Ebac DD700 Desiccant Dehumidifier – Model 10551GR-US (460V, 3-Phase)

The Ebac DD700 (10551GR-US) is a 231 PPD industrial desiccant dehumidifier running on 460V, 3-phase at 10A and 7.5 kW. Its washable PPS rotor with 82% active silica gel moves 410 CFM of process air and 95 CFM of regeneration air through 5" and 4" duct connections. Operating range is -4°F to 104°F, and at 170 lbs and 28" × 23" × 40" it is the most portable unit in Ebac's DD desiccant series — sitting between the DD900 (364 PPD) and the entry-level desiccant models.

DD700 10551GR-US – Key Specifications and Features

  • Extraction rate: 231 PPD (typical conditions)
  • Process airflow: 410 CFM, 5" duct connection
  • Regen airflow: 95 CFM, 4" duct connection
  • Electrical: 460V, 3-phase, 60 Hz, 10A, 7.5 kW
  • Operating temperature: -4°F to 104°F
  • Rotor: washable PPS with 82% active silica gel
  • Construction: stainless steel
  • Control: auto/manual with remote humidistat connection
  • Monitoring: integrated ammeter and hour meter
  • Dimensions: 28" W × 23" D × 40" H
  • Weight: 170 lbs

Where the Ebac DD700 Performs

Pharmaceutical labs and electronics assembly areas that require sustained low dew points use the DD700 where the DD900's larger airflow would be oversized for the space. Cold storage facilities in the 10,000–20,000 sq ft range specify it as a primary unit operating year-round at or below freezing — conditions that eliminate refrigerant dehumidifiers entirely. Marine installations with 460V ship power use its stainless steel housing because the material resists salt-air corrosion in ways that painted steel cannot. At 170 lbs and 40" tall, the DD700 is the most portable of the DD desiccant series, fitting through standard industrial doorways without disassembly.

DD700 vs. DD900 vs. DD1200 – Selecting the Right Ebac Desiccant Unit

All three Ebac DD units share the same desiccant technology and -4°F operating floor. The DD700 (231 PPD, 410 CFM process air) is the mid-range unit, suited for moderate-load environments with 460V 3-phase power draws of only 10A. The DD900 (364 PPD, 530 CFM) handles larger zones at 13A/460V. The DD1200 (562 PPD, 705 CFM) is the highest-capacity unit in the series at 15A/460V. Selecting between them is a function of zone volume, target dewpoint, and available circuit amperage.

Frequently Asked Questions

What is the extraction rate of the Ebac DD700 10551GR-US?
The DD700 10551GR-US extracts 231 PPD under typical desiccant conditions. This is the mid-range Ebac DD unit — above the entry-level capacity but below the DD900 (364 PPD) and DD1200 (562 PPD).
What are the electrical requirements for the DD700 10551GR-US?
The 10551GR-US requires 460V, 3-phase, 60 Hz at 10A (7.5 kW). This is the lowest amperage draw in the Ebac DD series, making it compatible with 15A circuits in most 460V industrial distribution panels.
What is the minimum operating temperature of the Ebac DD700?
The DD700 operates down to -4°F — identical to the DD900 and DD1200. Desiccant adsorption continues independently of ambient temperature, unlike refrigerant dehumidifiers that lose efficiency below 50°F.
How does the DD700 compare to the DD900 and DD1200?
All three share -4°F operation and desiccant technology. The DD700 extracts 231 PPD at 410 CFM/10A (460V); DD900 extracts 364 PPD at 530 CFM/13A; DD1200 extracts 562 PPD at 705 CFM/15A. Select based on zone volume and available circuit capacity.
What duct sizes does the DD700 10551GR-US require?
Process air uses a 5" duct at 410 CFM; regeneration air uses a 4" duct at 95 CFM — the same duct sizes as the DD900 and DD1200, simplifying installation planning when multiple units are used in a facility.
What does the 82% active silica gel content in the PPS rotor mean?
The 82% active silica gel figure is a material density specification for the PPS (polyphenylene sulfide) rotor. Higher silica content means more moisture adsorption sites per unit of rotor volume, directly increasing extraction capacity per cycle. The rotor is also washable, allowing maintenance cleaning without replacement.
