Overview
Powerful moisture control. plug-and-Play design.
The Quest 100 50Hz is engineered for precision dehumidification in tight environments that demand consistent performance. Designed exclusively for 50Hz markets, this compact solution is ideal for small grow rooms, dry rooms, storage units, and other climate-sensitive spaces where every square meter matters.
Featuring patented M‑CoRR Technology, the Quest 100 50Hz is built for performance — removing 44 litres of moisture per day (at 26.7°C/60% RH) with industry-leading energy efficiency in a footprint that’s 20% smaller than traditional systems. It’s an ideal fit for facilities with limited space.
Unlike traditional dehumidifiers, its internal drainage system eliminates the need for a P-trap, making installation faster and easier. Its compact size and corrosion-resistant base make the Quest 100 ideal for moist commercial and industrial spaces.
With intuitive digital controls, the Quest 100 offers accurate relative humidity management, helpful maintenance alerts, diagnostic insights, and dark mode to reduce light in sensitive zones.
The Quest 100 50Hz is your no-hassle solution for reliable, industrial humidity control.
Engineered for ease. Built to perform.
Engineered and assembled in the USA, Quest products are backed by a reputation for reliability with high quality components.
Not in a 50hz region? This model is also available for 60hz regions.
