QUEST 700 DEHUMIDIFIER

Quest 700 Dehumidifier

Ultra high-capacity dehumidifier engineered for industrial grow operations and climate-controlled facilities. The Quest 700 delivers unmatched moisture removal with industry-leading efficiency and smart control features.

The Quest 700 50hz dehumidifier features our patented M-CoRR®^TM Technology. This multi-coil design reuses energy during dehumidification allowing it to be the most energy-efficient 400-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 700 is designed to handle high humidity loads and large spaces.

The Quest 700 also features patented DART (Dynamic Airflow Response Tuning), which intelligently adjusts fan speed as defrost conditions approach. This helps slow or prevent ice buildup, allowing the compressor to keep removing water more consistently and maintain dehumidification performance across changing conditions.

The Quest 700 50hz dehumidifier is engineered and assembled in Madison, Wisconsin. It’s backed by a 3-year warranty for peace of mind.
