HRE Series Dual Tower Heat Regenerative Desiccant
Air Dryers
Altec AIR’s HRE Series Heat Regenerative Desiccant Air Dryers apply a regulated amount of dried process air, which has been heated by way of a low watt density heater, down through the desiccant bed (counter current). This heated purge air is then exhausted to atmosphere, removing the water vapor that had adhered to the desiccant during the previous cycle.

HBP Series Dual Tower Heat Regenerative Desiccant
Air Dryers
Altec AIR’s HBP Series Heat Regenerative Desiccant Air Dryers also use heated air to regenerate the off-line tower. Additionally, a high-efficiency packaged blower assembly directs heated atmospheric air counter current through the desiccant bed, removing the water vapor collected from the previous drying cycle. Dew point spikes or heat bumps are mitigated by enabling the auxiliary cooling / stripping feature that uses a small percentage of dry process air (1.7%)
