The DD-900 high capacity desiccant dehumidifier performs exceptionally well when used in cooler climates (down to sub zero temperatures), or when a low dew-point, deep drying or low humidity levels are required.

    The Ebac DD-900 desiccant dehumidifier is manufactured from a high grade stainless steel, ensuring a rust free product when used in the severest environment. The spigot connectors allow quick and easy installation and its high efficiency patented PPS Rotor ensures effective drying. The DD900 low temperature desiccant dehumidifier is a rugged unit that incorporates a high capacity Resistive Heater to ensure 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, i.e.; high efficiency drying, deep drying, or high extraction. Facility for an external humidistat allows remote control of the drying cycle. The DD900 features 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. The DD900 rotor is washable, and designed for high performance and long life.


    Features of the Ebac DD900 Low Temperature Desiccant Dehumidifier

    • Stainless Steel Construction - Ensures a rust free product when used in even the most severe of applications. Spigot connectors allow quick and easy installation.
    • Electronic Controls - In addition to the hours run meter, which shows the units running time, an ammeter is also incorporated in order to monitor the units drying effectiveness.
    • High Capacity Resistive Heater - Ensures maximum drying is immediately reached and constantly maintained while the unit is running.
    • Remote Humidistat Facility - Can quickly and easily be connected for automatic operation and control.
    • Low Temperature Operation - Works effectively in sub zero temperatures down to -4°F (negative four degrees Fahrenheit).
    • Dual Inlet Air Filters - The DD900 desiccant dehumidifier has two separate filters. One in the "process" air inlet and one in the "reactivation" air inlet, used to clean the air entering the dehumidifier.
    • Rubber Anti-Vibration Feet
    • Auto/Manual mode selection

    NOTE: The wet air outlet from the desiccant dehumidifier must be exhausted to outside of the room being dried by means of a suitable duct. All duct connections to the dehumidifier have been designed for connections to standard size ducts. The dry air outlet is also provided with a means of attaching a duct. This can be used to direct the air towards more severe damp patches.

    Ideal applications for the DD900 Desiccant Dehumidifier include Offices - Shops - Restaurants - Warehouses - Basements - Factories - De-Flooding - Pharmaceutical - Defense Industry - Confectionery - Laboratories - Medical - Food Industry - Agriculture - Cold Stores - Hospitals - Hotels - Stadiums - Ships

    How Does Ebac DD-900 Desiccant Dehumidifier Work?

    How a desiccant dehumidifier worksDesiccant operation is simplistic yet extremely effective and reliable. Air (Process Air) is drawn into the dehumidifier, where it 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.
