Treating air is necessary for many standard and non-standard processes, whether in manufacturing or other industries. Part of the practice is humidity control, which is essential for moisture and can negatively impact building materials. Not only that, it can have a massive negative effect on the comfort of the occupants of the building.
A more severe impact that improper humidity control may have is to derail workers’ performance in a facility where hygroscopic materials are handled. It goes to say that humidity is one of the critical aspects of a building that many overlooks. It affects people’s health, comfort, performance, and building.
It is no wonder commercial dehumidifiers are an essential part of buildings and factories’ operational systems. An industrial dehumidifier is there to extract the particles of water in the ambient air, thus preventing condensation. Such equipment is essential for businesses, saving them from costly machine repairs, interior maintenance, or furniture replacement.
At the same time, dehumidifiers help workers have much better working conditions. However, that is not to say that the process involved doesn’t face any difficulties. Fortunately, the technologies used for the dehumidification process significantly improved in the last few years. Today, controlling indoor humidity has become much more manageable.

Basic Dehumidification Methods
There are three basic methods of dehumidification. They are heating and ventilation, adsorption, and condensation. The dehumidifying process involves the unit reducing the steam contents, water particles, or moisture contained in the air. It seems like a simple process, but there are several ways how it is done. They are:
Heating and Ventilation Method
The heating-and-ventilation method involves increasing a room’s air temperature, followed by intense ventilation applied. It is not as efficient as other methods since its possibility of use and effectiveness depend on external conditions. This method achieves the best results during winter.
The method is most effective when the dehumidified room has a higher temperature while the external environment has a lower temperature. Thus, it is not ideally applied during spring and autumn, much more so during summer. Dehumidifying humid walls with this method is tricky, while using gas heaters is not ideal.
Another critical consideration in deciding to use this method is the high costs connected to it. This method is expensive, mainly because dehumidifying takes a long time. Also, achieving the best results is only possible at the highest temperatures. Thus, it is going to need plenty of heating power.

The adsorption method is as it sounds – the hygroscopic materials remove humidity from air by adsorbing it. The application of this method employs adsorptive dehumidifiers. They are devices constructed with rotors, often made with properly profiled aluminum sheets. With that, the rotor has axial capillaries with a hygroscopic-covered surface.
It results in the dehumidifier having a large humidity-absorbing area. An electric motor by a (usually) belt-type transmission drives the rotor. The air is dehumidified behind the rotor, called the dehumidifying sector. Another section of the device is the regeneration sector, where the hot air flows and is sent outside.
One of the good qualities of this dehumidifier is its rotor is washable, highly durable, and can even self-clean. Thus, there is little chance of bacteria developing. Moreover, absorption dehumidification allows for dehumidifying air at sub-zero temperatures and even without cooling. Therefore, it is widely used in the food and pharmaceutical industries.
This method removes humidity using a condensation air dehumidifier, which cools moisture in the air, and causes an out-dropping of humidity. The dehumidifier consists of an extractor fan, heat exchangers, compressor, and expanding element. With the extractor fan, humid air is forced out through the heat exchangers.
Because the evaporator temperature is below the dew point temperature, the steam condenses. These condensates gather on the walls of the dehumidifier tank, which are often removed through the sewage system. The air passes through the evaporator, which cools and dries it, then is heated again when it flows through the condenser.
The dry air returns to where it came from, thus effectively improving the humidity in that room. Just like the heating-and-ventilation method, a few things affect the efficiency of this method. Specifically, they are the type of machines used and operating conditions. Still, it is more economical and practical than other dehumidification ways.
Emerging Trends on Dehumidification
The market outlook for the global dehumidifiers market is said to have a projected growth rate of 7.3% from this year to 2023. More and more consumers show an increased inclination towards having better air quality at home, thus fueling the significant growth of the market.
Dehumidifiers used to be crucial devices in commercial and industrial facilities. Today, it has also been an essential appliance in residential buildings for maintaining a specific moisture level. It plays a vital role in controlling moisture content in food packaging and many other industries, given the ever-changing weather and seasons.
