Quest 155 High-Efficiency Dehumidifier

Description

Stop Moisture Damage Before It Starts — Protect Your Commercial Space with the Quest 155

Mold, mildew, and excess humidity can quietly wreak havoc on your plants, property, and bottom line. The Quest 155 Overhead Dehumidifier is built to help you stay ahead of moisture issues in health clubs, grow rooms, warehouses, and indoor environments where air quality matters most.

High Performance, Low Maintenance

With the ability to remove up to 155 pints of moisture daily, this powerhouse unit keeps your air dry, clean, and balanced—without eating up valuable floor space. Installation is flexible: mount it overhead, duct it into multiple rooms, or place it directly on the ground. Either way, setup is plug-and-play.

Smarter Tech for Better Efficiency

Powered by Quest’s patented M-CORR™ technology, this commercial-grade dehumidifier extracts more water with less energy—cutting utility costs while boosting performance. It’s also CA Title 24 compliant, making it a smart, eco-conscious investment.

Scale with Confidence

Managing larger or multi-zone spaces? You can link up to six units using the Quest DEH 3000R controller. Ideal for growing operations, retail, schools, restaurants, or any space that depends on reliable climate control.

Humidity Control Made Simple

Set your desired relative humidity—Dry (20–30%), Normal (50%), or Humid (80–90%)—and let the onboard humidistat do the rest. It automatically kicks in when needed and shuts off once the air is balanced.
