ABC – Air-Cooled Aftercoolers

WBC – Water-Cooled Aftercoolers

Compressed air flows into the WBC aftercooler and enters the heat exchanger coils. Cooling water flows over the coils in the opposite direction to offer the greatest possible heat exchange. As the air cools, the moisture condenses. When the air reaches the water separator, centrifugal motion causes the condensation and other contaminants to hit the cylinder walls and drip away to the drain.

Features & Benefits

  • Versatile Design – The unit can be mounted in a vertical or horizontal configuration. Standard models are made of copper tubes and steel shells, while there are options available that are made from cupronickel for sea water and stainless steel for high pressure gases. This means that there is a unit for virtually every application.
  • Shell and Tube Heat Exchanger – The hot compressed air flows through the tubes while the cooling water flows in the opposite direction around the tubes. The result is cooler air with limited pressure drop.
  • High Efficiency Separator – Installed at the base of the aftercooler, it will remove greater than 99% of the condensate.
  • Approved Design and Construction – Designed, built and tested to any of the major international pressure vessels codes.
  • Reduced Approach Temperature – The superior design of the WBC aftercoolers ensures that the compressed air will be cooled to 10°C above the cooling water temperature. This outstanding heat exchanger performance, combined with the high efficiency of the separator, ensures the maximum removal of moisture from the compressed air.
  • Reduced Water Consumption – The cooling water consumption can be adapted to your needs.
  • Resistant to Thermal Expansion – WBC aftercoolers are designed to withstand high temperatures. This ensures problem free service under all operating conditions.
