INTERNALLY HEAT REACTIVATED AIR DRYER
DESCRIPTION OF THE INTERNALLY HEAT REACTIVATED AIR DRYER
The Internally Heat Reactivated Air Dryer is a simple alternative for medium & bigger capacities where Heatless Dryers become uneconomical due to heavy purge losses. In this type of Dryer, the regeneration is accomplished with a very small portion of dried air/gas. This is circulated in the tower duly filled with desiccant and embedded with heating elements. The advantage of this type of dryer is that purge loss is reduced to almost 3 – 5%, and dew points up to (-) 80 °C can be achieved.
This is an improved version of the Heatless Dryer where purged air loss is low due to the fact that regeneration is achieved by dry air at low pressure and at high temperature. To achieve this heaters are provided in each tower 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 the Activated Alumina.
