The WH120OA Professional Series Whole House dehumidifiers are compact, durable and efficient. They come standard with a remote wired digital humidity controller and are specifically designed to control excess moisture that contributes to poor indoor air quality, property damage, mold, comfort complaints, and possible liability risks. They can be used to condition living spaces, crawl spaces and other large spaces up to 30,000 cubic feet with an AHAM rated capacity (80F/60%RH) of 120 pints per day. They also come standard with a 6" motorized damper intake for bringing outdoor fresh air into your structure.

Our Professional Series dehumidifiers can be used in a variety of ways to control the humidity level in your entire home. In the simplest terms, when the humidity level exceeds the set point of the humidity controller, the dehumidifier will energize. The internal fan and compressor will turn on, forcing air to be drawn across the evaporator coil, which is cooler than the dew point of the air, allowing the coil to remove water from the air and exit via the drain. The air is then reheated as it flows across the condenser coil and distributed back into the conditioned space.

Whole House dehumidifiers are simple to install. They are connected to your central HVAC system with our standard 10" supply and return duct adapters. The unit can be controlled using the included digital wired remote control or by connecting it to your homes HVAC control system. Detailed installation configurations and options are included in our Installation and Operation Manual.
