Principle of Operation
In Heat of compression air dryers, we use hot
compressed (120 deg C to 180 deg) air as regeneration
medium for regenerating the saturated desiccant
without any additional heater. Hence running cost for
HOC Dryers are virtually Nil. The hot air which is used
for regeneration is cooled by after cooler to bring
down the temperature to 45 deg C and less, is fed
into another tower for Adsorption.
These Dryers are working on 8 + 8 Hrs cycle. In 8
Hrs. Cycle the hot air is fed for regeneration of
desiccant bed for 4.30 Hrs and remaining 2.30 Hrs.
a changeover takes place where the air is first cooled
in an after cooler to bring down the temperature to
less than 45 deg C, then it is dried. Before going to
the outlet, It cools the regenerated desiccant bed,
thus bringing it down to ambient temperature. This
cycle is reversed for the next 8 Hrs.
