Quest 205 High-Efficiency Dehumidifier

Achieve greater high-capacity moisture removal with the redesigned Quest 205 High-Efficiency Overhead Dehumidifier. This unit can remove up to 200 pints of moisture daily at 7.7 pints per kWh (AHAM conditions 80 degrees F and 60 percent RH) from large manufacturing plants, warehouses, indoor growing facilities, military storage areas, greenhouses, and indoor grow rooms.

If not properly maintained, excessive humidity can cause costly issues that result in quality errors, safety risks, and delays—all detrimental to good business operations. With ducting options and an onboard dehumidistat, the Quest 205 can help you quickly establish and maintain desirable relative humidity levels.

M-CORR Technology

This commercial dehumidifier uses Quest’s patented M-CORR technology, which increases device efficiency using multiple recovery coils to cool air and recycle energy. Quest devices with M-CORR technology use less energy than traditional dehumidifiers, pulling 30 percent more water from the air and expelling less heat.

Onboard Dehumidistat

The Quest 205’s advanced onboard dehumidistat can be set to your optimal RH and will operate when needed to maintain that set point.

When relative humidity rises above your set point, the dehumidifier automatically begins running and will continue to operate until the humidity level drops 4 to 6 percent below your preset. Once this is achieved, the unit will cycle off.

Ducting Options

Ducting is not a problem with the Quest 205. Featuring dual exhausts, the dehumidifier can be fitted to suit your individual ducting needs.

• No Ducting (Recommended): No ducting allows you to install your dehumidifier easily, set the desired preset, and enable it to perform as needed.
• Ducted Return and Supply: This setup draws warm, humid air through the inlet near the ceiling and returns dry, warm air through the exhaust outlet.
• Remote Area and Ducted Supply: This option draws hot, humid air from the same space as the dehumidifier and ducts dry, warmer air into the dehumidified space. It works well for placing the unit in another space, such as a crawl space.
• Remote Area and Ducted Return Only: This option allows the unit to draw in air from the humid room, process it, and release the dry, warm air into its space.

Plug and Play and Overhead Installation

The Quest 205 can easily be installed on the ground or floor without intricate wiring and ducting installation. If your floor space is limited, you can install it overhead, near the ceiling, using Quest Hanging Brackets and chains. This installation allows the unit to process warm, moist air more effectively near the ceiling. Simply install the unit with Quest Hanging Brackets and chains for overhead mounting.

When installing on the ground level, allow 6.75 inches of clearance between the bottom of the unit and the floor drain for gravity drainage.

Additional Features

• R-454B Refrigerant: The Quest 205 High-Efficiency now uses R-454B Refrigerant, which is more energy efficient and has a 75 percent lower global warming potential than R-410A.
• Dual Ducts: Dual ducts more efficiently draw in more moisture-laden air.
• Fan Only Runs When Dehumidifying: The fan only runs when the compressor is running and the unit is dehumidifying.
• Daisy Chain Option: Wire up to six models in large warehouse spaces. All six will be running off the same Quest DEH 3000 R sensor, so all models must be in the same room.
• MERV 13: Offers superior filtration with a standard 18 x 18 x 2-inch MERV 13 filter.
• Gravity Drain: Uses gravity to drain condensate to an outside source or an acceptable indoor drain.
• Operation Temperature: Operates in temperatures between 56 to 95 degrees F.
• Auto Restart: The unit will automatically resume operation during a power outage.
• Low Voltage Terminal: The Quest dehumidifier has a low-voltage terminal block for easier wiring to an external control.

Sylvane’s Expert Take

Experience superior humidity control with the redesigned Quest Dual 205 Overhead Dehumidifier, which surpasses many competitors by efficiently removing up to 200 pints of moisture daily. Its advanced onboard dehumidistat and unique overhead installation options provide efficient, customized moisture management that standard dehumidifiers often can't match.

• Effective Capture: The unique overhead installation captures rising moist air more effectively than floor units, optimizing humidity control in large spaces.
• Scalable Design: This model allows daisy-chaining up to six units, offering unmatched flexibility for expansive facilities needing comprehensive humidity management.
