Quest

Commercial-Grade Dehumidification for Growers

Quest dehumidifiers, produced by Therma-Stor (USA), are engineered specifically for indoor horticulture, from seedling stages to full-scale commercial operations. Built with high-efficiency refrigeration systems and energy-saving design, Quest units remove up to 706 pints/day (335 L) per model, while consuming minimal electricity, making them a staple in professional grow environments.

Constructed for grow rooms, greenhouses, and controlled environments, Quest’s overhead and ductable units feature robust build quality, ETL/UL certification, and a durable 5-year warranty from Madison, Wisconsin. Highlights include ultra-efficient coil technology, quiet operation, and designs that reduce HVAC heating load, delivering significant energy savings over time.

From the compact Quest 70 (removing 26 L/day) to the powerhouse Quest 706 (335 L/day), each model offers build-in dehumidistats, low-voltage control options, and flexible installation via overhead mounting or ducted configurations.

At Hydro Oasis, we stock Quest dehumidifiers for their unmatched reliability, energy-efficient performance, and peace-of-mind stability, perfect for growers aiming to maintain optimal humidity levels, prevent mould or mildew, and support consistent, healthy crop development from propagation to harvest.
