 The Quest 746 480V Overhead Dehumidifier is a high-capacity, energy-efficient solution designed for large spaces and high humidity loads. Featuring patented M-CoRR™ Technology, this dehumidifier uses a multi-coil design to recycle energy during dehumidification, making it the most energy-efficient 480-volt unit on the market. With its ability to operate at a higher voltage and lower amperage, the Quest 746 frees up space on your electrical panel for other equipment, making it ideal for controlled environments. Engineered and assembled in Madison, Wisconsin, the Quest 746 480V is backed by a 5-year warranty and meets California Title 24 requirements for both ducted and non-ducted installations. This dehumidifier also includes a MERV 13 filtration system to remove harmful contaminants such as dust, pollen, mold, bacteria, and some viruses from the air. It offers flexibility with both overhead and ground placement options and features an auto-restart function that restores settings after a power outage. With its low amp draw, wide operating range, and high efficiency, the Quest 746 480V provides reliable, superior humidity control for large-scale applications.
