Who This Is For

  • You are scaling up your climate control because your current setup produces too much heat while fighting humidity.
  • You are upgrading to industrial capacity because smaller units cannot keep up with the transpiration of a full canopy.

What We Found

  • The heat output is noticeably lower than other 500 pint units, which keeps your cooling system from working overtime.
  • We see fewer electrical panel upgrades with this model since it pulls less than 10 amps during peak operation.

What Users Say

  • Facilities that swapped to these report a drop in monthly power bills while maintaining tighter humidity levels.
  • Operators who switched to overhead mounting say it cleared enough floor space to add more benches for production.

Quest 506 208/230V Dehumidifier | M-CoRR High-Efficiency Moisture Removal

The Quest 506 removes 500 pints of water per day at 80°F and 60% relative humidity. It utilizes M-CoRR technology to recycle excess heat and achieve an efficiency rating of 9.2 Pints/kWh. This unit provides high-capacity moisture control for industrial dehumidifiers in commercial cultivation and large scale logistics facilities.

In Detail

The Quest 506 is engineered to handle the latent load of high-density plant canopies without excessive energy consumption. Its M-CoRR technology recycles heat within the unit to minimize the thermal impact on your cooling system. The streamlined housing lacks feet to facilitate compact overhead mounting in facilities with limited floor space. Onboard digital controls provide immediate access to set points and self-diagnostics for maintenance teams.

  • M-CoRR technology recycles excess heat for 9.2 Pints/kWh efficiency
  • Flexible 208/230V power options for industrial electrical grids
  • MERV 13 filtration captures mold, bacteria, and dust particles
  • Dark mode prevents light pollution during sensitive plant dark cycles
  • Auto Restart defaults to prior settings after a power interruption
  • Environmentally friendly R-454B refrigerant reduces GWP impact

Features

M-CoRR Technology

This multi-coil refrigeration system recycles heat to maximize moisture removal while lowering operational costs.

MERV 13 Filtration

The high-efficiency filter captures mold spores and bacteria to maintain a sterile growing environment.

Industrial Compliance

This unit is UL Rated, ETL Listed, and California Title 24 compliant for commercial facility standards.

Integrated Dark Mode

The digital display can be darkened to prevent light pollution from interfering with plant photoperiods.

Can this unit be mounted overhead?

Yes, the streamlined design is built without feet to facilitate overhead installation in tight commercial spaces.

How does M-CoRR technology affect room temperature?

M-CoRR recycles excess heat within the refrigeration cycle, which reduces the total heat output compared to standard industrial dehumidifiers.

Is the digital display safe for the dark cycle?

Yes, the integrated dark mode allows you to turn off the display lights to prevent light pollution in your grow room.

What happens if the facility loses power?

The Auto Restart feature ensures the unit automatically returns to its previous settings once power is restored.

What type of maintenance does the filtration system require?

The MERV 13 filter should be replaced regularly to maintain optimal 1,150 CFM airflow and ensure the removal of mold and bacteria.
