In households, air dryers are commonly used to regulate microclimate parameters. The opposite of this technique is a humidifier, which increases the moisture content of the air. In production and in the construction industry, this equipment has several other tasks. Most often, an industrial air dryer is used as an integral part of a pneumatic infrastructure. The unit also removes excess moisture, but only in compressed air, which is thus prepared for supply to the compressor.
How does an industrial dryer work?
In industry, the most common installations that use a refrigerant as an active medium. The basis of the functional system is the heat exchanger. The air streams entering the device are first cooled, after which condensate drops out. Otherwise, the principle of operation of the air dryer is similar to refrigeration equipment. The formed moisture is discharged through a drainage tube into a special reservoir. In this case, there may be different design versions of the storage part from the point of view of the device of the collection tank. It is most rational to organize a drain directly into the sewer, but there is no such possibility.at every plant.
In turn, the cooled air is also separated from moisture and sent to the second, warm heat exchanger, where heating takes place. As a result, the air dryer for the compressor generates an optimal environment, ready for further use in the pneumatic system.
Main criteria for choosing a dryer
Two characteristics of such units are fundamentally important - power and performance. The power potential of the equipment varies between 330-2000 watts. The selection of the unit according to this indicator entirely depends on the capacities of a particular enterprise. But keep in mind that most modern industrial-type dehumidifiers are powered by a 380 V mains.
No less important are performance indicators. This setting determines how much fluid the compressor air dryer will provide per minute. On average, the productivity is from 1,000 to 20,000 l/min. In choosing equipment for this value, it is worth relying on the area of \u200b\u200bthe room. The larger it is, the more efficient the dehumidifier should be in terms of generating air volumes.
Types of dehumidifiers
As a rule, there are two types of such units. The first and most popular type of industrial dehumidifiers are the mentioned models with a refrigeration principle of operation. Absorption plants are less common, but they can still be effective in some operating conditions. Their main feature is the absence of a channel that removes moisture. Whereas in a traditional design, an industrial dehumidifier collects condensate in a special container or directly drains it into the sewer, absorption modifications literally absorb moisture.
For this function, a filler is provided in the equipment device, to which the concentrated moisture is directed. S alt absorbing agents and self-healing elements like zeolite or silica gel are used as this substance.
Manufacturer Reviews
The segment is quite narrow, so the choice of manufacturers is modest. The greatest interest on the part of professionals is the equipment of Ekomak and Fiac companies. Models of the first brand show themselves well precisely in working with compressor stations. Ekomak for the most part offers refrigerator-type designs, so experienced users recommend that you first think over moisture removal systems. In general, this brand's industrial dehumidifier performs well at medium power, ensuring the stability of the main function.
Fiac's models evoke positive impressions thanks to the combination of high performance and ergonomics. In particular, the units of this brand are distinguished by their ease of operation and low maintenance requirements. Most importantly, some modifications are equipped with an effective sound insulation system, so they can be used inlaboratories, administrative buildings, etc.
What else to consider when choosing?
Through special calculations, you can make the best choice of dryer, suitable for specific application requirements. But, as practice shows, in the course of operation, new requests for equipment characteristics may also arise. In particular, work in conditions of high humidity adversely affects the condition of the surfaces of many units. As a result, already after months of use, maintenance personnel repair dehumidifiers that have been corroded. Therefore, you should initially refer to those models that have a moisture-proof coating on the case.
Also, experienced users recommend not saving on automation and control systems. Modern models of dehumidifiers are increasingly receiving the option of visual control of air pressure, and are also provided with automatic liquid drainage systems. This option allows you to rationally use the resource of the equipment, reducing the cost of energy supply.
Conclusion
The need to equip industrial facilities with air dryers cannot be underestimated. The reliability of pneumatic networks depends on the quality of operation of such systems, which often fail precisely because of the consumption of air with unsatisfactory characteristics. In addition, an industrial dehumidifier is required for other purposes. Its function is also used for its intended purpose - for example, to create an optimal microclimate in a large room orgetting rid of excess moisture from building materials. At the same time, for each task, a dryer suitable for technical and design parameters should be selected.
