The Quest Dual 155 is one of the most energy-efficient commercial dehumidifiers on the market today. Removing 155 pints of water per day, this unit can save you thousands in energy costs every year compared to the competition. It gives you the flexibility to hang the unit overhead or use ductwork and keep the dehumidifier in a different space entirely.

Avoid mold and mildew that causes plant rot and structural damage in commercial areas with the Quest Dual 155 Overhead Dehumidifier. This unique low-amp dehumidifier is capable of removing up to 155 pints of water per day (AHAM) in facilities.

Commonly used in small growing spaces, warehouses, and other commercial areas, it's incredibly easy to set up with the Plug & Play feature and an onboard dehumidistat for consistent humidity monitoring and control. You can also wire up to 6 units together, use various types of ducting or non-ducting installation, and efficient design for low-cost dehumidifying.

Out-of-the-Way Installation

Install the Quest 155 in a variety of different options. Here are some solutions for installation:

• Overhead:

  Conveniently hang your Quest 155 out of the way for more growing space with the overhead installation using Quest hanging brackets. With the dehumidifier out of the way on the floor, you’re free to use the existing space for more growing capacity. Simply install the overhead dehumidifier with the additional hanging brackets for the Quest 155 and secure with chains.

• Ducting:

  Additional ducting can be added to the dual exhaust vents. Add Quest supply collars and return collars to add healthy air to different rooms.

• Ground:

  Growers may opt to install the dehumidifier on the floor of the room. This option allows growers to access the control panel and onboard dehumidistat for day-to-day use.

To further increase flexibility in where your dehumidifier can be installed, we suggest adding a Quest Universal Condensate Pump, which can be mounted directly to the unit.

Onboard Dehumidistat: Automatic Humidity Control & Monitoring

Humidity monitoring is now in your control with the onboard dehumidistat. The onboard dehumidistat allows you to preset your ideal conditions with three presets – dry (20% - 30% RH), normal (50% RH), and humid (80% - 90% RH). If the humidity rises above your preset, the dehumidistat will automatically kick on the unit, running until the humidity drops at least 4% - 6% and turning off.

To conserve energy, the Quest 155 is constructed with air-to-air heat exchange, which makes this unit an efficient option as well.

Ducting Options

As with any dehumidifier, the Quest 105 can be ducted to suit an indoor grower. For optimal performance, no ducting is recommended for the dehumidifier. However, there are other options for ducting:

• No Ducting:

  Capture humid air and release dry air without the use of ducts.

• Ducted Return & Supply:

  For optimal drying, duct humid air into the inlet and release dry, warm air into the surrounding area through the dual outlets.

• Remote Area, Ducted Supply:

  Return dry air back into your growing space by drawing warm, humid air into the unit in the same space as the dehumidifier.

• Remote Area, Ducted Return Only:

  Release dry air back into the remote or isolated area where the dehumidifier is located, and duct in humid air through the inlet.
