Quest 335 Industrial Dehumidifier — 350 Pints/Day - 277V
The Quest 335 277V dehumidifier offer the same quality and features as the original Quest 335 208/230V units, but instead offer 277V voltages for use in industrial facilities. The 277V unit is a great fit for grow rooms, many of which traditionally have 277V outlets already installed for lighting. Additionally, these higher voltage units use less amperage, freeing up electricity for other equipment in the grow room.
Built with patented M-CoRR technology, this unit is your route to achieving an optimum moisture level, crucial for operations in agriculture, industrial manufacturing, and other moisture-sensitive industries. With its 335-pint-a-day capacity, you can easily maintain the right amount of humidity around the clock.
But even with the Quest 335 running round-the-clock, it still manages to pull more water for every kilowatt-hour, giving you more savings. And with the MERV 13 filtration system, contaminants stay away from your controlled environment.
This high-capacity dehumidifier is also easy to install and use and use. With integrated handles and hang points, the Quest 335 can be suspended overhead to free up valuable floor space or placed on the floor for no-frills operations. The industry’s lowest amp draw ensures less heat output, preserving a comfortable ambiance.
The Quest 335 meets California Title 24 requirements, is UL-certified and ETL-listed, and has a five-year warranty.
