Internal Heat Re-activated Type
Heat Reactivated dryers are used when one needs compressed air of very low Dew point of (-)60˚C or (-)80˚C. In this design, the desiccant is regenerated at higher temperature, along with small quantity of Dry air purge. Due to purging with Dry air and thermal regeneration, residual moisture loading on desiccant becomes low and this gives very low Dew points.

External Heat Re-activated Type
External heat re-activated air dryers are bulky in size and the power consumption is almost double as compared to Internal Heat Re-activated Type Dryers. In capacities less than 500 NM3/hr these are uneconomical and not recommended. Also, since regeneration of the desiccant is by atmospheric air, these dryers give Dew Point only upto (-) 40˚C.
