Quest 155 High-Efficiency Dehumidifier
Description
Description
Avoid mold and mildew that cause plant rot and structural damage in commercial and industrial spaces with the Quest 155 Overhead Dehumidifier (4046120). This low-amp dehumidifier can remove up to 155 pints of water per day (AHAM) in various spaces.
Commonly used in small growing spaces, warehouses, and other commercial areas, it's incredibly easy to set up. With a plug-and-play design and an onboard humidistat, this dehumidifier provides effective humidity control for retail spaces, convenience stores, restaurants, multi-family homes, theaters, schools, and 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 an overhead installation. Utilize the additional hanging brackets for the Quest 155 and secure them with chains.
- Ducting: Additional ducting can be added to the dual exhaust vents. Add the supply and/or return duct kits to add healthy air to different rooms.
- Ground: Growers may opt to install the dehumidifier on the room's floor. This option allows growers to access the control panel and onboard humidistat for day-to-day use.
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.
CA Title 24 Compliant
With an energy factor of 8.5 p/kWh (pints per kilowatt-hour), the Quest 155 is highly efficient and compliant with California Title 24 energy efficiency regulations for overhead (portable) and ducted (whole-house) installations.
Control Multiple Units Easily
You will need a remote controller if you're installing the units overhead or daisy-chaining up to 6 units together. The Quest DEH 3000R is popular because it comes with a remote sensor.
Onboard Humidistat: Automatic Control and Monitoring
Consistent relative humidity is under your control with the onboard humidistat. Preset your ideal conditions using one of three settings: dry (20 to 30 percent RH), normal (50 percent RH), or humid (80 to 90 percent RH). When the RH rises above your preset, the unit will automatically turn on, running until the humidity drops at least 4 to 6 percent and then turning off.
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 ducting.
- 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 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 between 56 and 95 degrees F.
- Air-to-Air Heat Exchanger: Cooled, dehumidified air pre-cools incoming air, reducing energy output for more efficient operation.
- Fan Only Runs When 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.
- R454B Refrigerant: The Quest 155 dehumidifier uses cutting-edge R454B refrigerant, which is more efficient and environmentally friendly.
- Easy Wiring: This dehumidifier features a low-voltage terminal block for easier wiring to an external control.
Note: The Quest 155 Overhead Dehumidifier uses a NEMA 5-15P plug type. This is a 115-volt/8-amp, 3-prong plug with a face that looks like this: 
Sylvane's Expert Take
The Quest 155 Overhead Dehumidifier efficiently removes up to 155 pints of moisture daily, preventing mold and mildew damage while maintaining healthy humidity levels. Its versatile overhead and ducted installation options free up valuable floor space and ensure seamless integration into various commercial environments.
- Asset Protection: Controlling humidity with the Quest 155's advanced technology protects valuable inventory and equipment by preventing moisture-related damage, potentially reducing long-term operating costs.
- Ad-Ons Available: Consider an optional remote controller for overhead installations or daisy-chained units to streamline monitoring and adjustments.

So far, this has been a good product but if you use the offered ceiling mounting supports the filter doors are blocked by the supports and you will need to lower it to replace the filter. bad design.
