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.
