EBAC DD900+ Industrial Desiccant Dehumidifier
The EBAC DD900+ Industrial Desiccant Dehumidifier is a high-capacity, PLC-controlled drying solution engineered for demanding industrial applications requiring deep drying and ultra-low humidity control. Delivering up to 364 PPD of moisture extraction, the DD900+ is designed to perform reliably in extreme environments, including sub-zero temperatures down to -4°F where refrigerant-based systems fail.
Using advanced adsorption technology, the DD900+ draws process air across a slowly rotating wheel impregnated with 82% active Silica Gel. Moisture is absorbed at the molecular level before the air exits as warm, dry air. A secondary regeneration air stream heats a section of the wheel to release captured moisture, which is exhausted as hot, wet air outside the conditioned space. Because the unit does not rely on condensation, there is no freeze risk in cold environments.
The “+” version enhances the standard DD900 platform with a fully integrated PLC control system, including filter cleanliness monitoring, belt tension monitoring, and compatibility with EBAC energy-saving Pre-Heat and Post-Cool modules. Dual EC variable-speed fans allow precise commissioning for various installations, while high-capacity PTC heaters ensure immediate and continuous maximum drying performance. Built from epoxy powder-coated steel (stainless steel options available), the DD900+ is engineered for durability in the most severe industrial conditions.
Application
Desiccant dehumidifiers like the DD900+ are essential wherever humidity must be reduced to prevent corrosion, mold growth, and condensation, or where controlled low humidity is required during manufacturing, packaging, or storage of hygroscopic materials. Ideal for cold storage, industrial plants, pharmaceutical production, and corrosion-sensitive environments.

- Designed for industrial use (not residential applications)
Methods of Dehumidification
Dehumidification is achieved using either condensation (refrigeration-style systems) or adsorption (desiccant systems). Refrigerant models lose efficiency at lower temperatures and may freeze. Desiccant dehumidifiers, such as the DD900+, excel in cooler climates and deep drying applications because they do not produce liquid water. This allows continuous operation in sub-zero conditions without performance loss.
