  • Product Overview

    The Ebac DD400 Desiccant Dehumidifier is the largest desiccant dehumidifier within the Ebac Industrial Products DD Series of desiccant dehumidifiers. It’s compact, rugged, and lightweight design facilitates easy transportation by one person and is easily accommodated within space restricted areas. The DD400 dehumidifier incorporates a PTC Heater ensuring maximum drying is immediately reached and constantly maintained while the unit is running. 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. Manual / Automatic control is a standard feature within the DD range of desiccant dehumidifiers, and a remote humidistat can quickly and easily be connected for automatic operation and control. The Ebac DD400 Desiccant Dehumidifier is made from a high grade stainless steel, ensuring a rust free product when used in the most severe of applications. The spigot connectors allow quick and easy installation. All models incorporate a high efficiency patented PPS Rotor. This design incorporates an 82% active Silica Gel to ensure optimum performance over the equipments wide operating range of environments. All desiccant rotors supplied by Ebac are washable, and designed for high performance and long life.

    How Desiccant Dehumidifiers Work

    Desiccant dehumidifiers perform exceptionally well when used in cooler climates, or when a low dewpoint, deep drying or low humidity levels are required because they dehumidify through adsorption. 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.

    The DD400 is of the desiccant wheel type of dehumidifiers designed to dry air by passing a large volume of air, the “process” air through a slowly rotating Silica gel rotor. Silica gel is a hygroscopic material that absorbs moisture direct from the air. As the air passes through the rotor, the humidity of the air is reduced, while the moisture content of the rotor is increased. A smaller volume of air, the reactivation air, is heated by an internal heater and passes through a portion of the rotor in the opposite direction. As this heated air passes through the rotor it will “reactivate” it by removing the moisture content from the silica gel material. The reactivation air will leave the humidifier as warm, moist air and must be vented to outside of the building. Continuous circulation of the room air through the dehumidifier unit gradually reduces the relative humidity in the room.

    Amount of Water Removed

    The amount of water removed by the Ebac DD400 Desiccant Dehumidifier depends on the temperature and the relative humidity in the area the dehumidifier is being used. Please refer to the chart to the right and the graph below to determine the amount of water that will extracted from the air based on your specific conditions.
