Quest 205 High Efficiency Overhead Dehumidifier with M-CoRR™ Technology. 200 Pints/Day. 110-120 VAC. 575 CFM. 12,800 BTU. M

What the Quest 205 Dehumidifier Pulls Out of a Room Humidity is the variable that decides whether a room finishes clean or spends its last fortnight fighting mold. The Quest 205 Dehumidifier is built for a sealed grow space rather than a damp basement. Rated removal is two hundred pints per day at eighty degrees and sixty percent relative humidity. At seventy-five degrees and fifty percent it still pulls one hundred thirty-five pints. That second figure is the one most flower rooms actually live at. Efficiency reaches 7.7 pints per kilowatt-hour at the high rating, which is where the M-CoRR heat recovery shows up on the power bill. Current draw is ten amps on a hundred-ten to hundred-twenty volt supply, so a standard twenty amp receptacle carries it. Airflow across the coil runs 575 CFM, which moves a real volume of room air rather than trickling. The filter is a MERV 13 panel measuring eighteen by eighteen by two inches. That is a meaningful step up from the MERV 11 panels fitted to the previous generation. A nine foot cord and a threaded NPT drain port finish the install list. Why an Overhead Dehumidifier Earns Its Ceiling Space Placement is where this unit parts company with a portable. Hanging it above the canopy frees floor area and drops dry air where it mixes on the way down. The cabinet measures 26.8 x 23.6 x 20.9 in and weighs 130 lb, so the mount needs real structure and two people. Total heat rejection is 12,800 BTU, of which 3,700 comes from the motor load alone. That heat has to go somewhere, and in a sealed room it becomes part of the cooling calculation. The onboard dehumidistat holds a setpoint without a separate controller, while a low voltage terminal block lets a room controller take the reins. Auto restart returns the unit to its prior settings after a power cut, which matters on an unattended weekend. Refrigerant is R454B, a lower-GWP blend now replacing R410A across the category. One limit worth planning around is the minimum operating temperature of fifty-six degrees. Below that the coil frosts and this is the wrong tool for the job. Key Features M-CoRR Heat Recovery: Energy recycled inside the refrigeration loop lifts capacity without lifting the amp draw. 200 Pints Per Day: Rated at eighty degrees and sixty percent RH, with 135 pints at the more common seventy-five and fifty. Ten Amp Draw: A single standard twenty amp circuit carries the unit and still leaves headroom for other equipment. MERV 13 Filtration: The eighteen inch panel traps finer particulate than the MERV 11 filters used on older units. Overhead or Floor Mount: The same cabinet hangs from structure above the canopy or sits in a corner on the floor. Onboard Dehumidistat: Setpoint control lives on the unit, with a low voltage terminal block for an external controller. Auto Restart: Prior settings return by themselves once power comes back after an interruption. R454B Refrigerant: A lower-GWP blend replaces R410A and keeps the unit current with refrigerant regulation.
