The Heat of Compression (HOC) dryers are No-Purge Loss type dessicant dryers based
on adsorption principle. The hot air from the Compressor at min 120 deg C and higher
temp, is used directly for regeneration of the desiccant. After regeneration, this
air is cooled down to 40 deg C and then it is dried in second tower. Thus, the use
of heaters is eliminated. For eg. in the 6+6 Hrs. Cycle the hot air is fed for regeneration
for 4 Hrs. and for balance 2 Hr. a changeover takes place where the air is first
cooled in cooler, then dried and before going to the outlet, cools the regenerated
desiccant bed, thus bringing it down to ambient temperature. This cycle is reversed
for the next 4Hrs. where the Adsorber drying the air in the previous cycle goes
for regeneration and vice versa.
It’s having least running cost with best quality of air.
Salient Features:
- Having least running cost
