Desiccant Air Dryers

Our heatless Desiccant Air Dryers consist of two towers containing a specialised material that absorbs the water vapour in the saturated compressed air stream. The dryness of the product is dictated by the amount of time the saturated air remains in contact with the absorption material. When compressed air enters the system through coalescing filters, 99.999% of oil, water, and liquid contaminants are removed.

At On Site Gas Systems, our Desiccant Air Dryer features both pre-air and after-air treatment, with 1 coalescing filter for the removal of water, oil, and particles and a dust particle remover for maximum removal of contaminants. The two towers work in conjunction, with the on-line tower drying air while the off-line tower regenerates by purging the entrained moisture to the atmosphere with a stream of dry air. This dry, clean air then exits the system through a dust removal filter into your plant distribution system.

Our Desiccant Dryers provide moisture-free air down to a -40 ºC pressure dew point.
