Application of dehumidifiers in various industries

Application examples of dehumidifiers used to protect raw materials, finished products, and building structures:
Historical buildings
Many centuries old churches have been affected by moisture, with marble floors constantly damp, and murals and hanging paintings damaged by moisture. Mold and salt crystals appear on walls and columns, and gorgeous stained glass cannot be spared. Many attempts to repair in the past have failed. Protecting these historical relics is very important, and currently many dehumidifiers have been installed to maintain a fixed relative humidity.
After installation, the mold has been eliminated, the floor can be kept dry, and the wood is no longer bent, and the murals and paintings have also been successfully repaired.
corrosion
The corrosion phenomenon of substances can be seen as the process of one substance changing into another through chemical changes. Many corrosion reactions rely on oxygen, which can be catalyzed and accelerated by moisture.
It is well known that iron and other ferrous metals such as steel can be corroded by moisture. But few people know that glass can also be corroded and cracked by moisture. Pure crystals such as sodium iodide and lithium fluoride can also be corroded by moisture in the air to form oxides or hydroxides.
Modern society increasingly relies on computers, communication devices, and lightweight composite materials for high-energy batteries. Although it does not rust on the surface, it is sensitive to minor corrosion.

Military storage
After the Korean War in the 1950s, the US military used dry air to protect decommissioned warships, machinery, and weapons for a long time. This technology has saved millions of storage costs. In the 1970s, Europe first used hygroscopic equipment to protect military equipment in service. Today, it has been widely used worldwide, not only to reduce maintenance costs, but also to enhance the combat power of aircraft, tanks, warships, and logistics.
Electronic protection
The voltage and current used in computers and other electronic equipment are very small. When there is a corrosive layer attached to the surface of a circuit, it will increase resistance and reduce efficiency, seriously affecting its performance. Humidity control can avoid these issues and save calibration time and increase the lifespan of electronic products.
Generator set preservation
When the power plant unit shuts down due to maintenance or excessive power generation, using a dehumidifier to supply dry air to the steam turbine and power generation machinery is cheaper than filling with nitrogen and more effective than adding corrosion inhibitors or sealing with oil. The dry air method is not only simple, but also allows the machinery to quickly return to power generation work.
Lithium battery manufacturing
Lithium, plutonium, and other high-energy metals can ignite and cause harm when water vapor in the atmosphere corrodes them. The dehumidifier can control the relative humidity of its mass production area to below 1%, allowing for the mass production of lithium batteries without being expensive.

Condensation condensation
When cold surfaces come into contact with moist air, condensation can occur on their surfaces, causing some problems, such as condensation on the outer surface of display cabinet glass, which may prevent consumers from seeing the contents of the cabinet. In addition, the internal structure of the aircraft may experience condensation due to flying from high cold areas into humid airspace, which may lead to serious consequences. Dehumidifiers have been used to solve these problems. The use of condensation control is not only in solving problems, such as the low-temperature drum in the manufacturing process. If it is placed in a dry air environment, it can also increase production and reduce the occurrence of defective products.
