WatchDog 900

Product Description

The WatchDog 900 is the largest crawl space dehumidifier in the Seaira Global lineup. With a 90 pints per day capacity, the 900 is perfect for larger areas that need moisture control.

Although the Watchdog 900 is the most powerful crawl space dehumidifier offered by Seaira, that doesn’t mean it sacrifices efficiency. While producing a 370CFM airflow, the machine runs at 2.8 L/kWh and only 5.5 amps.

The WatchDog 900 also includes several convenient upgrades to make using the dehumidifier easy. For instance, when it’s time to set your desired humidity level, simply use the digital touchpad display screen. Once the set point is in place, the 900 requires minimal attention from you thanks to features like automatic humidistat control, temperature controlled defrost, and auto restart.
