Quest 706 Overhead Dehumidifier Quest dehumidifiers are among the most energy-efficient and durable machines on the market, designed specifically for indoor plant cultivation in controlled indoor environments. Conceived and assembled in America, these quiet yet powerful and energy-saving dehumidifiers feature quiet operation while remaining exceptionally energy efficient. Dehumidifiers with growing room-specific water removal ratings have no equal. When reading water removal rates on other dehumidifiers, keep this fact in mind; in general these devices will be rated at 32 degrees with an 80% relative humidity reading; however a machine which claims 50 litres in these conditions would likely only pull approximately 60% of this figure in real grow room conditions. Assuming there is no extraction in place, every drop of water consumed by plants will evaporate back into the room via transpiration through their leaves and back into the room; thus if your garden consumes 50 litres daily it would require dehumidifying 50 litres daily to control humidity throughout all stages of growth. It may be difficult to gauge exactly how much your garden will drink until the full flower has set in; we have discovered that for every 1000W of light, you have, about 10 L of dehumidification should provide total control of relative humidity throughout all stages of growth. The Quest 706 is the highest capacity dehumidifier available designed specifically to maximize energy efficiency and grower needs. Equipped with proprietary coil technology not available elsewhere, the Quest 706 works around the clock to optimize your grow environment with maximum energy efficiency and flexibility. 706 pints per day at 26.7F, 60% RH (706 Pints 335 Litres) Nominal 230V, 18.6Amps @ 26.7C/60%RH, 4150 Watts Efficiency of 3.4 Litres/kWh Must be direct-wired Ductable intake and dual exhaust kits are available 3-year warranty Integrated handles Patented coil technology unlike anything else on the market Low voltage terminal block for external controls Requires a buck/boost transformer to run on 208V/277V Height: 33.8” (73.4CM) Width: 28.9” (85.9CM) Length: 44.7” (113.5CM) Weight: 350 LBS (159 KGS)
