Industrial-Scale Humidity Control for the Largest Cultivation Facilities

The Quest 876 High Capacity Dehumidifier removes an extraordinary 876 pints of moisture per day at 220-240V hard-wire power, backed by patented M-CoRR Technology that recycles heat during dehumidification to achieve market-leading energy efficiency. Delivering 1,850 CFM of conditioned airflow and 58,200 BTU of thermal capacity, it handles the most demanding commercial and industrial humidity loads. Dual MERV 13 filters capture dust, pollen, mold spores, bacteria, and fine contaminants for superior air quality across massive grow spaces. Integrated handles and hang points support overhead or ground-level placement, and auto-restart after power outages keeps your environment stable around the clock.

Key Features & Benefits

• 876 Pints/Day Capacity - One of the highest-capacity commercial dehumidifiers available, engineered for facilities with extreme humidity loads and large square footage.
• M-CoRR Technology - Patented multi-coil refrigeration recycling delivers market-leading efficiency at 5,500 watts, reducing heat output into your space and lowering A/C costs.
• Dual MERV 13 Filtration - Two MERV 13 filters remove ultra-fine airborne particles including mold spores, bacteria, pollen, and dust for exceptional air quality at scale.
• 1,850 CFM Airflow - Powerful 24.7-amp draw distributes conditioned air broadly for consistent humidity reduction across large cultivation floors.
• Overhead or Ground Placement - Integrated hang points and handles allow flexible installation to suit your facility configuration and conserve floor space.
• California Title 24 Compliant - ETL listed and UL rated, meeting commercial installation requirements for ducted configurations.
• 5-Year Warranty - Engineered and assembled in Madison, Wisconsin, with Quest's industry-leading warranty for mission-critical applications.

Who Should Use This

Compatible with Quest DEH-series digital wall controllers for integrated environmental management. Dual MERV 13 replacement filters available separately. Quest hang kits available for overhead installation.

Frequently Asked Questions

Does the Quest 876 require a licensed electrician for installation?

Yes - the Quest 876 uses a hard-wire 220-240V electrical connection and must be installed by a qualified electrician. There is no standard plug-in connection for this unit.

How does M-CoRR Technology reduce operating costs at this scale?

M-CoRR recycles heat generated during dehumidification back into the refrigeration cycle, boosting moisture removal efficiency and reducing the BTUs added to your space. For a 5,500-watt unit running continuously, even small efficiency gains translate into significant electricity savings over time.

What does dual MERV 13 filtration mean for air quality?

Two MERV 13 filters provide high-level air filtration, capturing 75% or more of particles in the 0.3 to 1 micron range including mold spores, bacteria, and fine dust. This protects your crop from airborne pathogens at scale without sacrificing airflow performance.

Is overhead installation possible with the Quest 876?

Yes - the Quest 876 includes integrated hang points for overhead installation. Given the unit's substantial weight, consult a structural engineer or contractor to verify your ceiling's load capacity before mounting, and use an appropriate Quest hang kit for secure support.
