225 High Efficiency Overhead Dehumidifier by Quest, M-CoRR

The Quest 225 removes up to 225 pints of moisture per day at 630 CFM and 14,400 BTU on 208/230V power, sitting in the middle of Quest's overhead commercial dehumidifier lineup between the 100 and the larger 335 and 506 models.

Like Quest's other M-CoRR-equipped units, it recycles heat pulled from the air during dehumidification through its patented multi-coil refrigeration design, cutting energy use and limiting the amount of heat added back into the grow room. A MERV 13 filter captures up to 95% of common airborne particles passing through the unit.

Key Features & Benefits

• 225 pints/day capacity — at 630 CFM and 14,400 BTU on 208/230V power, a mid-capacity step up from Quest's 100 and 155 models.
• Patented M-CoRR multi-coil refrigeration — pulls heat from the air during dehumidification and recycles it back in, cutting energy use and reducing the load on the room's cooling system.
• MERV 13 filtration — removes up to 95% of dust, mold spores, bacteria, and smoke as air passes through the unit.
• 208/230V operation — matched to standard commercial electrical service without requiring the hard-wire installation Quest's largest units need.
• Overhead-mount design — keeps floor space clear in a mid-to-large commercial grow room.

Who Should Use This

The Quest 225 fits commercial growers needing more capacity than Quest's entry-level overhead units but not yet at the scale that calls for the 335 or 506, particularly operations on standard 208/230V service who want M-CoRR energy efficiency at this capacity range.

About Quest

Quest is a Therma-Stor brand. It focuses on commercial dehumidification. Therma-Stor is headquartered in Madison, Wisconsin. It's the same parent company behind the Anden brand. Therma-Stor has built dehumidifiers and environmental-control equipment for decades. Quest specifically targets commercial and industrial moisture control. Think indoor cultivation, food production, and commercial buildings. That's a different focus than residential basement units. Many overhead models use the company's patented M-CoRR design. M-CoRR stands for multi-coil refrigeration. The design recycles heat pulled from the air. That happens during dehumidification itself. It improves energy efficiency as a result. It also cuts heat sent back into the room.

Frequently Asked Questions

How does the 225 compare in capacity to Quest's other overhead models?

At 225 pints/day, it sits above the Quest 100 and 155 but below the 335 and 506 in Quest's overhead M-CoRR lineup. Choosing between them should come down to your space's actual moisture load rather than simply picking a mid-range number.

What electrical service does the Quest 225 require?

It runs on 208/230V power, standard commercial service that doesn't require the hard-wire installation Quest's largest units like the 876 need. Confirm your facility's electrical service matches this voltage before ordering.

What particles does this unit's MERV 13 filter capture?

It captures up to 95% of airborne particles including dust, mold spores, bacteria, and smoke, the same filtration standard used across several other Quest overhead models. The physical filter is sized specifically to the Quest 225's housing, so order the compatible replacement rather than a filter meant for a different model.

Does M-CoRR technology work the same way on this unit as on Quest's larger models?

Yes, the patented multi-coil refrigeration design recycles heat pulled from the air during dehumidification regardless of the unit's overall capacity, reducing both energy use and the heat load added to the room. The mechanism scales with the unit, but the underlying technology is consistent across Quest's M-CoRR-equipped lineup.
