Due to the lack of understanding of a switchgear cabinet dehumidifier, you may have a lot of doubts when you use or purchase an electrical dehumidifier for the first time. In order to help you understand the switchgear cabinet dehumidifier more accurately and avoid buying the wrong dehumidifier, there are six common sense about switchgear cabinet dehumidifiers.

1. Which electrical cabinets need a cabinet dehumidifier to control humidity?

An electrical cabinet is a device used to store electrical equipment, usually installed in indoor or outdoor environments. Because electrical equipment is very sensitive to humidity, some specific electrical cabinets require a cabinet dehumidifier for humidity control.

First, indoor electrical cabinets require humidity control. The indoor environment is usually relatively humid, especially during the rainy season or in areas with high humidity. If electrical cabinets are exposed to high humidity, moisture may seep into electrical equipment, causing short circuits, electrical failures, and even equipment damage. Therefore, indoor electrical cabinets need to maintain an appropriate humidity level through humidity control means, such as the use of humidity sensors and cabinet dehumidifiers, to ensure the normal operation and long life of electrical equipment.

Secondly, outdoor electrical cabinets also need humidity control. Although the outdoor environment is not as humid as indoors, the humidity may increase during severe weather conditions such as heavy rain and smog. If the outdoor electrical cabinet does not have humidity control measures, rain or moisture may seep into the equipment and cause electrical failures. Therefore, the electrical cabinets installed outdoors are usually also equipped with humidity sensors or electrical cabinet dehumidifiers to ensure the normal operation of the equipment in bad weather.

2. Where is the best location to install the switch cabinet dehumidifier?

The switchgear cabinet dehumidifier is best installed close to the switchgear so that it can effectively remove moisture. In industry, switchgear is often subject to high humidity or damp environments, which can lead to malfunction and damage to equipment. Therefore, it is very important to control the humidity by installing an electrical dehumidifier.

The choice of installation location should take into account the following points:

Close to the switchgear: The switchgear cabinet dehumidifier should be located as close as possible to the switchgear so that it can quickly absorb moisture and reduce humidity. This helps protect equipment inside the switchgear and avoid electrical problems caused by moisture.

Efficient air circulation: When choosing a location to install a cabinet dehumidifier, you need to ensure that it will provide sufficient air circulation to absorb and release moisture outside. Try to avoid installing electrical dehumidifiers in crowded spaces or where they are blocked by obstacles.

Safety considerations: The cabinet dehumidifier should avoid direct contact with water sources or environments with explosion hazards. Make sure that the surrounding environment of the installation location is dry and safe.

In short, the best installation position of the electrical cabinet dehumidifier is close to the switchgear, and installed under conditions that can provide sufficient air circulation and safety guarantee. This can effectively control the humidity and protect the normal operation of the equipment.

3. Why can the switch cabinet dehumidifier pump out water?

The switch cabinet dehumidifier converts the moisture in the humid air into liquid water through the principle of evaporation and condensation and discharges it. In the industrial field, switchgear is often exposed to harsh environmental conditions, such as high temperature, high humidity, corrosion, etc., which will cause moisture to accumulate inside the switchgear. The accumulation of moisture will dampen and corrode the electrical components inside the switchgear, affect the normal operation of the equipment, and even cause dangers such as short circuits and fire. Therefore, the role of the switchgear cabinet dehumidifier is particularly important.

The working principle of the switchgear cabinet dehumidifier is realized by the built-in evaporator and condenser. First, cabinet dehumidifiers draw moist air inside. Then, through the evaporator inside, the moisture in the humid air condenses into beads on the cold surface. Then, the condensed water droplets will be introduced into the condenser, and the water droplets will be converted into liquid water by cooling. Finally, the cabinet dehumidifier drives the liquid water out of the switchgear.

The reason why a switchgear cabinet dehumidifier can pump out water is that it can effectively control the humidity inside the switchgear. When the moisture is sucked by the dehumidifier, the humidity will gradually drop until it reaches the set humidity range. At this time, the moisture in the humid air will condense into water droplets under the action of the electrical cabinet dehumidifier and be discharged from the switchgear. Through the work of the cabinet dehumidifier, the humidity inside the switchgear is effectively controlled to ensure the safe operation of the equipment.

4. Does the switch cabinet dehumidifier have any requirements for the environment?

The switch cabinet dehumidifier has certain requirements for the environment when it is used in the industrial field. First, the temperature of the working environment should be within an appropriate range, usually between 5°C and 40°C. Temperatures that are too low or too high can affect the performance and effectiveness of the cabinet dehumidifier. Secondly, the humidity of the working environment of the cabinet dehumidifier also needs to be controlled within a certain range, usually 30% to 90% relative humidity. Humidity that is too low can prevent the dehumidifier from functioning properly, while humidity that is too high can reduce the efficiency of the dehumidifier. In addition, the air quality around the dehumidifier also needs to be paid attention to, avoiding an environment with a lot of dust, chemicals, or corrosive gases. Finally, the location of the industrial dehumidifier also needs to be considered. Choose a dry, ventilated area away from excessive humidity or direct sunlight. All in all, in order to ensure the normal operation and effectiveness of the switch cabinet dehumidifier, the temperature, humidity, and air quality of the working environment need to meet certain requirements.

5. What is the dehumidification capacity of the cabinet dehumidifier?

The dehumidification capacity of the cabinet dehumidifier refers to the amount of moisture that the dehumidification equipment removes from the air per unit of time. In the industrial field, the electrical dehumidifier is widely used to control the humidity of the environment to meet the humidity requirements in the production process.

The dehumidification equipment converts the moisture in the air into liquid by hygroscopic method and discharges it through the drainage pipe. The amount of dehumidification depends on the performance of the equipment and the difference in humidity. Common industrial dehumidifier includes condensation dehumidifiers, adsorption dehumidifiers, and membrane dehumidifiers.

In the industrial production process, the control of humidity is very important for product quality and production efficiency. High humidity environment can easily lead to moisture, corrosion, and deterioration of the product, affecting the quality and service life of the product. At the same time, high humidity can easily lead to equipment failure and safety hazards. Therefore, controlling the ambient humidity through a cabinet dehumidifier can ensure the smooth progress of the production process.

The amount of dehumidification needs to be determined according to the specific industrial environment requirements. Different processes and products have different requirements for humidity, so the selection and configuration of cabinet dehumidifiers will also be different. When selecting cabinet dehumidifiers, factors such as working conditions, humidity range, dehumidification effect, and energy consumption need to be considered.
