Operation of the ADX-series adsorption dryer

Phase 1 Tower (1) is in the drying cycle. Moist air flows out of the compressor via the bottom shuttle
valve (A) into the tower (1).
The pressure in the tower (1) rises to the compressor’s working pressure. The drying agent in
the tower (1) removes moisture from the inflowing compressed air. The dried compressed air
is fed through the directional control valve (B) into the compressed-air system.
Tower (2) is in the regeneration cycle. A small amount of dried compressed air (E) (purge air)
is fed through the tower (2). The blow out valve (C) is opened and the purge air together with
the moisture accumulated in the tower (2) is discharged through the blow-out valve and the
silencer.
Phase 2 The towers alternate functions in a 10-minute cycle. The blow-out valve (C) of the tower (2) is
closed, and the blow-out valve (D) of the tower (1) is opened.
The shuttle valve (A) switches simultaneously, and the moist air flows out of the compressor
into the tower (2) that is switching into the drying cycle. Tower (1) switches into the
regeneration cycle and discharges the accumulated moisture.
