Taking innovation to the next level, this newest generation of the Quest 506 Dehumidifier surpasses the Quest 335 as the world’s most energy-efficient dehumidifier on the market, removing 500 pints per day at an impressive 9.2 pints per kilowatt hour (at 80°F, 60% RH).
Just like the original 506 design, the 500-pint capacity makes it one of the most powerful commercial dehumidifiers on the market. The 277 V voltage provides a low amp draw, freeing up electricity for other equipment on your breaker. Best of all, these units can be installed on 277 V without the additional installation of buck-boost transformers or the associated costs of rewiring.
The impressive energy efficiency is a result of Quest’s patented M-CoRR™ technology. Their unique multi-coil refrigeration design recycles excess heat to provide the highest efficiencies available on the market, while reducing heat (BTU) output into your space.
You’ve been asking for it and they delivered: the new generation of Quest 506 now features Quest’s onboard digital controls. This user-friendly control panel allows for easy set points, self-diagnostics, filter change notifications, and dark mode, limiting light pollution. Additionally, the user interface features a low-voltage terminal block to utilize a remote controller, ideal for overhead installations.
Built on years of real-world feedback and observation, it was clear that most of these high-capacity units were installed overhead and in tight spaces. That insight drove their engineers to rethink the design, eliminating the feet from the previous generation to create a more compact, space-saving solution. The result? The new Quest 506 277V dehumidifier fits seamlessly into your environment with less height, and without compromising performance.
The Quest 506 now utilizes the environmentally friendly refrigerant R-454B. It boasts a significantly lower Global Warming Potential (GWP) compared to the previously used R-410A, and the common R-32A found in many competitor machines. Switching to R-454B represents a crucial step forward in reducing the environmental impact of the world, and your business. By choosing a dehumidifier with a lower GWP refrigerant, you’re not only improving air quality and moisture control but also contributing to a more sustainable future. Designed to meet stringent environmental standards while maintaining exceptional performance, their upgraded product line delivers the reliability you trust with the added benefit of reduced greenhouse gas emissions.
Proudly engineered and assembled in Madison, Wisconsin, the Quest 506 277 V is designed to deliver unmatched reliability and efficiency. Accordingly, this unit meets California Title 24 energy requirements for both ducted (whole-home) and non-ducted (portable) installations.
