Aftercoolers / heat exchangers for blowers

The perfect fit: Aftercoolers / heat exchangers for Kaeser blowers

Kaeser aftercoolers / heat exchangers are specifically designed for use with Kaeser blowers. They are designed for all applications requiring an upper limit on the process air temperature. In addition, it is possible to recover heat energy with aftercoolers / heat exchangers. 

Kaeser offers two cooling concepts for aftercooling:

  • For use when the ambient air is cool enough and without a water source: Air cooling (cross-flow heat exchanger, ACA series).
  • For achieving very low temperatures: Water cooling (shell and tube heat exchanger, WRN series).
The heated cooling air can be used for hall-heating purposes, while the heated cooling water can be used in water treatment systems, for example, to dry sludge.

Your advantages

  • Full energy transfer:
    Our aftercoolers / heat exchangers are specifically designed for use with Kaeser blowers. This keeps flow and pressure losses to an absolute minimum, therefore allowing all of the input energy to be available for further use.
  • The right aftercooler / heat exchanger for every need:
    We will select the perfect aftercooler / heat exchanger for your specific pressure and temperature needs from our comprehensive product range. This means greater efficiency and a longer service life.
  • Protection of temperature-sensitive bulk materials:
    Kaeser aftercoolers / heat exchangers reliably lower the air temperature. The quality of temperature-sensitive bulk materials such as baking mixes, animal feed, or plastic granules is not compromised.
