Ebac DD700 Desiccant Dehumidifier – Model 10550GR-US (220V, 3-Phase)

The Ebac DD700 (10550GR-US) is the 220V, 3-phase variant of Ebac's 231 PPD mid-range desiccant dehumidifier. Drawing 20A at 220V versus 10A at 460V, it delivers identical 7.5 kW output, 410 CFM process airflow, and -4°F minimum operating temperature. The stainless steel housing, washable PPS silica gel rotor, auto/manual controls, and integrated ammeter/hour meter are shared across both voltage variants. Selection between the 220V and 460V models is determined entirely by the site's power distribution.

DD700 10550GR-US – Key Specifications and Features

  • Model: 10550GR-US (DD700, 220V 3-phase)

  • 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 220V Performs

International facilities with 208–240V 3-phase service and older North American plants without 460V distribution use the 10550GR-US. The 220V model draws 20A versus 10A at 460V for the same 7.5 kW output, which requires a 25A or larger circuit by code. Cold storage operations in international markets where 220V 3-phase is the standard industrial supply specify this variant. The performance profile — 231 PPD extraction, -4°F minimum, stainless housing — is identical to the 460V model.

Choosing Between DD700 220V and 460V

The 10550GR-US (220V) and 10551GR-US (460V) are electrically equivalent in performance: 7.5 kW, 231 PPD, 410 CFM. At 220V, 20A is required; at 460V, only 10A. Higher voltage operation reduces conductor cross-section and line losses over long cable runs — which is why 460V is the standard in large industrial facilities. For sites with 208–240V 3-phase service, the 220V model is the correct specification with no performance penalty.

Frequently Asked Questions

What is the difference between the Ebac DD700 10550GR-US and 10551GR-US?
Both are the same DD700 desiccant dehumidifier with 7.5 kW output and 231 PPD extraction. The 10550GR-US runs on 220V 3-phase at 20A; the 10551GR-US runs on 460V 3-phase at 10A. Select based on available site power distribution.
What is the current draw of the DD700 10550GR-US at 220V?
The 10550GR-US draws 20A at 220V 3-phase. Circuit protection and wiring should be sized for 25A or larger per electrical code — double the amperage of the 460V model for the same 7.5 kW output.
What is the minimum operating temperature of the DD700 10550GR-US?
The 10550GR-US operates down to -4°F — identical to the 460V model. Silica gel adsorption is thermally independent and maintains extraction performance at sub-zero temperatures where refrigerant dehumidifiers fail.
What process airflow does the DD700 produce?
The DD700 moves 410 CFM of process air through a 5" duct, and 95 CFM of regeneration air through a 4" duct. These duct sizes apply to both the 220V and 460V models.
What is the extraction rate of the DD700 10550GR-US?
The 10550GR-US extracts 231 PPD under typical desiccant operating conditions — identical to the 460V model. This positions the DD700 between the DD900 (364 PPD) and below the DD1200 (562 PPD) in Ebac's desiccant lineup.
Why specify the 220V 3-phase DD700 instead of the 460V model?
Specify the 10550GR-US for facilities with 208–240V 3-phase distribution, including international sites and older North American industrial buildings. The 460V model (10551GR-US) is preferred for large facilities with 460V standard distribution, as it draws only 10A versus 20A for the same 7.5 kW output.
