and TD after-coolers are supplied complete with all necessary parts. They are compact and simple to install.
  • Energy-efficient – The negligible pressure drop effected by HD and TD after-coolers means virtually no loss of power to compressed air-driven tools, machines and pneumatic devices. Thus no extra demand is placed on the compressor and no additional energy or maintenance costs are incurred.
  • Minimum maintenance – The after-coolers are easy to dismantle for cleaning.
  • High reliability – Constructed from totally rustproof material, HD and TD after-coolers are guaranteed for a long lifetime of reliable operation.
