QUEST'S PATENTED TECHNOLOGY | M-CoRR™

Quest sets the industry standard by providing the most energy-efficient dehumidification solutions, a feat achieved through our exclusive patented multi-coil design, known as M-CoRR (Multi-Coil Refrigeration Recovery). This groundbreaking technology is unique to Quest, setting our dehumidifiers apart from the competition.

M-CoRR is meticulously engineered for maximum performance, positioning Quest as the pinnacle of energy efficiency and offering the best return on investment.

The technology's innovative design excels across a broad spectrum of dew points, even in colder temperatures, and maintains optimal capacity regardless of fluctuations in airflow. This ensures that Quest dehumidifiers not only stand out for their unparalleled efficiency but also prove to be a wise investment, paying for themselves through significant energy savings over time.

How Does Quest's M-CoRR Technology Work?

Quest's M-CoRR Technology revolutionizes dehumidification by utilizing three separate coils - pre-evaporator, evaporator, and recovery coil. This innovative approach enhances efficiency by kickstarting the cooling process, extracting water efficiently, and recycling energy. Quest's commitment to pushing technology boundaries ensures superior moisture control and energy utilization in dehumidification systems.

Highlighted features of 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.

FAQ Section

How do I size a dehumidifier for a grow room?
Plants transpire about 97% of the water they receive, so the amount of water your plants consume is approximately the amount that needs to be removed each day. For example, 30 plants each receiving ½ gallon per day is an average of 15 gallons water per day. Every gallon of water is 8 pints. This example works out to 120 pints per day.
Isn’t my air conditioner a dehumidifier?
Yes, but there are issues with this solution.
1. Air conditioners remove water only when they are running. In most cases when the grow lights are off, the air conditioner is off as well. Lights-off time is when humidity is most problematic.
2. Using an air conditioner to dry a room will overcool the room, potentially causing plant stress. This will also use a significantly greater amount of energy than a Quest commercial dehumidifier.
3. The more energy efficient the air conditioner, the less moisture it actually removes. An efficient air conditioner is a terrible dehumidifier.
4. The re-heat method. Some air conditioners offer an optional heating coil as a dehumidification option. Essentially, by adding artificial heat to the room, the air conditioner is forced to operate when the lights are off and thus the air conditioner removes water. While this method works, and can be used in a pinch, it’s a poor long term solution and will use 4-8x the energy as a Quest dehumidifier. 4-8x the energy use is roughly equal to $5,000-$25,000 per year in unnecessary energy consumption.
What is the ideal humidity?
Because every plant is different, it is hard to pick just one number. However, most research indicates that 45-55% RH is the safe zone where plants are healthy, spore germination is unlikely, and pests find the environment unappealing.
How much money does a Quest dehumidifier save me in electricity?
Quest is the leader in energy efficiency and one of our models is the most energy efficient dehumidifier ever built. Depending on the model, Quest dehumidifiers can save commercial growers $100-$200 a month in electricity per unit. That’s $1,200-$2,500 per dehumidifier per year.
Can the water be reused?
Yes, Quest dehumidifiers produce neutral pH, very low TDS water. This water is safe for all plants, even consumable ones.
