Ebac DD700 10550GR-US Desiccant Dehumidifier 220V 3ph – 231 PPD, -4°F, 170 lbs
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.

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.
