Why Choose the Quest HI-E Dry 140?
Excess humidity can create challenging conditions for commercial growing facilities, increasing the risk of condensation, mold, and moisture-related damage.
The HI-E Dry 140 helps maintain controlled humidity while reducing the electricity required for moisture removal.
Its patented M-CoRR system recovers energy during the refrigeration cycle, improving efficiency across a wide range of operating conditions.
Unlike larger stationary dehumidifiers, its portable design allows operators to move the unit between growing areas, storage spaces, and other facilities as needed.
Portable Design and Intelligent Humidity Control
The HI-E Dry 140 features an onboard digital humidistat for adjusting humidity settings and monitoring operation.
Its integrated condensate pump can discharge collected water up to 20 ft (6.1 m) above the unit, offering flexibility when gravity drainage is unavailable.
Large wheels and an adjustable handle simplify transportation, including movement over uneven surfaces. The handle also serves as a convenient dolly for compatible Quest F9 and F10 air movers.
When not in use, the compact unit can be collapsed and nested for space-saving storage.
