ATMOX Controls and Sensors constantly measure data from inside and outside the crawlspace and input the data into the software. The system then determines the best course of action to improve conditions in the crawlspace.  The system decides whether or not to sit tight or to ventilate with the fans based on calculations of dew point inside and outside the crawlspace.  If equipped, the system can also trigger a dehumidifer if necessary but will only do so if needed to keep the system energy efficient. The software is so sophisticated it will take into account and adjust for seasonal variation and prolonged changes in temperature and humidity.  By placing fans to get a good cross circulation of air in the crawlspace, ATMOX can bring dry air to all areas of the crawlspace to reduce the moisture levels.
