Quest 100 Dehumidifier — 100 Pints/Day

Struggling with humidity control in a compact space? The Quest 100 High-Efficiency Dehumidifier delivers industrial-grade performance without the large footprint, making it the perfect solution for small-scale operations, tight grow rooms, and processing areas where every inch counts.

This powerhouse removes up to 100 pints of moisture per day while maintaining incredible efficiency at 7.5 pints per kWh.

FAQs

What makes the Quest 100 ideal for small spaces?+

The Quest 100 is specifically engineered for space-constrained applications. With compact dimensions of 24" W x 14.5" H x 6" L and weighing only 60 pounds, it fits where other commercial units can't. Despite its small size, it delivers a powerful 100 pints/day capacity, making it perfect for small grow rooms, curing areas, and processing rooms.

How does the M-CoRR™ technology improve efficiency?+

M-CoRR™ (Multi-Coil Refrigeration Recovery) technology uses an advanced multi-coil design to recycle heat during the dehumidification process. This allows the unit to achieve its 100-pint capacity without overworking the system, resulting in an exceptional 7.5 pints/kWh efficiency while consuming only 540 watts. This means lower energy bills and reliable long-term operation.

What are the installation options for the Quest 100?+

The Quest 100 offers two primary installation configurations for maximum flexibility. It can be used as a freestanding unit placed on the floor with the included leveling feet, or it can be suspended overhead to save valuable floor space using the optional Quest 100 Hanging Kit.

How does this model compare to other Quest dehumidifiers?+

The Quest 100 is designed for compact efficiency. If your space requires greater moisture removal, Quest offers higher capacity models. For example, the Quest 225 removes 225 pints per day, while the Quest 335 is built for even larger commercial applications.
