Quest 506 277V High Capacity Dehumidifier

The 277V configuration offers the industry's lowest amp draw at just 8.2 amps while maintaining 500 pints/day capacity. This eliminates the need for buck-boost transformers on 277V systems, reducing installation costs and complexity while freeing up maximum electrical capacity for other equipment on your breaker.

The patented M-CoRR (Multi-Coil Refrigeration Recovery) technology uses multiple coils to recycle excess heat that would normally be wasted. This recovered heat pre-warms the incoming air, reducing energy consumption while simultaneously reducing heat output into your space by up to 30% compared to traditional designs, achieving the industry-leading 9.2 pints/kWh efficiency.

The Quest 506 277V is specifically designed for commercial and industrial facilities with 277V electrical systems. It connects directly using a standard NEMA L7-20P plug without requiring additional transformers or electrical modifications. The ultra-low 8.2 amp draw makes it ideal for maximizing available electrical capacity.

Maintenance is minimal with the Quest 506 277V. The onboard digital controls provide filter change notifications for the MERV 13 filter (typically every 3-6 months). The unit features self-diagnostics and auto-restart functionality. Ensure proper P-trap maintenance for continuous condensate drainage and periodic inspection of the drain connection.

The onboard digital controls include a dark mode setting that reduces light pollution for installations in light-sensitive environments. The low-voltage terminal block allows connection to optional remote controllers, ideal for overhead installations where direct access to controls is limited. Both features can be configured through the digital control interface.

The streamlined design eliminates the feet from previous generations, reducing overall height to 27.4" while maintaining the same performance. The compact 44.8" x 28.9" footprint with integrated handles and hanging points allows both freestanding and overhead installation in tight spaces where traditional units wouldn't fit.

R454B refrigerant has a 78% lower Global Warming Potential (GWP) compared to R410A, significantly reducing your operation's environmental impact while maintaining the same exceptional performance. This environmentally-conscious choice helps meet sustainability goals and prepares your facility for future environmental regulations without sacrificing efficiency.

The 5-year limited warranty covers manufacturing defects and component failures under normal operating conditions, including the compressor, coils, control systems, and major mechanical components. The warranty requires proper installation, maintenance, and operation within specified parameters. Consumable items like filters and normal wear parts may have shorter coverage periods.
