Working Principle of Heatless Air Dryer


In Heatless Air Dryer two adsorber towers filled with Activated Alumina / Molecular Sieves to absorb the moisture present in the wet compressed air. Wet incoming compressed air or gas is passed through an adsorber tower where moisture is adsorbs to achieve better dew point. The dry air comes through the top of tower. After some time of operation activated alumina needs regeneration. Reactivation or regeneration of activated alumina is necessary to drive off the adsorbed moisture and to restore its absorptive capacity. This is accomplished via purging the adsorbent by dry air or gas at atmospheric pressure and temperature in reverse direction. The purge loss in around 10% of dry air. Changeover will take place through PLC/Timer and continuous dry air will be received at outlet.

DRYER WITH ONLINE DEW POINT TRANSMITTER:-

PURGELOSS of 10% is reduced up to 5% by integrating online dew point transmitter to the Sequential programmer. Drying Tower changeover takes place when dew point goes down the desired limit which results in huge saving of purge air.
