Ready for Anything
From large health spas, grow rooms, self-storage units to warehouse corners—whatever your space, the Quest 506 delivers. It’s built to thrive in a wide range of environments, and it never compromises on performance or reliability.
Smart, Space-Saving Installation
Its overhead design frees up valuable floor space, and it operates seamlessly between 56°F and 95°F. A built-in gravity drain hose makes moisture disposal easy—outdoors or to a tank. Need ducting? Optional intake and exhaust kits make it adaptable to your layout.
High-Efficiency M-CORR Technology
Quest’s patented M-CORR tech uses multiple recovery coils to maximize efficiency. It pulls 30% more water than typical dehumidifiers and uses significantly less energy, producing less heat and lowering your energy footprint.
Designed for Control and Compliance
Maintain ideal humidity levels that preserve product quality and facility integrity. Plus, the Quest 506 is Title 24 compliant, drawing only 11 amps and delivering up to 8.1 pints per kilowatt hour—making it one of the most efficient high-capacity systems on the market.
