Heat regeneration adsorption air dryers are used when one needs compressed air of very low Dew point of (-)60oC or (-)80o Deg C. In this design, the desiccant is regenerated at higher temperature, along with small quantity of Dry air purge. Due to purging with Dry air and thermal regeneration, residual moisture loading on desiccant becomes low and this gives very low Dew point.

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. Moisture laden purge air is then vented out to atmosphere. Automatic re-pressurizing equalizes desiccant vessels pressure before changeover. So Desiccant movement is avoided

This is the simplest type of Air Dryer with Activated Alumina Molecular sieves Drying agent. Investment wise also this is the cheapest. This design is virtually maintenance free, fully automatic, and requires no attention for years. Cold regeneration type dryers do not require any heating for re-generation and therefore are very simple in design and smooth in operation.

The purge loss is around 7.5% 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 20% if (-)800C dew point is needed. Eliminates need of costly heaters for regeneration, and also no cooling water requirement
