205 High Efficiency Overhead Dehumidifier by Quest, M-CoRR

The Quest 205 removes up to 200 pints of moisture per day on 110-120V power, using a MERV 13 filter and Quest's patented M-CoRR multi-coil refrigeration design. It's positioned close to the 225 in overall capacity, but runs on standard 110-120V rather than 208/230V service.

That voltage difference matters for facilities without three-phase or higher-voltage service already run to the installation point, letting operations get 205-class capacity on the same electrical infrastructure as Quest's smaller overhead units.

Key Features & Benefits

• 200 pints/day capacity — on standard 110-120V power, close to the Quest 225's capacity but on lower-voltage service.
• Patented M-CoRR multi-coil refrigeration — recovers heat generated during the dehumidification cycle and puts it back to use, lowering both energy draw and the added heat load in the space.
• MERV 13 filtration — screens out up to 95% of dust, mold spores, bacteria, and smoke moving through the unit.
• Standard 110-120V operation — avoids the need for 208/230V or higher-voltage electrical service some comparable-capacity units require.
• Overhead-mount design — keeps floor space clear in the grow room.

Who Should Use This

The Quest 205 suits commercial growers who need capacity close to the 225 but whose facility runs standard 110-120V service rather than 208/230V, avoiding the cost of upgrading electrical infrastructure just to add dehumidification capacity.

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 205 differ from the Quest 225?

Both are similarly sized in the Quest overhead lineup, but the 205 runs on standard 110-120V power while the 225 requires 208/230V. If your facility already has 208/230V service, the 225's slightly higher rated capacity may be the better fit; if you're limited to 110-120V, the 205 is the closer match.

What electrical service does the Quest 205 need?

It runs on standard 110-120V power, which many facilities already have available without upgrading their electrical infrastructure. Confirm your circuit's amperage rating against the unit's nameplate before installation.

Does M-CoRR technology perform differently at 110-120V than at 208/230V?

The multi-coil refrigeration design recycles heat from the dehumidification process the same way regardless of voltage; the electrical service simply determines how the unit is wired into a facility, not the underlying heat-recycling mechanism. Energy efficiency gains from M-CoRR apply consistently across Quest's M-CoRR-equipped models.

How much filtration does the MERV 13 filter provide on this unit?

It filters out up to 95% of dust, mold spores, bacteria, and smoke from the air passing through. Replace it on the manufacturer's recommended schedule to keep airflow and filtration performance at the unit's rated level.
