Small enough to fit in almost any crawl space, the WatchDog NXT120 is one of the most compact dehumidifiers you can find. But don't let its size fool you. The WatchDog NXT120 is rated to dehumidify up to 21,000 cubic feet of space and produces 300 CFM airflow. It also features strong, durable handles for easy mobility, and easy-open access to the coil as well as the filters. Additionally, The NXT120 Series of dehumidifiers includes auto restart after a power failure, giving you one less thing to worry about.
Since crawlspaces are typically built underneath your home, they are likely to invite pests and moisture in. Although they allow you easier access to many of your pipes, other problems such as dampness and darkness are inherent. These issues often lead to mold growth, which can be very unhealthy. Over time, these issues can cause structural damage. By sealing or encapsulating your crawl space, removing any mold and mildew and installing a crawl space dehumidifier, many of these issues can be controlled.
This compact dehumidifier can operate in a wide range of temperatures from 33°F - 105°F. It also offers a wide range of Operating Relative Humidity Levels from 36% - 90%. It has a rated Condensate Capacity of 120 pints per day (at 80°F and 60% RH). The WatchDog NXT120 also features an easy to use, digital touch pad to set your desired humidity level and auto defrost.
The WatchDog NXT120 is meant to be installed in a crawl space, near your sump pump or other drainage area for the gravity drain system to function properly. A 12" drain line comes standard. The unit must be elevated to some degree to allow for water to flow through the gravity drain. It requires a 115V, 3 prong GFI outlet with a 15 amp time delay fuse. It should be placed in an easily accessible area to allow for routine maintenance. Once the dehumidifier is level, you need to direct the exhaust outlet into the desired location. Typically, you will want to choose the longest, unobstructed dimension in the crawl space. If there is a particularly damp, out of the way area of your crawl space, the warm exhaust can be vented there to help dry it out.
Maintenance is easy on this dehumidifier as well. It uses several different options of filters including MERV-10, HEPA or Carbon filters for trapping airborne particles. These filters are disposable and should be checked at least once a year. The pre-filter is washable and the MERV/HEPA/Carbon filter can easily be removed and replaced.
The Watchdog NXT120 can also be ducted. Ducting requires a 10" collar kit for both the Supply Duct and Return Duct. Ducting is optional and Duct Collar Kits are sold separately.
