HOC DRYERS

HOC /NO PURGE LOSS Type Air Dryers

In HOC type dryer Compressed air is directly fed to the inlet of air dryer, at 120°C(minimum) temperature. This hot air is passed through one vessel which help in regeneration of desiccant in the tower. 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 40°C, this air passes through the second drying vessel where moisture gets adsorbed and Dry air comes out
