Quest 746 High-Capacity Dehumidifier

Description

Engineered for Performance: The Quest 746 480V Dehumidifier

The Quest 746 dehumidifier brings a new level of efficiency with its patented multi-coil technology—designed to do more while drawing less power. Thanks to its 480-volt system, it operates at just 6.5 amps, conserving electricity for your other equipment and applications.

Why Multi-Coil Matters

At the heart of the Quest 746 is its unique triple-coil design, engineered for consistent performance even at 75°F and 50% relative humidity. Here’s how it works:

• Coil One: Pre-cools the incoming warm, humid air.
• Coil Two: Drops the temperature below the dew point, allowing moisture to condense and be removed.
• Coil Three: Recovers and reuses energy, boosting overall system efficiency.

This system delivers a smooth curve of energy performance and meets the latest California Title 24 standards for both ducted and overhead installations.

Efficient Power Use

This 480V unit runs efficiently with minimal amp draw, leaving room in your circuit for additional machines or devices. UL-rated and ETL-listed, the Quest 746 meets strict safety standards without compromising capability.

Smart Design for Versatile Installations

From warehouses to wellness spaces, the Quest 746 adapts to your setup:

• Place it on the ground or mount it overhead—your space, your rules.
• Operates across a broad range of temperatures and humidity levels.
• Built-in MERV 13 filtration traps airborne particles including dust, pollen, mold, bacteria, and even select viruses.
• Integrated handles and hanging points make installation straightforward.
• A digital control panel provides intuitive monitoring with options for alarms, password protection, and real-time system stats.
