The 506 208/230V features a versatile design with integrated handles and suspension points, allowing for flexible installation options, such as overhead mounting. Its operational temperature range of 56°F to 95°F ensures reliable performance across diverse settings and applications. Engineered and assembled in Madison, Wisconsin, the unit is compliant with California Title 24 energy efficiency standards for ducted and non-ducted installations, meeting stringent regulatory requirements.

Safety and durability are prioritized with UL and ETL certifications, while an auto-restart feature ensures uninterrupted operation after power outages. Backed by a 5-year warranty, the Quest 506 208/230V is a dependable, energy-efficient solution for controlling humidity in demanding industrial, commercial, and agricultural spaces, providing users with confidence in its reliability and long-term performance.
