The Quest 165 High-Efficiency Dehumidifier is a long-term solution for industrial and commercial moisture removal. This American-engineered unit removes up to 165 pints of moisture (AHAM). Commonly used in warehouses, indoor grow rooms, gyms, factories, and plants, its versatile design provides options for ducting, installation, and remote humidistat use.

Note: This 220-240 volt dehumidifier can be plugged in or wired to multiple units. The included plug is a NEMA 6-15P plug with 10-foot power cord.

Better Humidity Control

This high-efficiency dehumidifier can be controlled using its onboard dehumidistat or, if remote operation is needed, with an external controller. Easy-to-use humidistat features a manual dial for creating the right set point for your needs. Use Dry (20-30% humidity), Normal (50% humidity), Humid (80% humidity). To control your dehumidifier remotely or to control multiple units from one place, use the Quest DEH3000 R.

Daisy Chain Option

For easier wiring to an external control, this dehumidifier features a low voltage terminal block. This wiring system allows for space-saving overhead installation as well as daisy-chain wiring. Connect up to six of these models together for use in large warehouses, line-work in plants, gyms, schools, and many other industrial or commercial applications.

All six will be operating from the same sensor on the Quest DEH 3000 R and will need to be in the same room.
