Quest 876 High-Efficiency Overhead Dehumidifier
Designed specifically for large industrial spaces and commercial greenhouses, the Quest 876 High-Efficiency Overhead Dehumidifier is the highest-capacity commercial dehumidifier available. Quest 876 offers long-term, continuous moisture removal for a wide range of industrial applications including large warehouses, military storage facilities, factories, and much more.
Take advantage of trusted quality, unbeatable efficiency, and powerful moisture removal in tough environments. Removing up to 876 PPD at AHAM, you’ll need fewer units in large areas.
Top Quest High Efficiency Dehumidifier Benefits
- The most powerful dehumidifier available: Quest 876 High-Efficiency Overhead Dehumidifier removes 876 pints of moisture at AHAM conditions, meaning less units used in large commercial grow areas or industrial spaces.
- Trusted American-engineered quality with 5-year warranty.
- One of the most efficient dehumidifiers on the market, removing 6.6 pints per kWh.
- Patented coil technology pre-cools and post-heats the air so the unit doesn’t have to work as hard to remove moisture from the air. This design simplifies the process and maximizes efficiency and longevity.
Note: This is a direct (hard) wired dehumidifier and can’t be used with a power cord. An external controller, like the Quest DEH3000R Controller, is required for operation.
Additional Features
- Operating Temperature Range: Use this powerful dehumidifier in tough environmental conditions between 56 and 110 degrees F.
- Easy to Hang: Top lift points make it easier to hang from the ceiling than previous dehumidifier options. Save floor space by suspending this unit from the ceiling.
- Simple to Move: Measuring less than 3 feet wide, Quest designed this powerful dehumidifier to fit easily between doors.
- External Wiring & Daisy Chain Option: Its low voltage control works in any building automation with a 24V system. This wiring schema also allows for daisy chaining multiple units together.
- Conserve Space and Power: Use fewer dehumidifiers to keep your industrial or commercial space at the ideal humidity level.
- Fan Operation Options: There are two fan operating options: Set the fan to run continuously, or to run only when dehumidifying.
QUEST’S PATENTED TECHNOLOGY | M-CoRR™
Providing the most energy-efficient dehumidification
The secret behind Quest’s unparalleled energy-efficiency is their patented multi-coil design, M-CoRR (short for Multi-Coil Refrigeration Recovery). You won’t find this technology anywhere else.
Engineered for maximum performance, Quest’s M-CoRR is the most energy-efficient and the best return on your investment, paying for itself in energy savings over time. M-CoRR’s innovative design performs better over a wider range of dew points, even at colder temperatures, and maintains capacity regardless of airflow fluctuations.
How Does Quest’s M-CoRR Technology Work?
Traditional refrigerant dehumidifiers have a single refrigerant-filled evaporator coil that cools the air passing through it to extract the water from the air. Once air cools below the dew point, water condenses. Energy captured in the refrigerant during water removal returns to the air in the form of heat at the second coil, the condenser.
The magic of Quest’s M-CoRR Technology is its multiple coils. Quest designed the typical evaporator coil into three separate refrigerant-filled coils: the pre-evaporator, evaporator, and recovery coil.
The first coil, the pre-evaporator, cools the air. The second coil, the evaporator, cools it even further to pull out the water. The third coil recovers the energy from pre-cooling the air and recycles it back into the evaporator for reuse.
What Are The Benefits Of Using M-CoRR?
Highest Efficiency. Lowest Energy Usage
Higher efficiency = lower electricity usage per pint of water removed. M-CoRR technology pulls more water out of the air per kilowatt hour than any other dehumidification technology. Period.
Less Heat Output
Inefficiency = Heat. It takes energy to run the fan and compressor in your dehumidifier. During dehumidification, this energy converts to heat that warms your room. The more energy your dehumidifier consumes, the more heat it expels. Quest dehumidifiers featuring M-CoRR technology are the most efficient dehumidifiers in the world, which means they put less heat in your environment.
More Capacity, Smaller Footprint
Your space is valuable. Dehumidifiers powered by M-CoRR are more compact. This technology averages over 20% smaller than traditional LGR dehumidification technology of the same capacity.
Wide Operating Rage. Tighter Control
Thanks to its multiple coils, M-CoRR technology equips Quest to maintain performance better than traditional dehumidification equipment, even in cooler temperatures and dew points, with less frequent and faster defrost cycles. Less time spent in defrost neutralizes spikes in temperature and relative humidity, keeping the environment consistent and, in indoor cultivations, VPD dialed in.
