Heatless compressed air dryer (drier) is the simplest form of desiccant type (activated alumina / molecular sieves) air dryer (drier) for achieving a dew point of -40°C or better for compressed air systems. It is the simplest design, which is virtually fully automatic and maintenance free. These heats less type dryers do not require any heating for re-generation and therefore are very simple in design and smooth in operation. 
In heat less dryers, two vessels are filled with desiccant, which cycle automatically, producing dry air continuously. In these units, wet air enters the bottom of one vesseland passes upwards through the desiccant bed where the moisture is adsorbed. The dry air comes out from the top. 
A small portion of dry air is passed downward through the desiccant bed in the second vessel, which is under re-generation. Then the moisture laden purge air is vented out to atmosphere. The purge loss is around 10-15 % of the total air flow. 
At preset interval, the vessels changeover automatically and dry air is available continuously, without any surges, the purge air requirement is around 10-15 % if (-) 400C dew point is needed from heatless type Air Dryers.
