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.

  • Weight: 198 lbs

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.

Frequently Asked Questions

What is the difference between the Ebac DD900 10520GR-US and 10521GR-US?
Both are the same DD900 desiccant dehumidifier with identical 9.8 kW output and 364 PPD extraction. The 10520GR-US runs on 220V 3-phase at 26A; the 10521GR-US runs on 460V 3-phase at 13A. Select based on the available power distribution at your site.
What is the current draw of the DD900 10520GR-US at 220V?
The 10520GR-US draws 26A at 220V 3-phase, compared to 13A for the 460V model. At 220V, circuit protection and wiring should be sized for 30A or larger per electrical code.
What is the extraction rate of the Ebac DD900 10520GR-US?
The 10520GR-US extracts 364 PPD under typical desiccant operating conditions — identical to the 460V model. Desiccant extraction performance is maintained at low temperatures, unlike refrigerant dehumidifiers.
What is the minimum operating temperature of the DD900 220V model?
The 10520GR-US operates down to -4°F — the same as the 460V model. The silica gel rotor adsorbs moisture thermally, maintaining performance at sub-zero temperatures where refrigerant dehumidifiers fail entirely.
What duct sizes does the DD900 10520GR-US require?
Process air requires a 5" duct connection at 530 CFM; regeneration air requires a 4" duct at 147 CFM. Duct sizing applies equally to both the 220V and 460V variants.
Why specify the 220V 3-phase DD900 instead of the 460V model?
Specify the 10520GR-US for facilities with 208–240V 3-phase distribution, including international sites and older North American buildings. The 460V model is the better choice for large industrial facilities with standard 460V 3-phase distribution, as it draws half the current (13A vs. 26A) over the same power output.
