Who This Is For

  • You are upgrading to high-efficiency dehumidification because your energy bills spike during heavy humidity cycles.
  • You are switching to overhead mounting because floor space is limited and you need clear walkways for crop work.
  • You are moving to MERV 13 filtration because ambient dust and mold spores are threatening your final crop quality.

What We Found

  • The 120V plug is a game changer because it lets you drop this in anywhere without calling an electrician.
  • We love the overhead hang points since they clear up floor space for benches and easier foot traffic.
  • The side access panel is actually useful because you can swap filters without taking the whole unit down.

What Users Say

  • Operators who switched to overhead mounting say they stopped tripping over drain lines in their tight aisles.
  • Users who installed this unit report that their power bills dropped significantly due to the 8.5 pints/kWh rating.
  • Facilities that integrated the MERV 13 filters say they see far less dust buildup on their finished harvest.

Quest 155 High Efficiency 155 Pint Dehumidifier | Patented M-CoRR Technology

The Quest 155 is a high-capacity refrigerant dehumidifier engineered for commercial grow environments where energy efficiency and space optimization are critical. It removes 155 pints of water per day while maintaining an industry-leading efficiency of 8.3 pints per kilowatt-hour. This unit provides facility managers with a scalable solution that meets strict energy codes without sacrificing moisture removal throughput.

In Detail

Quest 155 High Efficiency 155 Pint Dehumidifier in use

The Quest 155 utilizes patented M-CoRR technology, a multi-coil refrigeration design that recycles energy to maximize water removal while minimizing heat output. This system allows the unit to operate efficiently across a wide temperature range; it remains effective between 56 and 95 degrees Fahrenheit. Its compact footprint and integrated hang points facilitate overhead installation, preserving floor space for benches and irrigation systems.

  • Patented M-CoRR technology recycles heat to improve energy factor.
  • MERV 13 filtration removes particles down to 0.3 microns.
  • Onboard digital controls allow for precise humidity setpoints.
  • California Title 24 compliance ensures eligibility for utility rebates.
  • Auto-restart function resumes operation immediately after power interruptions.

Features

M-CoRR Technology

The multi-coil refrigeration system recycles energy to remove more water per kilowatt than standard refrigerant models.

MERV 13 Filtration

High-grade pleated filters capture mold spores and pollen to protect the health of your crop and the longevity of the coils.

Overhead Mounting

Integrated hang points allow for ceiling installation to maximize vertical space and improve airflow distribution.

Easy Serviceability

A removable access panel provides direct entry to internal components for filter changes and routine maintenance.

Frequently Asked Questions

Is the hanging kit included with this unit?

No, the Quest 155 features integrated hang points but requires a separate hanging kit for ceiling installation. You can add the compatible Quest 100 Hanging Kit to your order to facilitate overhead mounting.

How do I maintain the unit if it is installed overhead?

The unit is designed with a removable access panel that allows you to change the MERV 13 filter and inspect internal components without removing the unit from its mounts. This simplifies routine maintenance in tight ceiling spaces.

Does this dehumidifier require a condensate pump?

The Quest 155 uses a standard 3/4 inch threaded NPT drain port for gravity drainage. If your facility does not have a floor drain nearby or requires water to be pumped upward, an external condensate pump will be necessary.

How does the M-CoRR technology affect my utility costs?

M-CoRR technology recycles heat within the refrigeration cycle, allowing the unit to pull 155 pints of water while using only 750 watts. This high efficiency rating of 8.3 pints/kWh directly lowers operational utility costs compared to standard commercial dehumidifiers.

Will this unit restart automatically after a power failure?

Yes, the Quest 155 includes an auto-restart function. It will resume operation at its previous settings immediately once power is restored to the facility.

Is this unit compliant with California Title 24?

Yes, the Quest 155 is fully compliant with California Title 24 energy standards. This compliance makes the unit eligible for many commercial energy efficiency rebates offered by utility providers.
