Museum / Archive

Controlling air humidity in the museum is a key factor in preserving great artworks and historical works.
Museums and archives display a large number of cultural relics and history books for future generations, which has strict control standards on indoor air humidity.
Large changes in temperature and ambient humidity can cause ancient books to freeze or crack. Besides, breeding microorganisms can become active through moisture and heat to damage books. Therefore, the indoor temperature and humidity of museums and archives should be kept constant and consistent. In addition, dehumidification can also be used to preserve microfilm to protect the fragile membrane.

Concert Hall

Concert Hall

Displacement ventilation is very suitable way for large spaces to control the indoor humidity. But due to the special return air way of the concert hall, different requirements are put forward for the dehumidifier.
The concert hall belongs to the inner area of the building. The unique double-layer envelope structure is sound insulation and heat preservation. Water vapor content in the air is high. It is easy to produce a large number of bacteria, mold and viruses, which is easy to damage indoor air quality and decorations. So the dehumidifier process is the main problem of the concert hall throughout the year.

Health Effects

Moisture can easily make the floor of the house damp, causing the elderly and children to fall down easily. Wall get moist will be prone to mold and cause the wall peeling. Damp furniture and books will easily become deformed. Wet air tends to keep clothes dry in rainy days. Wet quilt is easy to nourish bacteria. For the family, the humid environment not only affects the household things, but also harms the family health. Especially in the extraordinary period when there are many rainy and rainy days, the trouble caused by humidity is even more worrying.

The effect of humidity on furniture. 
When the relative humidity of the environment is lower than 60%, the items are not easy to get wet. Excessive humidity will cause small water droplets on the floor surface, moldy shedding on the wall surface, home appliances are not sensitive to damp control, wall surface paint discoloration, clothes don't get dry easily. What’s more, severe moisture will breed mildew spots or local volume expansion, which will eventually cause the furniture to deform and crack.
The effect of humidity on air quality. 
When the relative humidity of the environment is lower than 50%, it can prevent the goods from becoming moldy. High humidity can easily breed bacteria and mold. Many people are allergic to mold. The common symptoms include stuffy nose and wheezing when breathing.

Drying Clothes and Purify Air

Drying Clothes and Purify Air

Dehumidification function to dry clothes and purify air.
When the relative humidity is lower than 60%, it is the most comfortable environment for the human body. In the case of continuous rainy days, it is impossible to dry clothes. You can use the dehumidifier in the room at this time. It can help you dry clothes without odor, its dehumidification and heating function can solve the problem of clothes drying on rainy days rapidly. Negative ions have the functions of disinfection and purification, inhibit the proliferation of bacteria, and can help to purify indoor air, give people fresh air as nature.
Industrial Use


 Bridge dehumidification
 Excellent anti-corrosion protection
 Longer durability
 Save resources.

Corrosion damage may cause high cost of bridge construction worldwide. Corrosion of low-carbon steel components and high-strength supporting steel wires can damage the integrity of the structure quickly, leading to safety issues and expensive traffic restrictions, finally the bridge will be closed.

Drying Clothes and Purify Air
Hongtai can protect the cross-corrosion of the girder where the track is located through the dry air circulation of the truss. Compared with the high cost of anti-corrosion coatings and the expensive charge of the bridge maintenance and weight increase, dehumidifier requires minimal maintenance and can save time. At the same time, corrosion protection is also required for corners that are difficult to take care of, so dry air is indeed the preferred method.

Dry Air Storage

Dry Air Storage

Hongtai can be used for dehumidification storage of various materials such as medicine, food, art, electronic equipment and defense equipment.
In contrast, hygroscopic materials will only absorb moisture, which also will become the hotbed of bacteria and mold. The dehumidifier prevents the growth of bacteria and mold by keeping the relative humidity (RH) in the space below 50%. Under controlled humidity, it can prevent storages from condensation and corrosion.
For example:

Corrosive merchandises made of steel and other materials require low humidity. If the relative humidity of the surrounding air is kept below 50%, vehicles, aircraft, equipments and tools will not rust.

Organic materials such as leather and painting contain microorganisms. These will develop into fungi and mold. But if the relative humidity is kept below 70%, that will not happen.

Bacteria need high humidity to survive and reproduce. If the humidity of the surrounding air is kept below 50%, most bacteria will not survive.

Indoor skating rink

In skating rinks and curling rinks, ice must maintain the highest possible quality, while maintaining a pleasant indoor climate. The easiest way to achieve this is to use a dehumidifier to adjust the humidity of the places.

When the door of the ice rink is opened and closed, warm air will enter. Which will form condensation and hang on the ceiling. Condensed water drops dripping onto the surface of the ice rink will cause ice surfaces unevenly. At the same time, if the air is too humid, there is a risk of corrosion damage and mildew, causing damage to the equipment and making people feel uncomfortable. The humidity problem of the ice rink can be solved by installing a dehumidifier to reduce the ambient humidity to the required level.

Remove mold effectively, slow down food deterioration


In the catering industry, the quality of the finished product is very important. In the process of maintaining various high standards, the air humidity in various manufacturing processes must be strictly controlled.
For example:
Dry product

In the production and storage of dry products such as powder soup and broth, if there is no dry environment, these products may stick and deteriorate when mixed or packaged. Dry air can ensure products quality and productivity.
Store cheese to be matured

When storing cheese that is about to mature, keeping the temperature and humidity within tight tolerances is important to ensure the quality and relish of the cheese.

When drying food, if you dry at a lower humidity environment, you can get a higher, more consistent product quality. This also can improve quality and retain more relish. Sometimes the product will be cooled in the cooling stage before packaging. If the air is dried at the same time, it can prevent the product from being humidified again and clogging the conveyor.
Greenhouse plant growers need to be knowledgeable about the specific needs of the plants they are growing and take steps to create a suitable environment for them to thrive.
Temperature: The temperature inside a greenhouse can be difficult to regulate, and it is important to ensure that the plants are not exposed to excessive heat or cold.
Humidity: Depending on the type of plants being grown, humidity levels in the greenhouse may need to be carefully controlled to prevent mold or other plant diseases.
Lighting: Plants require adequate lighting to photosynthesize and grow, so growers may need to supplement natural light with artificial lighting.
Watering and irrigation: Greenhouse plants may require more frequent watering than outdoor plants, and growers will need to ensure that they are using an appropriate irrigation system.
Pest control: In a closed environment like a greenhouse, pests can quickly become a major problem. Growers need to be vigilant about monitoring for pests and take steps to control infestations if they occur.
