Ebac Industrial DD900 460V 9800W High Capacity High Efficiency Desiccant Dehumidifier 10521GR-US

Description

The DD900 is the largest desiccant dehumidifier within the EIPL range. The unit incorporates a high capacity resistive heater ensuring maximum drying is immediately reached and constantly maintained while the unit is running. The DD900 incorporates two EC fans with variable speed allowing the unit to be easily installed and commissioned in a wide variety of installations. An electronic thermostat allows the user to select the desired drying level ie, high efficiency drying, deep drying, or high extraction. Facility for an external humidistat allows remote control of the drying cycle All models incorporate a high efficiency patented PPS Rotor. This design incorporates an 82% active Silica Gel to ensure optimum performance over the equipment’s wide operating range of environments. All desiccant rotors supplied by EIPL are washable and designed for high performance / long life.

How the DD900 Works

Dehumidification is possible using two possible principles, Condensation with refrigeration style dehumidifiers and Adsorption with desiccant dehumidifiers. Desiccant dehumidifiers perform exceptionally well when used in cooler climates, or when a low dew-point, deep drying or low humidity levels are required. Since desiccant dehumidifiers do not produce water, they will work effectively down to sub zero temperatures. Their operation is simplistic yet extremely effective and reliable. Air (Process Air) is drawn into the dehumidifier, where is passes over a wheel impregnated with Silica Gel. As the air passes over this wheel, any moisture present in the air, is absorbed into the Silica Gel wheel before leaving the dehumidifier as warm dry air. The Silica Gel wheel is continually, slowly rotating, typically at three revolutions per hour. As the wheel rotates a small portion passes through the regeneration segment. During this phase a second air stream (Regeneration Air) is heated to a high temperature before passing over the wheel. Any moisture present in the wheel is released into this air stream, this hot wet air is then exhausted outside the area being dried.
