Quest 746 Overview
The Quest 746 480V dehumidifier features our patented M-CoRRTM Technology. This multi-coil design reuses energy during dehumidification allowing it to be the most energy-efficient 480-volt dehumidifier on the market. This technology uses less amperage at a higher voltage, freeing up space on your electrical panel for other equipment, a game changer in controlled environments. As one of Quest’s highest capacity units, the Quest 746 480V is designed to handle high humidity loads and large spaces.
Straight from madison, WI
The Quest 746 480V dehumidifier is engineered and assembled in Madison, Wisconsin. It’s backed by a 5-year warranty for peace of mind. In addition, this unit meets California Title 24 requirements for both ducted (whole-home) and non-ducted (portable) installations.
