Heatless Air Dryer

Compressed air coming from the Receiver containing solid, liquid & vapour contaminants enters the Dryer through the Pre-filter (where solid & liquid contaminants are removed). It then passes through Oil Removal Filter and enters into Adsorption Tower A1 through a 3-way valve (CV-1) where it gets dried and then passes out of the Dryer through the After-filter. A part of this dry air passes through Tower A2 through the Purge Control Valve, where it picks up the moisture from the adsorbent thereby regenerating it and making it ready for the adsorption cycle. The purge air exhausts out of the Dryer through Purge Exhaust Valve (CV-2) of Tower A2.
