The EBAC DD900 Desiccant Dehumidifier is a high-capacity industrial humidity control system designed for demanding commercial and manufacturing environments. Using advanced desiccant rotor technology, it effectively removes moisture even in cold conditions down to -4°F, making it ideal for facilities where refrigeration-based dehumidifiers are less effective.

Available in 220V and 460V three-phase configurations, the DD900 delivers up to 364 PPD of moisture removal while offering multiple operating modes including High Extraction, High Efficiency, and Deep Drying. Its electronically controlled operation, EC high-efficiency fan, adjustable thermostat, and energy-efficient PTC heaters provide reliable, energy-conscious performance for warehouses, manufacturing plants, storage facilities, pharmaceutical production, food processing, and other humidity-sensitive applications.

Designed for continuous industrial operation, the DD900 features remote humidity sensor capability, variable fan speeds, status indicators, process and regeneration air filters, and integrated safety controls to ensure dependable performance in challenging environments.
