Aftercooler and Moisture Separator Explained

The aftercooler and moisture separator handle the bulk of the water in compressed air before the dryer polishes it.

How the Aftercooler Works

Hot discharge air is cooled so water vapour condenses, with air-cooled or water-cooled designs matching site conditions.

Separating the Water

Centrifugal or coalescing separators remove the condensed droplets, protecting dryers and downstream equipment.

Why Bulk Removal Matters

Removing most moisture early reduces the load on the dryer, improving drying performance and lowering energy use.
