Quest 746 480V High-Capacity Dehumidifier – 746 Pints/Day

Get to Know the Quest 746 480V High-Efficiency Dehumidifier with M-CoRR Technology – 746 Pints/Day

The Quest 746 480V Grow Dehumidifier is built to handle high humidity loads in large-scale grow environments, offering industry-leading energy efficiency thanks to patented M-CoRR™ Technology.

This high-capacity dehumidifier removes an enormous volume of moisture while operating at higher voltage and lower amperage, meaning it frees up space on your electrical panel for other critical equipment. That’s a game-changer for industrial-scale grow rooms, greenhouses, and cultivation facilities that demand maximum efficiency without overloading power systems.

Built for ducted and non-ducted setups, and California Title 24 compliant, the Quest 746 is designed for reliability, precision, and long-term energy savings—exactly what top-tier growers need to maximize yield and optimize their environment.
