Quest 746 - 480v

The Quest 746 480V High-Efficiency Dehumidifier is the next generation of commercial and industrial dehumidification featuring Quest’s 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. Engineered for large-scale environments, this high-capacity unit combines superior moisture removal, energy efficiency, and smart digital controls—all in a more compact design.

The Quest 746 480V uses less amperage at a higher voltage, freeing up space on your electrical panel for other equipment, a game-changer in controlled environments. With its reduced height, it fits where other industrial dehumidifiers can’t, making it ideal for mechanical rooms, overhead installations, and space-limited facilities. Built for performance, it removes approximately 730 pints of moisture per day (80°F, 60% RH) with an industry-leading efficiency of 8.3 pints per kWh, helping facility managers lower operating costs without compromising climate control.
