HEAT GENERATED  Desiccant Externally Heated Desiccant Air Dryer


Heat of Compression Air Dryers

     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.
