Inter Cooler & After Cooler

Inter Cooler

An intercooler is a mechanical heat exchanger that removes the heat from the compressed air generated by an air compressor. It is fitted in the intermediate stages of the compressor.

An intercooler permits the supply of more air to the compressor by increasing the air?s density which in turn boosts the overall efficiency of the compressor. An efficient intercooler will restore the temperature of compressed air to near environmental levels.

After Cooler

A standard aftercooler unit is composed of tubing (containing water or air) and fins that help it achieve cooling. When in operation, ambient air is pulled into the aftercooler to help remove moisture from the compressed air by condensation while reducing process temperatures to satisfactory levels. Compressed air aftercoolers are manufactured as either water or air-cooled variants.

For air-cooled compressed air aftercoolers, ambient air is directed over tubes containing hot compressed air to remove generated heat in a heat exchange process. In a water-cooled version (also called an air-to-water cooler), water is channeled through tubes running alongside compressed air pipes to achieve cooling.
