Ebac DD900 10520GR-US Desiccant Dehumidifier 220V 3ph – 364 PPD, -4°F, 198 lbs
Ebac DD900 Desiccant Dehumidifier – Model 10520GR-US (220V, 3-Phase)
The Ebac DD900 (10520GR-US) is the 220V, 3-phase variant of Ebac's 364 PPD industrial desiccant dehumidifier. Electrically identical to the 460V model in kW output (9.8 kW) but drawing 26A at 220V versus 13A at 460V, it fits sites with 220V 3-phase distribution rather than 460V. The same washable PPS silica gel rotor, 530 CFM process airflow, stainless steel housing, and -4°F minimum operating temperature apply across both voltage variants.

Where the Ebac DD900 220V Performs
International facilities and North American plants with 208–240V 3-phase service use the 10520GR-US instead of the 460V model. The electrical performance is identical — 9.8 kW total consumption and 364 PPD extraction — but the higher current draw (26A vs. 13A) requires appropriately sized wiring and overcurrent protection. Cold storage operations running 220V distribution, pharmaceutical facilities in international markets, and marine installations on 220V ship power all specify this variant. The same -4°F operating floor, stainless construction, and 82% silica gel rotor apply regardless of voltage selection.
Choosing Between the DD900 220V and 460V Models
The 10520GR-US (220V) and 10521GR-US (460V) are electrically interchangeable in performance: same 9.8 kW, same 364 PPD, same airflow. The selection criterion is the site's available power distribution. At 220V, the unit draws 26A — requiring a 30A or larger circuit per code. At 460V, it draws 13A — a 20A circuit is typically sufficient. Higher-voltage operation reduces conductor size and line losses over long cable runs, which is why 460V is the standard in large industrial facilities. For international or older North American sites with 208–240V 3-phase, the 220V model is the correct specification.
