In this Dryer the inlet air Temp is 40 to 45 Deg C. and this air we will goes upto 180 Deg C. with the help of external Heater. Internally Heated Dryer is an improvised version of heatless dryer where purge air loss is very low due to regeneration is achieved by dry air at low pressure and at high temperature. To achieve this heaters are provided to heat the purge air to around 180 Deg C, which enhances its moisture carrying capacities. This hot purge air at low pressure is passed through the desiccant bed to regenerate with small quantity of purge.
- Saving in purge air loss.
- Dew point upto (-) 80 Deg C to (-) 85 Deg C (atm) can be achieved.
- Compact design.
- Simple operation
- Most economical in the range from 250 CFM – 900 CFM
- Advanced Version of Desiccant Dryer with Saving in purge air loss
