Overview
The Quest 335 208/230V dehumidifier is engineered specifically for commercial and industrial applications facing heavy moisture loads, such as cultivations filled with moisture-producing crops and water treatment plants. At the core of Quest’s 335 features are filter compensation, M-CoRR Technology, and digital controls with the versatility to work with external controls.
The Quest 335 uses a multi-coil design similar to the one used in the Quest 506. The end result is 350 pints of water pulled from the air every 24 hours at 80F and 60% relative humidity at 9.3 KWh.
When you combine the dollars associated with energy consumption, reduced air conditioning usage, and the consistent environment the filter compensation feature provides, the 335 is one of the most cost-effective units on the market.
M-CoRR Technology
Both Quest 335 units (208/230V and 277V) boast our unique patented M-CoRR technology. This multi-coil refrigeration design recycles excess heat to provide the highest efficiencies available on the market, while reducing heat (BTUs) output into your space.
In addition to industry-leading MERV-13 filtration, the 335 features Quest’s filter compensation technology. Filter compensation technology which increases fan speed as the filter becomes increasingly clogged with pollen, powdery mildew and dirt. This speed adjustment 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 is able to work consistently and constantly to optimize your grow room environment with maximum energy efficiency and consistency.
The Quest 335 dehumidifier is engineered and assembled in Madison, Wisconsin. It’s backed by a 5-year warranty. In addition, this unit meets California Title 24 requirements for both ducted (whole-home) and non-ducted (portable) installations.
