After coolers

Compresed Air Insitu is an authorised distributor for Southern Cross Compressors who offer a high quality air compressor aftercooler range that will efficiently remove condensate (water) from compressed air to protect your system. Air compressor aftercoolers provide the lowest capital and running cost in removing condensate from compressed air.

Air compressor Aftercooler Process

Compressed air is cooled through either an air cooled or water cooled heat exchanger forcing moisture entrapped in the air to condense. The air is then channeled through an efficient condensate separator that spins out a large portion of the condensate.aftercoolers air compressors

Aftercoolers can be supplied as an aftermarket accessory for your existing compressor set and can be matched to your reciprocating or rotary screw compressor.Many new compressors have an air compressor aftercooler internally fitted, however internally fitted aftercoolers are generally under-sized for Australia’s often extreme conditions. It is wise to ‘add on’ aftercooling and is a good way to address problematic water issues in existing systems.

What are the benefits of having an air compressor aftercooler?

Aftercoolers are the cheapest form condensate removal (water vapour that has condensed back to water) from compressed air. Aftercoolers are not normally needed on new compressors as most new machines are fitted with them as standard.

Aftercoolers operate similar to a radiator in your car. An air compressor aftercooler cools compressed air to condenses any moisture back to water. Water is then removed by a condensate separator. Delivering cool, dry air to your factory is required to reduce potential damage to your equipment or the products you are manufacturing.


An air compressor aftercooler makes the separation and removal of water easy.

Benefits of having an air compressor aftercooler in your compressed air system:

  •  Reduces moisture build up in air lines
  •  Reduces rust inside air lines
  •  Reduces rust inside air tools
  •  Reduces product spoilage
  •  Reduces potential for water to wash out lubricants from tools

Aftercoolers typically remove about 70% of the water vapour from compressed air, if they are correctly sized to do the job. To size an air compressor aftercooler properly a number of considerations and readings must be taken from the proposed site.
