Ebac DD1200 Desiccant Dehumidifier – Model 10541GR-US (460V, 3-Phase)
The Ebac DD1200 (10541GR-US) is the highest-capacity unit in Ebac's DD desiccant series at 562 PPD, running on 460V 3-phase at 15A and 11.8 kW. It moves 705 CFM of process air and 195 CFM of regeneration air through 5" and 4" duct connections, operates from -4°F to 104°F, and weighs 200 lbs in a stainless steel housing 28" × 23" × 56". The PPS rotor with 82% active silica gel, washable design, and integrated ammeter/hour meter place it as the specification for high-moisture industrial environments requiring sub-zero capability.

Where the Ebac DD1200 Performs
Large-scale cold storage facilities requiring a single desiccant unit to handle the full moisture load of a 30,000+ sq ft frozen or refrigerated space specify the DD1200 rather than deploying multiple smaller units. Pharmaceutical manufacturing plants building validated low-humidity cleanrooms use it because the 562 PPD and 705 CFM output can maintain very low dewpoints in large process areas. Military and aviation depot maintenance facilities, where archival humidity control for sensitive electronics and equipment must operate year-round through winter temperatures, require the -4°F floor that eliminates refrigerant alternatives. At 200 lbs, the DD1200 weighs only slightly more than the DD900 (198 lbs) despite extracting 54% more moisture.
DD1200 at the Top of Ebac's Desiccant Lineup
The DD1200 (562 PPD, 705 CFM, 15A/460V) is the capacity leader in the DD series, stepping up from the DD900 (364 PPD, 530 CFM, 13A) and the DD700 (231 PPD, 410 CFM, 10A). All three share -4°F minimum operation, 5"/4" duct sizing, stainless construction, and the same rotor technology. The DD1200's 56" height is 8" taller than the DD900, which may require clearance consideration in installations with low ceilings. Process airflow of 705 CFM is adequate for large-zone desiccant drying when the target dewpoint is below what refrigerant units can achieve.

What is the extraction rate of the Ebac DD1200 10541GR-US?
The DD1200 10541GR-US extracts 562 PPD — the highest capacity in Ebac's DD desiccant series, 54% more than the DD900 (364 PPD) and 143% more than the DD700 (231 PPD).
What are the electrical requirements for the DD1200 10541GR-US?
The 10541GR-US requires 460V, 3-phase, 60 Hz at 15A (11.8 kW). Circuit protection should be sized at 20A or larger per electrical code.
What is the minimum operating temperature of the Ebac DD1200?
The DD1200 operates down to -4°F — the same as the DD700 and DD900. Desiccant adsorption is thermally driven and maintains performance at sub-zero temperatures where refrigerant dehumidifiers fail entirely.
How does the DD1200 compare to the DD900 and DD700?
All three share -4°F operation, stainless steel construction, 5"/4" duct sizing. DD1200: 562 PPD, 705 CFM, 15A/460V, 56" H. DD900: 364 PPD, 530 CFM, 13A/460V, 48" H. DD700: 231 PPD, 410 CFM, 10A/460V, 40" H. The DD1200 also has the highest power draw at 11.8 kW.
What process airflow and duct sizes does the DD1200 10541GR-US use?
Process air: 705 CFM through a 5" duct connection. Regeneration air: 195 CFM through a 4" duct. These are the same duct sizes as the DD700 and DD900, allowing consistent installation planning across Ebac's DD series.
How tall is the DD1200 and does ceiling height matter?
The DD1200 stands 56" (4'8") tall — 8" taller than the DD900's 48" and 16" taller than the DD700's 40". This additional height requires adequate ceiling clearance above the unit, particularly in low-ceiling mechanical rooms or mezzanine installations.

Located in the Twin Cities in Minnesota, we acquired our Brio Air Filter in mid-late Spring of this year (2023) when pollen count was high and we were beginning to experience the effects of Poor Air Quality Index as a result of smoke particulates from fires in Canada that caused the air in much of Minnesota to become hazy and simply dirty.
It is so easy to share our experience with the Brio Air Filter given how quickly and efficiently it removed pollen, dust, and smoke particles from the environment inside our home. Two people in our home who suffer from pollen-related allergies during the spring immediately experienced easier breathing and elimination of symptoms within the house. With respect to smoke particulates from Canada drifting into our environment, EVERYONE in our home experienced directly improved breathing and smell of the air when entering from outside.
An additional piece of information to account for is that we have always employed high grade furnace filters in our home’s central HVAC system. With that high grade filtration in place both prior to and after acquiring a Brio home air filter, we all quickly agreed that deploying the Brio in our home made an easily noticeable positive difference in breathing inside our home. Additionally, those of us who clean our home have observed that dust builds up slower on our floors and furniture than before we deployed the Brio unit.
We did note that the Brio is not as quiet as a few other brands/models on the market that we have tried in our home but the efficiency and quality of the filtration, along with the air turnover rate it provides,allows us to locate the Brio unit in central rooms away from the bedrooms. Since we made that change there has been no noise-related effect on our sleep, while the unit maintains the same level of air cleanliness throughout our home.
A last key point to make is how easy the Brio unit is to maintain. The simplicity of the modular construction of the Brio unit makes it very quick and easy to keep the filtration sections clean. We have not yet reached a point of filter replacement but it is obvious to us that the replacement will take a matter of seconds and can be executed by anyone in our home, including our 10-year-old son.
It seems to help reduce my allergy issues. We're glad we bought it. The only problem I had was not seeing any cubic footage recommendations in the online description when purchasing the unit. Bedrooms vary widely in size!!
