Overview
In Heatless desiccant 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 air dryer 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 desiccant dryer 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.
