Quest 506 208/230V High Capacity Dehumidifier

Are excessive humidity and rising energy costs compromising your large-scale operation? The Quest 506 208/230V Dehumidifier delivers the ultimate solution, combining massive moisture removal with unparalleled energy efficiency. This unit is one of the most powerful industrial dehumidifiers in its class, engineered to tackle the toughest environmental challenges.

The Quest 506 removes an incredible 500 pints of water per day while achieving an exceptional 9.2 pints per kilowatt-hour (Pints/kWh) efficiency rating. Its patented M-CoRR multi-coil refrigeration technology recycles excess heat to maximize performance, significantly reducing the heat output into your space. Operating at just 9.9 amps at 230V, it provides more dehumidification capacity per amp than competitors, freeing up valuable electrical capacity for other equipment. The entire Quest lineup is known for this level of performance, with smaller options like the Quest 335 available for different needs.

Built for versatility, the Quest 506 operates effectively across the industry's widest temperature range (56°F to 95°F), ensuring consistent performance. Engineered and assembled in Madison, Wisconsin, this unit features superior MERV 13 filtration, environmentally-conscious R454B refrigerant, and meets California Title 24 compliance standards. For operations with even greater demands, the Quest 876 offers a significant step up in capacity.

FAQs

How does the Quest 506's M-CoRR technology actually work to improve efficiency?+

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 the energy needed for the dehumidification process while simultaneously reducing heat output into your space by up to 30% compared to traditional designs.

Is the Quest 506 208/230V suitable for my operation size and space?+

The Quest 506 is designed for large commercial and industrial applications. With 500 pints/day capacity and 1,150 CFM airflow, it's ideal for spaces up to 10,000+ cubic feet. Its compact footprint allows both floor and overhead installation. For a detailed comparison, check out our complete guide to Quest dehumidifiers to find the perfect model for your needs.

What daily maintenance does the Quest 506 require?+

Daily maintenance is minimal. The onboard digital controls provide filter change notifications, and the MERV 13 filter typically requires replacement every 3-6 months depending on environmental conditions. The unit also features auto-restart functionality and self-diagnostics to minimize manual intervention.

What makes the flexible voltage capability beneficial?+

The 208/230V flexibility allows installation on either voltage system without equipment modifications. This reduces installation complexity and costs while providing lower amp draw (9.9A at 230V, 10.9A at 208V) compared to previous generations, freeing up electrical capacity for other equipment.

How do I use the remote control capability for overhead installations?+

The Quest 506 features a low-voltage terminal block that connects to optional remote controllers. This allows you to adjust settings, monitor performance, and receive alerts from ground level when the unit is mounted overhead, providing convenient access for daily operations.

What environmental benefits does the R454B refrigerant provide?+

R454B refrigerant has a 78% lower Global Warming Potential (GWP) compared to the commonly used R410A, significantly reducing your operation's environmental impact. This newer refrigerant maintains high performance while meeting stringent environmental standards.

What is covered under the 5-year warranty?+

The 5-year limited warranty covers manufacturing defects and component failures under normal operating conditions. This includes the compressor, coils, and major mechanical components. The warranty requires proper installation and maintenance as outlined in the user manual. Consumable items like filters are not covered.
