The DAMP-ROD warms, dries and circulates air in confined storage spaces through a round-the-clock process. As air in the storage area is warmed by the DAMP-ROD, it expands. The expanded air causes pressure inside the storage space to be slightly higher than air pressure outside the enclosure. This pressure differential pushes stale air out of the storage area and fresh, clean air seeps in to replace the stale air. As the air is warmed, it becomes lighter and circulates throughout the storage area to keep your valuables dry. When the air cools, it drops back to the floor where the DAMP-ROD, begins the warming process again. DAMP-ROD, can be mounted horizontally on the wall near the floor or simply set it on the floor of the storage area. The area around the rod must be kept clear of any objects or clothing. Energy consumption by the DAMP-ROD, is nominal. The electrical cost is around 5 cents per day! This is approximately 3 times less than moisture absorbent chemicals which are no longer required!
