The heatless twin tower desiccant dryer from ELGi removes moisture through absorption onto a granular desiccant bed from the air supply. Water vapour is absorbed as compressed air flows up through a packed bed of desiccant in tower 1. Meanwhile, tower two is rapidly depressurised, and dry purge air from the outlet of tower one is fed through a purge valve, expanded to near atmospheric pressure, and counter-flowed down through tower 2 to effect its regeneration granular desiccant bed. When the desiccant in tower 1 becomes saturated with water vapour, the air supply is switched back to tower two after being re-pressurised, and the cycle continues. As a default, all HLD models above 5X are provided with a dew point stretch cycle and purge optimiser.
AIRMATE DESICCANT DRYER
Brand: ELGi
ELGi’s heatless twin tower desiccant dryer efficiently removes moisture from air supplies through absorption, utilizing a cyclic process across two towers for optimal regeneration. Designed with a dew point stretch cycle and purge optimizer for models above 5X, this system ensures continuous, effective drying.
