This article details the application of the rotary dehumidifier in various occasions:

Historic Buildings

Many centuries-old churches have been damaged by moisture. The marble floors are wet all the year round. The murals and paintings are destroyed by moisture. The mold and salt crystals appear on the walls and columns, and the gorgeous stained glass is not spared. Many attempts to fix in the past have failed. It is very important to protect these historical artifacts. At present, a moisture absorber dehumidifier has been installed to maintain a fixed relative humidity. After the installation, the mold was removed, the floor remained dry, the wood was no longer bent, and the murals and paintings were successfully restored.

corrosion

Corrosion of matter can be seen as the process by which a substance changes from chemical to another. Many corrosion reactions must rely on oxygen, which can be catalyzed and accelerated by moisture.

Iron metal such as iron and steel is known to 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 is increasingly relying on computers, communication equipment and lightweight composite high-energy batteries. Although it does not rust, it is sensitive to minor corrosion.

Military storage

After the Korean War in the 1950s, the US military used dry air to protect the warships, machinery, and weapons that were suspended for a long time. This technology saves millions of savings. In the 1970s, Europe first used moisture absorbent equipment to protect military equipment in service. Today, the world has been widely used, in addition to reducing maintenance costs, but also to improve the aircraft, tanks, warships and logistics.

  Electronic protection

The voltage and current used by computers and other electronic equipment are small. When the surface of the circuit has a corrosion layer attached, it will increase the resistance reduction performance and seriously affect its performance. Humidity control avoids these problems and saves calibration time and increases the life of electronic products.

  Generator set storage

When a power plant unit is shut down due to maintenance or overcapacity, the use of a dehumidifier to supply dry air to the steam turbine and the power generation machine is less costly than filling nitrogen and is more effective than adding corrosion inhibitors or sequestering with oil. The dry air method is not only simple, but also allows the machine to quickly return to power generation.

Lithium battery manufacturing

Lithium, strontium and other high-energy metals can cause fire when the moisture in the atmosphere corrodes them. The dehumidifier can control the relative humidity of the mass production area below 1%, so that the lithium battery can be mass-produced and is no longer expensive.

Condensation condensation

When the cold surface is in contact with the moist air, there is condensation on the surface, causing some problems. For example, the outer surface of the display cabinet glass of the supermarket is dewed, and the consumer may not see anything in the cabinet. In addition, the internal structure of the aircraft causes condensation due to the aircraft flying into the humid airspace from the high-cold area, which may have serious consequences. Dehumidifiers have been used to solve these problems. The use of condensation control is not only to solve the problem, such as the low temperature roller in the process, if it is in the dry air environment, it can increase the output and reduce the occurrence of defective products.

  Ice rink

The humid outside air enters the ice rink and the moisture generated by the audience condenses on the surface of the ice, making the ice soft and uneven, which is detrimental to the skater. If the surface temperature of the ice skating rink structure is below the dew point temperature, the surface will also condense, posing a potential hazard to the entire building.

The dehumidifier avoids the above problems, and the freezer can save considerable power by removing the latent heat in advance. The ice surface can also have a good surface for the skater to play.

  swimming pool

A medium-sized swimming pool evaporates about 1 metric ton of water per day. If it is not effectively removed, it will be detrimental to the building structure. In addition, people who are active at the pool will feel uncomfortable. These will affect the income of the pool. The relative humidity should be controlled below 65%.

The swimming pool is a place with high energy consumption, and the running cost is very important. The moisture absorber dehumidifier not only successfully controls humidity, but also saves about 50% in operating costs compared to other systems.

Water treatment plant

The temperature of groundwater and lake water in the cold zone is often lower than the dew point temperature of the atmosphere. Condensation often occurs in the water pipe and control system of the water pipe, causing corrosion and mold growth. The dehumidifier is suitable for use at low temperatures and provides proper humidity control. It also saves the cost of replacing the valve and control system, and also guarantees the quality of the tap water.

Surface treatment and coating

Large cold metal surfaces such as hulls and chemical storage tanks must be painted regularly. Unless the owner can guarantee that the metal surface is dry and clean during application, the manufacturer is not willing to guarantee the surface treatment life. The dehumidifier is used to supply dry air to the surface so that it does not cause condensation, and the contractor can be applied without the influence of weather to shorten the construction period.

  refrigeration

It is well known that the entry of humid air into the refrigerated compartment causes ice and frost on the walls, floors and tubes of the room. Evaporation tube icing can cause headaches such as greatly reduced refrigeration efficiency and elevated refrigeration temperatures.

  The rotary dehumidifier can be operated at low temperatures to remove moisture before it enters the refrigerating compartment, which reduces frosting and improves evaporator efficiency. Dry floors improve operator safety.
