Ebac DD700 Industrial Desiccant Dehumidifier
The Ebac DD700 Desiccant Dehumidifier offers extreme moisture extraction in a compact, rugged, and lightweight package. As part of Ebac's DD Series of desiccant dehumidifiers, this model is ideal for reducing humidity in industrial areas in order to prevent corrosion, mold growth, and condensation as well as to maintain low-humidity conditions every day. Ebac desiccant dehumidifiers are exceptional performers in cooler climates or when a low dew point, deep drying, or low humidity levels are required. The DD700 removes up to 231 pints of moisture per day at in AHAM conditions and operates successfully in temperatures as low as -4 degrees F.
How Ebac Desiccant Dehumidifiers Work
Industrial desiccant dehumidifiers are different than conventional refrigerant dehumidifiers in that they dehumidify through adsorption instead of condensation. During operation, air is drawn into the dehumidifier where it passes over a wheel impregnated with silica gel. As air passes over this wheel, any moisture that is present in the air is absorbed into the silica gel wheel before leaving the dehumidifier as warm, dry air.
This silica gel wheel continuously and slowly rotates at 3 revolutions per hour. As the wheel rotates and circulates air, a small portion of air passes through the regeneration segment. "Regeneration" air is heated to a high temperature before passing over the wheel. Any moisture present in the wheel is then released into this air stream, and the hot wet air is then exhausted outside the area being dried. Overtime, this continuous circulation gradually reduces the relative humidity of a room.
