Overview
The Quest 375 50-Hz is purpose-built for high-volume dehumidification in facilities where precision and efficiency matter most. Designed for 50Hz regions, this model is ideal for commercial grows, large drying rooms, and climate-critical industrial applications.
With Quest’s advanced M‑CoRR Technology, the 375 50-Hz delivers energy-efficient moisture removal in a more compact profile, cutting the size by 20%, while improving performance and reducing system heat output.
This model comes equipped with integrated lift and hang points for simple overhead installation. The new digital interface supports precise RH control, maintenance alerts, troubleshooting diagnostics, and dark mode for light-sensitive environments. An optional external control can be connected via the low-voltage terminal block for convenience.
Engineered and assembled in the USA and backed by a 3-year limited warranty, the Quest 375 50-Hz offers unmatched efficiency and control for demanding, large-scale environments.
