Dial in your flower. Protect your dry.
Purpose-built for commercial spaces with heavy moisture, the Quest 746 480V delivers powerful, energy-efficient humidity control for both flower rooms and dry rooms. With patented M-CoRR technology, it removes up to 730 pints/day at an industry-leading 8.3 pints/kWh—helping growers hit precise humidity targets at a wider dewpoint operating range than competitors, while lowering operating costs.
In flower rooms, maintain tight VPD control to maximize yield, terpene retention, and consistency. In dry rooms, prevent mold, preserve quality, and fine-tune drying curves for a superior final product.
Running on 480V, the Quest 746 reduces amperage draw and frees up panel capacity for lighting and HVAC.
Features:
- Precision RH control (1% increments) for bloom and dry cycles
- Integrated lift and hang points for overhead installations
- Flexible installation options for tight cultivation spaces
- Built-in digital controls with alerts, diagnostics, and Dark Mode
- Service-friendly design with easy access to internals
- Low-GWP R454B refrigerant for a more sustainable grow
Engineered and assembled in the USA and backed by a 5-year warranty, the Quest 746 helps you maximize yield in flower and protect quality in drying for every cycle.
