The Dual 225 was built to answer the voltage concerns of commercial users. Almost as efficient as our Dual 155 model, the Quest Dual 225 is a favorite among those who choose the higher voltage route.

Commercial spaces like warehouses, gyms, indoor gardens and plants need the power of the Quest Dual 225 Overhead Dehumidifier. As the industry’s 230-volt commercial dehumidifier, this unit is capable of removing up to 225 pints of water under AHAM conditions, features an onboard dehumidistat for automatic humidity regulation, and more.

For large areas, you can also daisy chain multiple units, controlling them with one remote dehumidistat. Multiple installation options, including ducting or not ducting, allow for versatile moisture removal anywhere you need it.

Onboard Dehumidistat

Capable of monitoring humidity levels inside grow rooms and greenhouses, the Quest 225 efficiently removes accumulated moisture from the air resulting from watering and feeding.

The onboard dehumidistat can be preset to 3 different settings – dry, normal, and humid. When the humidity rises above your preset, it will automatically kick on the dehumidifier, running the unit until the humidity falls below 4% -6% relative humidity. Once the desired level has been achieved, it the unit will shut down.

Plug & Play and Overhead Installation

Putting in the Quest Dual 225 is easy with two preferred methods to installation: overhead (recommended) and ground installation.

• Ground Installation:

  The simple ground or floor installation is the Plug & Play, allowing for easy accessibility to the unit and selecting the preferred humidity levels on the onboard dehumidistat.

• Overhead Installation:

  The recommended installation method, the overhead suspension is a great alternative when floor space is needed. This solution is also great for capturing trapped heat and humidity lingering at near the ceiling. Install the dehumidifier using Quest hanging brackets for ceiling suspension.

Best Practices to Reuse Condensate Water

Quest dehumidifiers produce very low TDS water with neutral pH. This water is safe to reuse for all plants, even consumable ones. To get the most out of this feature:

• Run your dehumidifier if it's been idle first:

  If your dehumidifier has been sitting idle, run it for three days before using any condensate water from it. (Dehumidifiers that are allowed to sit for more than a couple of days should be dried out as completely as possible, to discourage mold growth.)

• Test condensate - Be sure it's free of contaminates:

  Contaminate levels should be low enough and well within acceptable limits as long as your dehumidifier is in good working order and has proper filtration. It is always a good idea to test condensate water for heavy metals, nitrates, and bacteria – and state law may require you to if you are a commercial grower.

• Keep your dehumidifier and filter clean:

  Quest dehumidifiers will produce condensate water that can be used as-is, as long as you keep the filter in place and clean regularly. Dust, bacteria, and other pollutants can contaminate condensate water if the dehumidifier's filter is absent or not maintained properly.

• Keep your dehumidifier running continuously and recycling water:

  Why? Because just using and reusing condensate water over and over again keeps it clean. Only if you always use a high-quality, clean air filter during operation, the constant recycling of the dehumidifier's condensate water discourages mold growth. Keep the filter in place, and follow the filter guidelines for it; clean or replace the filter as directed.
