Quest Dual 105 Overhead Dehumidifier

The Quest Dual 105 Overhead Dehumidifier extracts up to 105 pints of water, protecting your structure and indoor growing facility from mildew and mold accumulation. When you add this to your cart at GrowLight Heaven, you'll receive a free pair of Hanging Brackets as well.


  • Extremely Energy Efficient: The Quest Dual 105 is the world’s most energy efficient dehumidifier. Using only 4.9 amps, the Quest Dual 105 removes 105 ppd of water. Dehumidifier efficiency, especially for closed grows, can save substantial money in operating cost.

  • Free Hanging Brackets Included: When you add this to your cart at GrowLight Heaven, you'll receive a free pair of Hanging Brackets as well.

  • Hands-Free Monitoring of Indoor Humidity: Unlike other dehumidifiers, this overhead Quest unit has an onboard dehumidistat and operates via three humidity levels – dry, normal, and humid. Depending on the settings, the unit will kick on when the humidity rises above the preset and will turn off when the humidity is reduced 4 – 6% relative humidity.

  • Overhead or Floor Installation: Unlike traditional dehumidifiers, the Quest Dual 105 Dehumidifier can be mounted overhead, freeing up floor space for a variety of growing needs. This installation can be completed via the Quest hanging bracket with chains, allowing for more room. While overhead installation is recommended, the Quest 105 can easily be installed on the ground floor for growers whose needs may change on a day-to-day basis. Simply place the dehumidifier on the ground, ensuring there is 2.5” clearance between the bottom of the unit and the ground for sufficient gravity drainage of condensate.

  • Ideal for Mid Sized Areas: This unit is ideal for mid sized spaces where regulating humidity is really important. Before purchasing, consider the facility square footage, frequency of feeding, and water net usage for selecting the right Quest dehumidifier. To get answers to any specific questions about your facility and which unit is right for you, please reach out to us directly to have an expert contact you with all the information you need. 

  • Easy Installation- Plug & Play: In addition to overhead installation, the Quest 105 Dehumidifier is a plug and play dehumidifier, requiring no intricate installation process with circuits and wiring for ground or floor installation. The units feature an on-board low voltage terminal block that makes it easy to wire to external controls.

  • Auto Restart: This unit automatically restarts after a power outage.

  • Cool & Humid Conditions: The unit will continue to operate even when it is cool or humid outside.

  • Daisy Chain Option: Wire up to six of these models together for use in large warehouse spaces. All six will be running off the same sensor on the Quest DEH 3000 R, so all models must be in the same room. 

  • Made in the USA: The Quest Dual 105 is proudly made in the USA.

  • Long Lasting- 5 Year Warranty: These dehumidifiers are extremely strong and durable. Quest will back up your purchase with a 5-Year Warranty on the sealed system, and a 1-Year Warranty on Parts and Labor.
