Quest 200 Overhead Dehumidifier (50Hz) | 90L/Day | 3.9 L/kWh Efficient | 500 CFM | MERV 13 Filter | 230V | Commercial Grow & Dry Rooms

The Quest 200 Overhead Dehumidifier (50Hz) is built for growers and facility operators who need high-capacity moisture removal without sacrificing efficiency or space. Designed specifically for 50Hz regions, it’s an ideal solution for moderate-sized grow rooms, dry rooms, storage areas, and climate-controlled facilities where stable humidity is essential.

Powered by Quest’s proprietary M-CoRR Technology, the Quest 200 delivers excellent energy performance, achieving up to 3.9 L/kWh (at 26.7°C / 60% RH). Its efficient operation and reduced heat output can help lower running costs while improving environmental stability.

Installation is also streamlined: this next-generation design eliminates the need for a separate hang kit. Simply use the built-in lift and hang points and insert threaded rod for a clean overhead install.

Onboard digital controls allow fine-tuned RH setpoints, and provide preventative maintenance notifications, diagnostic feedback, and a dark mode setting for low-light environments. Engineered and assembled in the USA, the Quest 200 is a reliable, high-performance dehumidification solution for serious humidity control.
