Quest 155 Overhead Dehumidifier with M-CoRR Technology — 155 Pints/Day 110-120VAC

155 Pints Per Day with Patented M-CoRR Technology — High-Efficiency Overhead Dehumidification on 120VAC Power

High-capacity overhead dehumidification on standard 120VAC power is a practical advantage for grow operations that need serious moisture removal without upgrading their electrical infrastructure. The Quest 155 Overhead Dehumidifier delivers up to 155 pints of moisture per day at 500 CFM and 8.5 pints per kilowatt hour — among the highest energy efficiency ratings available in its capacity class — using patented M-CoRR Technology to reduce operational energy costs significantly compared to comparable fixed-efficiency dehumidifiers.

M-CoRR (Modulating Compressor Refrigerant Regulation) Technology allows the Quest 155 to modulate its compressor output based on actual environmental conditions, running at optimal efficiency rather than at a fixed maximum. This results in both more precise humidity control and lower electricity consumption over the course of a full grow cycle — a meaningful cost difference in operations running dehumidifiers 24 hours a day through multiple harvests per year. The unit produces 9,700 BTU of heat output, which should be factored into facility cooling load calculations.

At 20% smaller than its predecessor, the Quest 155 installs cleanly in overhead positions using integrated hanging points, or on the ground when ceiling-mounted placement isn't practical. A removable access panel simplifies filter maintenance, and the long power cord and auto-restart functionality support flexible, unattended operation. MERV 13 filtration — the highest in any grow room dehumidifier in this class — captures a broader spectrum of airborne particulates including fine dust, pollen, and mold spores. Engineered and assembled in Madison, Wisconsin and backed by a 5-year warranty.

Key Features & Benefits

• Patented M-CoRR Technology for Lower Operating Costs — Modulating compressor output reduces energy consumption compared to fixed-efficiency dehumidifiers at equivalent capacity, delivering significant cost savings in facilities running continuous dehumidification year-round.
• 8.5 Pints/kWh Energy Efficiency — Among the highest efficiency ratings in its capacity class on 120VAC power, allowing high-capacity moisture removal without the energy penalty typical of older dehumidifier technology.
• 155 Pints/Day at 500 CFM on 110-120VAC — Delivers industrial-class capacity on standard 120VAC power, making it accessible to grow operations that cannot cost-effectively upgrade to 208/240VAC electrical infrastructure.
• MERV 13 Filtration — Higher filtration efficiency than MERV 11 alternatives, capturing finer particulates including fine dust, pollen, and mold spores — providing superior crop and equipment protection in active grow environments.
• 20% Smaller Than Predecessor — Compact overhead profile takes up less ceiling space and allows more flexible placement within the grow room, with integrated hanging points for straightforward overhead installation.
• Auto-Restart and Long Power Cord — Auto-restart resumes operation at the pre-set conditions after a power interruption without manual intervention. The extended power cord provides installation flexibility for outlets not immediately adjacent to the mounting location.
• 5-Year Warranty — Assembled in Madison, WI — Quest's 5-year warranty and domestic assembly provide long-term reliability assurance for commercial grow operations where equipment downtime directly affects crop quality and revenue.

Who Should Use the Quest 155

The Quest 155 is the right dehumidifier for grow operations that need high-capacity overhead dehumidification on 120VAC power — particularly facilities where upgrading to 208/240VAC is not practical or cost-effective. It is well-suited for mid-size commercial grow rooms, serious home cultivators with dedicated grow spaces, and operations where MERV 13 air quality filtration is a priority. Facility managers focused on long-term energy cost reduction will find M-CoRR Technology a meaningful differentiator compared to fixed-efficiency alternatives in this capacity range.

Frequently Asked Questions

What is M-CoRR Technology and how does it reduce operating costs?

M-CoRR stands for Modulating Compressor Refrigerant Regulation. It allows the Quest 155's compressor to modulate its output based on the actual humidity load in the environment rather than running at a single fixed speed. When humidity is high, the compressor runs harder; when conditions stabilize near the setpoint, it scales back. This reduces energy waste from running at maximum output when it isn't needed — the primary source of inefficiency in fixed-speed dehumidifiers. Over a full year of continuous operation, this can result in significant utility cost savings.

Why does the Quest 155 have MERV 13 filtration instead of MERV 11?

MERV 13 captures a broader range of particulate sizes than MERV 11, including fine dust, mold spores, and pollen in the 1-3 micron range that MERV 11 filters allow to pass through. In active grow environments where mold pressure and particulate loads are a concern, MERV 13 filtration provides superior air quality protection for both plant canopies and internal dehumidifier components. The Quest 155 is the only unit in its class to include MERV 13 filtration as standard.

How does the Quest 155 compare to the Anden A130 at similar capacity?

Both units operate near 130-155 pints per day and target commercial grow environments, but they differ in power requirements and design approach. The Anden A130 runs on 120VAC at 920W and emphasizes cultivation-specific features including smart control integration and overflow protection. The Quest 155 runs on 110-120VAC and delivers 8.5 pints/kWh efficiency via M-CoRR Technology with MERV 13 filtration and a compact overhead profile. The Quest 155 is generally preferred when energy efficiency and filtration quality are the primary selection criteria; the Anden A130 is preferred for smart control ecosystem integration.

What is the replacement filter for the Quest 155?

The Quest 155 uses a dedicated replacement filter available separately. Contact your distributor or Quest's support resources for the specific replacement filter part number compatible with your unit. Replace per Quest's recommended maintenance schedule to maintain full airflow and filtration efficiency.
