The Quest 335 208/230V & 277V dehumidifier is engineered specifically for commercial spaces facing a heavy moisture load, like indoor agriculture and water treatment facilities. At the core of Quest’s 335 features are our sophisticated refrigeration system, M-CoRR Technology, and digital controls with the versatility to work with external controls.

In addition to industry-leading MERV-13 filtration, the 335 features Quest’s filter compensation technology, which increases fan speed as the filter becomes increasingly clogged with pollen, powdery mildew, dust, and dirt. This speed adjustment with static pressure changes allows for the same amount of air to pass through the filter without reducing the cubic feet for minute (CFM). As a result, the Quest 335 can work consistently and constantly to optimize your environment with maximum energy efficiency and consistency.

Patented M-CoRR Technology

Both Quest 335 units (208/230V and 277V) boast our unique patented M-CoRR Technology. This advanced multi-coil design is similar to the one used in the Quest 506. The end result is 345 pints of water pulled from the air every 24 hours at 80F and 60% relative humidity at an impressive 8 pints/kWh.

All refrigerant dehumidifiers create heat as a byproduct of the dehumidification process. Our multi-coil refrigeration design recycles excess heat to provide the highest efficiencies available on the market, while reducing heat (BTUs) output into your space. When you combine the dollars associated with low energy consumption, reduced air conditioning usage, and a consistent environment to prevent product loss and support product quality, the Quest 335 is one of the most cost-effective units on the market.

The Quest 335 dehumidifier is engineered and assembled in Madison, Wisconsin. It’s backed by a 5-year warranty for after-purchase peace of mind. In addition, this unit meets California Title 24 requirements for both ducted (whole-home) and non-ducted (portable) installations.
