Quest 335 hyper-efficient standalone overhead dehumidifier featuring patented multi-coil refrigeration system, filter life compensating smart fan, patent-pending hybrid expansion valve, onboard digital controls, and scroll compressor.
The Quest 335 Dehumidifier is engineered to meet the demanding needs of commercial cannabis growers who face the challenges of cultivations filled with moisture-producing crops. This powerful dehumidifier is designed with features such as filter compensation, M-CoRR technology, and digital controls, providing growers with an efficient and versatile solution for maintaining optimal humidity levels in their grow rooms.
One of the key features of the Quest 335 is its multi-coil design, which is similar to the one used in the highly acclaimed Quest 506. This design allows the unit to pull an impressive 350 pints of water from the air every 24 hours, even in challenging conditions with 80 °F temperature and 60% relative humidity. This outstanding performance is achieved with a low energy consumption of 9.3 KWh, making the Quest 335 one of the most energy-efficient dehumidifiers available.
The Quest 335's M-CoRR (Multi-Coil Refrigeration) technology sets it apart from other dehumidifiers on the market. This patented technology utilizes a multi-coil refrigeration design that not only provides exceptional efficiency but also recycles excess heat, reducing the overall heat output into the grow room. By minimizing the heat (BTUs) output, the Quest 335 helps maintain a comfortable environment for plants without overburdening the cooling systems.

Another notable feature of the Quest 335 is its filter compensation technology. Equipped with MERV-13 filtration, the unit can effectively trap pollen, powdery mildew, and dirt. The filter compensation technology adjusts the fan speed as the filter becomes increasingly clogged, ensuring a consistent airflow without compromising the cubic feet per minute (CFM) rate. This capability enables the Quest 335 to maintain optimal air circulation and provide a clean and healthy environment for plant growth, while maximizing energy efficiency.
