HMW series desiccant dryers use electrical heaters inside of the desiccant bed for regeneration of the saturated desiccant. The direct contact of the finned heater tubes with the desiccant bed makes most efficient use of the regeneration energy.
A small part of the compressed air flow removes the moisture and cools down the desiccant. No ambient pollution or moisture affects the regeneration process. A parallel drying phase during cycle change-over eliminates any temperature or dew point fluctuation. With the optional Energy Management System device EMS, the standard drying time per receiver of 4 hours can be prolonged to a maximum of 20 hours, resulting in energy savings of up to 80%.
