MADISON, Wis. – PRESS RELEASE – In response to cultivators’ increasing dehumidification needs, Quest Dehumidifiers has launched the highest-capacity overhead unit on the market: the Quest 876.

Designed for large indoor grow rooms and greenhouses, the 876 was engineered to capture more moisture, while maintaining industry-leading energy efficiency Quest is known for, pulling 6.6 pints of water per kilowatt hour.

“The 876 builds on the success of the 506, which until now was the largest high-capacity overhead dehumidifier available,” said Clif Tomasini, business manager for Quest. “Cultivators frequently are asking for larger units as their operations increase in size and specific environmental control needs evolve.”

The 876 is the answer for any cultivator wanting to fully customize each room’s environmental controls. Using a modular approach to environmental controls, growers can manage humidity needs specific to each room depending on strain needs. Additionally, being able to hang the unit preserves valuable floor space.

Features and specs of the 876 include:

  • Integrated handles
  • Low-voltage terminal block for external controls
  • Ductable intake and dual-exhaust kits available
  • Patent-pending coil technology
  • 28.9” wide X 33.8” height X 44.7” length
  • Weight: 350 pounds

The Quest 876 is backed by a five-year warranty and has an MSRP of $11,499.95. To learn more about the 876 or any of Quest’s units, visit, or call 877-420-1330.
