Air Blast Oil Cooler

Air Blast Oil Cooler

Functions of compressed air after coolers : –

Coolers are usually sized with a CTD (Cold Temperature Difference) of 5°F, 10°F, 15°F or 20°F (2.7°C, 5.5°C, 8.3°C, or 11°C). This means that the compressed air temperature at the outlet of the aftercooler will be equal to the cooling medium temperature plus the CTD when sized at the specified inlet air temperature and flow.

Recommended location of after coolers : –

The aftercooler should be located as close as possible to the discharge of the compressor.

Types of after coolers

There are two basic types of air aftercoolers:

The type of aftercooler you choose depends on your preference and requirements.

Compressor manufacturers may include aftercoolers within the compressor package. In general these compressors are referred to as integral aftercoolers. A stand-alone or freestanding aftercooler is a separate unit installed downstream of the compressor.

Maintenance requirements : –

Aftercooler (water-cooled): Routinely inspect, clean, check approach temperature, pressure drop and monitor water quality.

Aftercooler (air-cooled): Inspect and clean on a regular basis. Check drain valves daily.

Proper maintenance will keep the aftercooler efficient. A dirty aftercooler results in both warmer air temperatures and increased pressure drop.
