Active Air Dehumidifier 190 Pint | 1,290 sq ft, Digital Control

What the Active Air Dehumidifier Pulls in 24 Hours

Rated removal is 190 pints per 24 hours at 86 °F and 80% relative humidity. At the cooler, drier 80 °F and 60% condition the figure is 120 pints. That is the number worth sizing against in a room already held on target. Coverage runs up to 1,290 sq ft on a ten-foot ceiling, or 12,900 cu ft of air. Operating range is 41 °F to 95 °F. Power is 1,350 W at 115 V, drawing 11.3 A. Refrigerant is R410A with a 27.5 oz charge. The cabinet measures 21.5 x 22 x 39 in and weighs 121 lb, standing on casters. A heavy-duty compressor sits behind a powder-coated metal casing rather than a plastic shell. The evaporator has been redesigned for better performance, and a built-in defrost cycle engages at 32 °F. A removable filter pulls out for cleaning, and a 10 ft drain hose ships with the unit. Automatic restart brings the settings back after a power cut, which is what lets it sit downstream of an external humidity controller. Part number is AADHC1802P, UPC 638104022651, with ETL registration 5006106.

Sizing a 190 Pint Dehumidifier to a Flower Room

A 190 pint dehumidifier gets sized by the water the plants give back rather than by floor area alone. Whatever goes into the tank leaves again through the canopy, so irrigation volume is the real driver. That is why the pint figure at target conditions tells the truth and the headline figure flatters. Any unit rated high at warm and wet conditions reads lower once the room is actually under control. Lights-off is the window that catches people out. Air temperature falls, relative humidity climbs toward dew point, and moisture lands on the coolest surfaces in the room. Running the unit through the dark period is usually what keeps botrytis out of a dense canopy. Position it so the discharge sweeps across the canopy rather than into a corner. The casters make that easy to adjust once the room is running and the dead spots show themselves. Plumb the drain to a floor drain or a sump rather than to a bucket somebody has to remember. Give it a circuit of its own, because a compressor this size on a shared breaker will trip on starting current. Pull the filter monthly in any room carrying perlite or coir dust, since a loaded filter costs capacity before it costs anything else.

Key Features

• 190 pints at 86 °F, 80% RH: And 120 pints at the cooler 80 °F, 60% condition.
• 1,290 sq ft coverage: Up to 12,900 cu ft of air on a ten-foot ceiling.
• 1,350 W on 115 V: Draws 11.3 A, so it wants a circuit of its own.
• Defrost from 32 °F: A built-in cycle keeps the coil clear at the low end of the range.
• Automatic restart: Settings return after an outage and it follows an external controller.
• Powder-coated metal casing: A heavy-duty shell and compressor rather than a plastic housing.
• Casters and a 10 ft hose: Reposition it in a running room and plumb the drain away.
