Compression Type Air Dryer

In this type Compressed air, directly from Air compressor discharge is taken to Air dryer inlet through insulated pipelines, at 120 deg C(minimum) temperature. This hot air is passed through one drying vessel where saturated desiccant is regenerated by this hot air. After picking up moisture from desiccant bed, the air is cooled in an intermediate cooler. Here moisture is condensed and removed by auto drain valve. Cooled to 40oC, this air passes through the second drying vessel where balance moisture gets adsorbed and Dry air comes out. Cycle time is 4 hours regeneration & 4 hours drying.
