Quest HGC700943 Dehumidifiers

HIGHER YIELDS, FEWER PROBLEMS

The right dehumidification setup can take your indoor grow operation to the next level. Say goodbye to crop losses from molds and other pests, and say hello to peak productivity with the Quest Dehumidifier.

Quest has the most energy-efficient dehumidifiers available, using the least electricity and removing more pints of water per kWh at the widest temperature range. Quest’s innovative design also creates the lightest heat load on your HVAC, paying for itself in energy savings.

Higher Crop Yields, Less Problems

One of the biggest challenges for the indoor farming industry is creating and maintaining a stable, consistent environment for plants to flourish. Without a reliable climate, you could lose your entire crop. Once you lose control of your environment, serious crop-crushing issues begin to take hold. The two main “crop-crushers” are concerns many growers face at one time or another: powdery mildew and botrytis, more commonly known as bud rot. Either of these issues can destroy a grow and lead to lost revenue.

Proper Dehumidification Can Make All The Difference

Whether it’s a greenhouse or a hydroponic grow the same principles come into play when you’re fine-tuning a setup. For moisture control and dehumidification, the three most important aspects are proper sizing, placement, and airflow. Quest engineers developed our product offerings to allow for flexible and customizable options to address all three.

QUEST'S PATENTED TECHNOLOGY | M-CoRR™

Providing the most energy-efficeint dehumidification

The secret behind Quest’s unparalleled energy-efficiency is our patented multi-coil design, or as we like to call it: M-CoRR (short for Multi-Coil Refrigeration Recovery). You won’t find this technology anywhere else.

M-CoRR is engineered for maximum performance, allowing Quest to be 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 (because cold air holds less water). Once the air is cooled below the dew point, water condenses. Energy captured in the refrigerant during water removal is returned 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 to be recycled 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.

Which Quest Dehumidifiers feature M-CoRR?

The Quest Dehumidifiers are broken apart by the High-Efficiency Series and the Standard Overhead Series. All Quest Dehumidifiser in the High-Efficiency Series feature the M-CoRR Technology. The Overhead Series are Quest's standard units that do not feature M-CoRR. Please note: Models in the high-efficiency series can still be installed overhead if that models allows.
