EBAC DD700 Industrial Desiccant Dehumidifier, 231 Pints/Day, 460V, 7.5kW
High-Capacity Desiccant Dehumidification
The EBAC DD700 is an industrial desiccant dehumidifier designed for high-capacity moisture removal, low humidity control, deep drying, and condensation management. This specific configuration is identified by manufacturer part number 10551GR-US and operates at 460V, 3-phase, 60 Hz.
The DD700 provides a high extraction setting of 231 pints per day at 27°C and 60% relative humidity. It also provides High Efficiency and Deep Drying settings of 184 PPD and 205 PPD respectively under the same stated test conditions.
Desiccant Adsorption Technology
The DD700 uses a silica-gel desiccant rotor to remove moisture from process air. Moist air is drawn into the dehumidifier and passed over the rotating wheel, where moisture is absorbed by the silica gel. The resulting dry air is then discharged from the unit.
A separate regeneration air stream is heated before passing through the regeneration section of the rotor. Moisture collected by the desiccant is released into this air stream and exhausted as hot, wet air outside the area being dried. This continuous adsorption and regeneration process provides moisture removal without conventional condensate collection.
460V Three-Phase Operation
The 10551GR-US configuration operates at 460V, 3-phase, 60 Hz, with a listed power rating of 7.5kW and current rating of 10A. The exact 10551GR-US spare-parts documentation also identifies this model as DD700, 460V, 3-phase, 60Hz.
Three Drying Settings
An electronic thermostat and variable-speed EC fans allow the DD700 to be operated in High Extraction, High Efficiency, or Deep Drying modes. At 27°C and 60% relative humidity, the manufacturer lists 231 PPD for High Extraction, 184 PPD for High Efficiency, and 205 PPD for Deep Drying.
High Airflow Capacity
The DD700 provides a maximum process dry-air airflow of 883 CFM, nominal process dry-air airflow of 410 CFM, and nominal regeneration wet-air airflow of 95 CFM. The process air outlet is 8 inches and the regeneration air outlet is 6 inches.
Variable-Speed EC Fans
Two EC high-efficiency fans with variable-speed operation provide flexibility for installation and commissioning. The fan system works with the electronic thermostat to support the selected drying preference.
Compact Upright Design
The DD700 has an upright design intended to accommodate space-restricted areas. The unit measures 40 inches high x 28 inches wide x 23 inches deep and weighs 170 pounds.
PTC Heater and Filtration
The DD700 incorporates a high-capacity PTC heater to support the regeneration process. Process and regeneration air filters are included, along with high-temperature safety cut-outs.
Humidity Control
The DD700 includes a remote humidity sensor facility and can be used with optional humidistat accessories. Available accessories include a rotary humidistat, humidistat with internal sensor, and humidistat with external sensor.
Operating Temperature Range
The manufacturer specifies an operating temperature range of -4°F to 104°F. Desiccant dehumidification is suited to cooler environments and applications requiring low dew points, deep drying, or low humidity levels.
