Applications
Corrosion protection
​
All materials corrode, which is to say every substance eventually changes from one form to another through chemical reactions. Many of these reactions, especially those which depend on oxygen, are catalyzed and accelerated by moisture. Desiccant systems save owners literally hundreds of millions of dollars each year by preventing corrosion.
Common Applications:
-
Galvanized steel strip and wire storage
-
Long term storage of military equipment
-
Airplanes and helicopter storage
-
Lithium battery and chip production
-
Power plant equipment rust prevention
-
Protection of bridge girders, mild steel components and high tensile support wires
-
Turbine blades manufacturing and storage
-
Lightweight composite materials
-
Computers and telecom equipment
Mold and Fungus prevention
​
Mold and fungus are present in almost all materials. They can survive without moisture, remaining dormant for decades, even centuries. But when moisture and a food source become available they will multiply rapidly. This moisture does not have to be in liquid form. Microscopic organisms can use moisture present in solid materials because they need so little.
Common Applications:
-
Grain storage
-
Museum storage rooms
-
Fabrics and textile storage
-
Wooden sculpture preservation
-
Wine cellars
-
Food powder storage
-
Cannabis indoor production in controlled room environment.
-
Cocoa beans and tea leaves storage
-
Yeast production
Condensation protection
​
Condensation can lead to a number of problems. For example it can form on hidden aircraft structural members as a plane descends from the cold upper atmosphere into moist environments. This can accelerate stress corrosion and shorten the life of the air-frame. Dehumidifiers prevent condensation by 'shielding' cold surfaces with dry air.
Critical environment for lithium ion battery manufacturing
​
Lithium is very sensitive to moisture and can react violently even with relatively low humidity levels in the air or the moisture in other substances, releasing hydrogen gas, which may catch fire explosively. Therefore the manufacturing of lithium batteries takes place in ultra low humidity dry rooms.
Common Applications:
-
Ice rinks
-
Circuit board storage
-
Refrigerated display cases
-
Water treatment plants
-
Telecom equipment and chip production
-
Injection molding
-
Cold product receiving rooms
-
Airplane landing gear and frame components
Steady Dew points down to -40°F
Low dew point desiccant dehumidifiers manufactured by Seibu Giken achieve the very dry air required for safe and efficient lithium batteries production. Desiccant dehumidifiers designed to achieve and keep steady humidity levels, down to -40°F dew point (less than 1% RH) in the controlled space.
Product drying
​
Most products are dried using hot air to vaporize moisture and carry it away. Often, however, hot air is either too slow or results in damage to the product. Enzymes, for instance, are destroyed by heat, and if yeast is dried with very hot air, it cannot work properly. The range of product drying applications for dehumidifiers has expanded significantly in recent years.
Common Applications:
-
Photographic film manufacturing
-
Instant coffee creamer
-
Pharmaceutical powders
-
Sugar substitutes
-
Cannabis purpose-built indoor
modular grow rooms -
Low-moisture welding rods
-
Tomato powder
-
Prosciutto ham, hard sausage
-
Potato flakes, grated cheese
-
Paint pigment, glass powder
Dry cooling
​
Air conditioning systems generally use cooling coils to control both air temperature and humidity. In some circumstances, there is a benefit to adding a desiccant dehumidifier to the cooling system to control humidity separately from air temperature. The benefits are greatest where the moisture loads are high compared to the sensible heat loads.
