The ATMOX system is a smart, sensor-driven approach to crawl space moisture control. At its core are intelligent controllers that monitor temperature and humidity both inside and outside the crawl space. When outside conditions are favorable, the system briefly activates fans to exchange air, then closes again to maintain the sealed environment. When conditions call for active drying, the controller can trigger a connected dehumidifier automatically. Crawlspace Depot carries the full ATMOX product line: control sets, crawl space fans, temperature and humidity sensors, wood moisture sensors, water alert sensors, dehumidifier relay kits, low-voltage wiring, power adapters, and LED crawl space lighting. Every component works together as part of a complete crawlspace encapsulation system designed to keep your crawl space dry and your home healthy.
