Altec AIR HRE Series Dual Tower Heat Regenerative Desiccant Air Dryer - 1250 SCFM

HRE Series Heat Regenerative Desiccant Air Dryer

The HRE Series from Altec AIR utilizes a low watt density heater to warm a regulated amount of dried process air, which then flows counter-current through the desiccant bed. This heated purge air removes moisture from the desiccant and is vented to the atmosphere—ensuring continuous, reliable drying performance.

Designed with ASME/CRN approved pressure vessels and a feature-rich Pro-Logic Controller, the HRE Series provides a rugged, dependable solution for industrial applications requiring high-quality air and reliable -40°F dew point performance.
