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

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 optional 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) Extraction rate: 231 PPD (typical conditions) Process airflow: 410 CFM, 8" duct connection Regen airflow: 95 CFM, 6" duct connection Electrical: 220V, 3-phase, 60 Hz, 20A, 7.5 kW Operating temperature: -4°F to 104°F Rotor: washable PPS with 82% active silica gel Construction: stainless steel (optional) 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, optional 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.
