 Directly from Air
compressor the Compressed air, is taken to Air dryer inlet through
insulated pipelines, at 120oC(minimum)
temperature. This hot air is passed through one drying vessel
where saturated desiccant is regenerated by this hot air. 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 40oC,
this air passes through the second drying vessel where balance
moisture gets adsorbed and Dry air comes out. Cycle time is of 4
hours regeneration & 4 hours drying. After 4 hours the
changeover of vessels takes place automatically. In regeneration
cycle heating of the bed is only for 2 hours and thereafter the bed
is cooled by Dry air. After bed cooling, Dry air is again cooled
to 40oC
in another cooler, and delivered out of unit as Dry air at 40oC
temp.

The Dryer is fully automatic with pneumatically actuated Ball/
plug valves. A sequence timer controls operation of these
valves. Desiccant used is Activated Alumina and it dries the air
up to (-)40oC Dew point.
There is considerable power saving in these type of Compressed
Air Dryers and the dew point is also better than the
Refrigerated type of Compressed Air Dryers.
Main Advantage of Heat of Compression Type Compressed air dryer
is the energy conservation and heat recovery achieved which is
being wasted in After cooler in the conventional air dryer is
now used to reactivate the desiccant.
