Quest 876 High-Capacity Dehumidifier

Designed specifically for large industrial spaces and commercial greenhouses, the Quest 876 is the highest-capacity commercial dehumidifier available. It offers long-term, continuous moisture removal for a wide range of industrial applications including large warehouses, military storage facilities, factories, and much more.

Take advantage of trusted quality, unbeatable efficiency, and powerful moisture removal in tough environments. Removing up to 876 PPD at AHAM, you'll need fewer units in large areas.

Top Quest High Efficiency Dehumidifier Benefits

• The most powerful dehumidifier available: It removes 876 pints of moisture at AHAM conditions, meaning less units used in large commercial grow areas or industrial spaces.
• Trusted American-engineered quality with 5-year warranty.
• One of the most efficient dehumidifiers on the market, removing 6.6 pints per kWh.
• Patented coil technology pre-cools and post-heats the air so the unit doesn't have to work as hard to remove moisture from the air. This design simplifies the process and maximizes efficiency and longevity.

Note: This is a direct (hard) wired dehumidifier and can’t be used with a power cord. An external controller, like the Quest DEH3000R Controller, is required for operation.

Additional Features

• Operating Temperature Range: Use this powerful dehumidifier in tough environmental conditions between 56 and 110 degrees F.
• Easy to Hang: Top lift points make it easier to hang from the ceiling than previous dehumidifier options. Save floor space by suspending this unit from the ceiling.
• Simple to Move: Measuring less than 3 feet wide, Quest designed this powerful dehumidifier to fit easily between doors.
• External Wiring & Daisy Chain Option: Its low voltage control works in any building automation with a 24V system. This wiring schema also allows for daisy chaining multiple units together.
• Conserve Space and Power: Use fewer dehumidifiers to keep your industrial or commercial space at the ideal humidity level.
• Fan Operation Options: There are two fan operating options: Set the fan to run continuously, or to run only when dehumidifying.
