Commonly used in small growing spaces, warehouses, and other commercial areas, it's incredibly easy to set up. With Plug & Play design and an onboard dehumidistat, this dehumidifier provides effective humidity control for retail spaces, convenience stores, restaurants, multi-family homes, theaters, and schools, as well as indoor grow houses.

Out-of-the-Way Installation

Install the Quest 155 using one of these installation options for best use in your space:

  • Overhead: Free up more growing space by conveniently hanging your Quest 155 out of the way using overhead installation. Utilize the additional hanging brackets for the Quest 155 and secure with chains.
  • Ducting: Additional ducting can be added to the dual exhaust vents. Add the supply and/or return duct kit 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.

Control Multiple Units Easily

If you're installing the units overhead or daisy-chaining multiple units--you can daisy chain up to 6 units together, you need a remote controller. The Quest DEH 3000R is popular because it comes with a remote sensor. This Honeywell wall-mounted humidistat is also a common choice.

Onboard Dehumidistat: Automatic Humidity Control & Monitoring

Consistent relative humidity is now in your control with the onboard dehumidistat. Preset your ideal conditions using one of three settings – dry (20% - 30% RH), normal (50% RH), and humid (80% - 90% RH). When the RH 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 very efficient.

Ducting Options

Duct the overhead dehumidifier in one of three ways to suit your growing and dehumidification needs.

  • No Ducting: Capture humid air and release dry air without the use of ducts.
  • Ducted Return and 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.

Additional Features

  • Temperature Operation: The Quest 155 can operate in temperatures between 56 – 95 degrees Fahrenheit.
  • Air-to-Air Heat Exchanger: Cooled, dehumidified air pre-cools incoming air, reducing energy output.
  • Fan Only Runs Whens Dehumidifying: The fan only runs when the compressor is running and the unit is dehumidifying.  
  • Auto Restart: The unit can automatically restart after a power outage.
  • R410A Refrigerant: The Quest dehumidifier uses environmentally friendly R410A refrigerant.
  • Easy Wiring: This dehumidifier features a low voltage terminal block for easier wiring to an external control.

Note  The Quest Dual 105 Overhead Dehumidifier uses aNEMA5-15Pplug type. This is a 115-volt/8-amp, 3-prong plug with a face that looks like this: NEMA 5-15P Plug Face
