An industrial dehumidifier is a device that removes excess moisture from the air in large volumes. Widely used in various sectors of the national economy.
There are many different factors to consider when choosing an industrial dehumidifier:
- air exchange;
- incoming air flow pressure;
- inlet and ambient temperature;
- dew point indicator.
Additionally, it is necessary to take into account the pressure loss of the air flow in the dehumidifier itself, its filter, and a number of other features (the volume of the room, the number of people working in it, etc.).
When choosing an industrial dehumidifier, its reliability, ease of operation and the cost of future maintenance are taken into account.
Equally important is the power consumption of the device. The higher the performance, the more energy is consumed. Here it is important to find the “golden” middle ground — to provide the desired air humidity at minimal cost.
As you can see, the process of choosing an industrial dehumidifier is quite complicated, and only professionals in their field can solve it. By the way, there are such specialists in our company. They are always ready to give advice at a high professional level. Contact.
What are the types of industrial dehumidifiers
A wide range of industrial dehumidifiers is represented by various types. The main difference is in the principle of operation. The most common are devices of condensation and adsorption types. Less commonly used:
- refrigeration (or refrigeration);
Condensation dryers work on the principle of moisture condensation. The temperature difference in the heat exchangers is obtained by compressing the refrigerant with a compressor.
Application in a wide range — industrial premises, warehouses, museums, pharmaceuticals, food industry and other areas where increased requirements are imposed on the moisture content in the air.
Adsorption dryers use the principle of extracting moisture from the air with an adsorbent, for example, silica gel.
Dehumidifiers of this type are widely used in explosive and flammable production.
Refrigeration (refrigeration) dryers in principle, their work is similar to a conventional refrigeration unit. Do not require large investments in operation and maintenance. The disadvantage is that they have a low dew point.
Membrane and deliquiscent devices have a narrow scope. They work without external power sources, the decrease in humidity is insignificant.
A careful study of the characteristics of various types of air dryers will allow you to correctly determine the type of device you need. But at the same time, the word of experts should be final.
Note. Incorrect selection of dryer type can lead to production stoppage.
How a duct dehumidifier works
The duct dehumidifier works on the principle of condensing the moisture contained in the air and then removing it. At the same time, it heats the air leaving the room.
The work process is carried out as follows. The refrigerant compressed by the compressor (in most cases freon) passes into a liquid state. It heats up to a high temperature.
In a liquid state, it enters a hot heat exchanger, where it partially gives up its temperature. Further, passing through the capillary tube, the refrigerant turns into a gas. The process is accompanied by strong cooling. Cold gas enters the next heat exchanger, significantly lowering its temperature. The next “station” of the refrigerant is the compressor. The closed cycle is repeated.
At the same time, moist air passes through the cold heat exchanger. As a result, the moisture contained in it condenses on the walls of the evaporator and flows into a special moisture-collecting container or drainage pipe.
Cooled, but already dry air is driven by a fan through a hot heat exchanger, where it takes its heat and then enters the room.
This removes excess moisture from the air and warms it up.

Thus, industrial dehumidifiers differ from household dehumidifiers in performance, increased size and weight.
