Heat Of Compression Dryers By Delair India Pvt. Ltd

The wet hot air enters the dryer through 3 way valve (V-1), where it change the direction direct towards 4 way ball valve V-2 in heating cycle and towards 4 way ball valve thru pre cooler in cooling cycle.

Heating :
The regeneration of desiccant is carried out by hot air. This air passes through port (1-2) of 3 way valve (V-1) enters the 4-way valve (V-2) where from it is directioned to the absorber tower (ADS-1), which is in regeneration mode, through the port (3-4). The hot air heats the desiccant bed and expels the moisture present in desiccant. The air after passing through the ports (4-1) of 4-way valve (V-3) enters into the regeneration cooler (RC-1). The air gets cooled to inlet air temperature in the cooler and enters the moisture separator for moisture separation. After moisture separation, it enters into absorber tower (ADS-2) via ports (1-2) of 4 way valve (V-1) for adsorption (Drying).

Cooling :
When the desiccant gets heated up by hot air it is to be cooled upto drying inlet air temperature for effective drying.
