Open-Box: Quest 746 High Efficiency Dehumidifier

The Quest 746 480V Dehumidifier boasts their patented multi-coil design which provides industry leading efficiencies. This new unit with higher voltages uses less amperage, freeing up electricity for other equipment.

Multi-Coil Design for Unmatched Efficiency

Quest’s patented multi-coil design creates a constant curve of efficiency that delivers a consistent energy factor (kWh) even at 75 degrees F and 50% RH. Three coils work together to more effectively cool air prior to, and during dehumidification.

The first coil is filled with refrigerant and takes the edge off warm, moist air without removing moisture. When this air passes over the second coil, the evaporator drops the air temperature below dew point and water begins to be removed from it. As this air passes the third coil, energy is recovered and recycled to further improve efficiency.

Higher Voltage for Better Electrical Usage

The Quest 746 dehumidifier is a 480-volt unit which pulls only 6.5 amps of current at maximum effort. This frees up electricity for operating additional equipment. These impressive machines are also UL-rated and ETL-listed to the highest safety standards.

Beyond high efficiency and low amp draw, the Quest 746 has these features for more convenient use in a variety of applications.

• Overhead or Ground Placement: Built to fit what works for your space
• Wide Operating Range: For temperature and humidity
• MERV 13 Filtration: Superior filtration removes more harmful contaminants from the air such as dust, pollen and mold as well as bacteria and some viruses
• Integrated Handles & Hanging Points: Makes transporting and installation easy

Onboard Display & Interface

The Quest 746 features a digital display screen which can be used to view and set alarms, and can be password protected. Set the date/time, language, and activate alarms. The data logger tracks unit run hours and keeps an alarm log with the code and a short description, time & date of the trigger as well as that of the fault resolution.

Industrial and Commercial Applications

While Quest dehumidifiers may be best known for their agricultural applications, because of its superior energy efficiency and pint capacity, the 746 can be used in a number of varied environments.

• Distribution and Logistics
• Energy & Utilities
• Food & Beverage
• Manufacturing
• Inside Self-Storage
• Natural Supplements
• Science & Technology
• Sports & Recreation

Additional Features

• External Control Required: The Quest 746 needs an external remote humidistat through a 24V terminal block. Options include Quest DEH 3000R Control, or Honeywell Remote Humidistat. (Purchased separately)
• Hard-Wired: This unit does not have a cord with plug, but is hard-wire only.
• Daisy-Chain: Up to three (3) units can be daisy-chained together with a single controller.
• Gravity Drain: Condensate drains by gravity through the drain port which uses a ¾-inch male NPT PVC pipe (not included).
• Indoor Use: Designed for indoor use in a space protected from rain and flooding.

Summary

The Quest 746 480V Industrial Dehumidifier maintains consistent high-efficiency while removing up to 746 pints of moisture per day in a wide variety of applications. Its high voltage means low amp draw, freeing electricity for additional equipment operation.
