Description

Engineere & Assembled in the USAThe Quest 506 Overhead Dehumidifier is powerful and efficient for demanding commercial and industrial spaces. Its capacity makes it one of the market's most powerful and efficient commercial dehumidifiers. 

Protect valuable assets and eliminate damaging moisture in greenhouses, indoor growing facilities, warehouses, military storage spaces, and other large areas.

Note: This is available as a 208/230-volt model (Quest 506 4046300), which uses a NEMA 6-20P plug, or a 277-volt model (Quest 506 4046310) with a NEMA L7-20P plug.

Versatile Uses and Installation 

Thanks to its unique design, this American-engineered dehumidifier can be used in various industrial and commercial spaces and offers impressive MERV 13 filtration.

  • Operates in any temperature between 56 and 95 degrees F.
  • A gravity drain hose is included to remove the excess moisture it collects. You can either drain it outside or into a reservoir.
  • This overhead dehumidifier can be ducted when necessary; intake and exhaust duct kits may be purchased separately.

Note: A remote humidistat is required for use. Our customers often choose the Quest DEH3000R controller

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.

Maintain Optimal Humidity Levels

The Quest 506 Overhead dehumidifier effectively removes moisture and controls humidity, eliminating costly quality errors, preventing rust and corrosion, and maintaining the correct humidity levels for indoor growing spaces.

Overhead installation also saves floor space and helps mitigate moist air trapped near the ceiling.

Efficient Operation

The Quest 506 Overhead Dehumidifier removes an industry-leading 506 pints of moisture daily, making it one of the most efficient high-capacity designs available. 

CA Title 24 ComplianQuest's patent-pending coil technology allows for higher efficiency in a smaller unit. It pulls only 11 amps and has a maximum efficiency of 8.1 pints/kWh. This complies with California Title 24 updated regulations for energy efficiency for both overhead (portable) and ducted (whole-house) installation. No high-capacity dehumidifier can remove 500 pints of moisture in such a small frame.

Using fewer amps means the unit generates less heat--another bonus if you use this model in growing spaces.

Additional Features

  • Long Power Cord: A 10-foot power cord makes installation easy in almost any location.
  • Superior MERV 13 Filtration: Air exiting the dehumidifier is filtered with a MERV 13 filter, which catches particles like smoke, smog, bacteria, microscopic allergens, and debris. Filter changes are suggested for 6-8 weeks if the dehumidifier is used in growing spaces.
  • R-454B Refrigerant: The Quest 506 now uses R-454B Refrigerant, which is more energy efficient and has a 75 percent lower global warming potential than R-410A.  
  • 5-Year Compressor Warranty: It's backed by a 5-year compressor and refrigerant system warranty and a 1-year parts and labor warranty.  
  • Auto Restart: After power outages, this high-capacity dehumidifier returns to its previous settings once power is restored.
  • Integrated Handle: Integrated heavy-duty handles make transporting easier. The threaded rod handles can attach to a 3/8-inch rod (not included) if you use it as an overhead dehumidifier. Moving this 280-pound model will require at least two people.
  • Low Voltage Control Option: Wire the remote dehumidistat using a low-voltage terminal block.
  • Remote Humidistat Required: A remote humidistat is required for use. We recommend the Quest DEH3000R controller

Sylvane's Expert Take

This overhead commercial dehumidifier offers unmatched moisture removal of 506 pints daily, making it a top choice for large, demanding indoor environments. Its M-CORR technology ensures exceptional energy efficiency, cutting costs while maintaining ideal humidity conditions.

  • Versatile Installation: This model offers flexible installation options, including ducting capability and low-voltage control wiring, for seamless integration in any large-scale setting.
  • Advanced Air Filter: Users can upgrade their air filtration using MERV 13 filters, which improve air quality and reduce maintenance concerns.

    It gets the job done!

    We had our HVAC team set up the 506 in our large enclosed swimming pool room. It worked well right off the bat, returning water from the air to the pool. It also raised the air temperature which we expected so we'll probably save it to mostly use during cooler weather. It is not as loud as we feared which is a plus - we can't hear it through our thermal glass doors. The only problem is that it has tripped the 220 circuit breaker several times so we are reluctant to run it full time.
