Overhead Dual 110 Dehumidifier by Quest for Grow Rooms

The Quest Dual 110 removes up to 110 pints of moisture per day on 115V power at 7.4 amps, and it's built to work either as a portable floor unit or an overhead-mounted one -- the same unit covers both installation styles rather than forcing a choice at purchase time.

It's positioned as Quest's smallest and lightest mid-size model, which matters for facilities weighing overhead mounting against ceiling load limits. It's also California Title 24 compliant for ducted installations, relevant for any commercial cultivation project subject to that code.

Key Features & Benefits

• 110 pints/day capacity — on 115V power at 7.4 amps, sized for standard commercial circuits.
• Dual-mount design — works as either a portable floor unit or an overhead-mounted unit, so the installation approach can change without swapping equipment.
• Smallest and lightest in its mid-size class — a lighter unit simplifies overhead mounting where ceiling load capacity is a limiting factor.
• MERV 8 filtration — captures common airborne particles at a rating matched to this unit's blower design.
• California Title 24 compliant for ducted installations — relevant for commercial cultivation projects in jurisdictions that enforce this energy code.

Who Should Use This

The Dual 110 suits mid-size cultivation operations that want the flexibility to run the unit on the floor initially and move it overhead later, or vice versa, and California-based commercial projects that need Title 24 compliance for ducted installations.

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

Can this unit really be used both on the floor and overhead?

Yes, it's designed to work in both configurations, using the appropriate Quest hang kit or duct kit accessories for an overhead installation. That flexibility lets an operation change its mounting approach later without replacing the dehumidifier itself.

What does California Title 24 compliance mean for this unit?

Title 24 is California's energy code, and this unit is compliant for ducted installations under that code. If you're installing in California, confirm the specific Title 24 requirements applicable to your project type with your local permitting authority.

How much power does the Dual 110 draw?

It runs on 115V power at 7.4 amps, drawing 110 pints/day of moisture removal capacity from that power draw. Confirm your circuit capacity, especially if running multiple units on a shared electrical panel.

Why does Quest describe this as its smallest and lightest mid-size model?

Within Quest's mid-size dehumidifier lineup, the Dual 110 has the lowest weight and smallest footprint, which is specifically relevant for overhead mounting where a lighter unit reduces the structural load on the ceiling or support. It's a meaningful factor for facilities with tighter ceiling weight limits.
