Storage Dehumidifier

3-Step Process

This is How It Works

The mechanism by which the Storage Dehumidifier works is two-fold as follows:
First: by means of convection and radiation the product imparts heat to nearby air molecules. Through the convection process, the Storage Dehumidifier moves 5 cubic feet of air per minute which continuously exposes volumes of air molecules to the warm (125° F, 52°C) aluminum tube. When air molecules are heated, they are capable of holding more moisture. 

Since:

Equation to obtain relative humidity

This is why in a confined storage space, if the air is heated, the relative humidity will go down. The warm air naturally rises past objects such as wood, clothes, etc. The increased moisture carrying capacity of this air draws moisture out of the objects it passes. In itself, this would not be sufficient to dehumidify the closet, as eventually, the air would become saturated and moisture would condense on objects again. This, then, is where the second mechanism comes into play.

As the air molecules are heated, they become more active and cause the pressure within the closet to increase slightly. Since most closets are not really air-tight, the increased pressure forces some of the moisture-laden air outside to be carried away. This process is repeated continually as long as the Dampp-Chaser is energized. In addition, natural convection will force the warmer air out the higher cracks, or door openings.

More simply, the Dampp-Chaser creates warmer air. This warmer air performs two functions: (1) It creates a reduced humidity level which reduces the moisture content of objects within the confined area or closet. (2) It creates air movement which acts as a vehicle to transport moisture to the outside of the closet. The actual Relative Humidity level obtained, and the actual moisture content reduction achieved will depend on the power of the Dampp-Chaser and the amount and moisture content of the air being drawn or leaking in.

STOPS mold, mildew and rust!

The Dampp-Chaser warms, dries and circulates air in the confined storage space through an around-the-clock process illustrated to the right.

STOPS musty odors!

As air in the storage area is warmed by the Dampp-Chaser, 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.
