Dehumidifier for the compressor - type and working principle

Where applicable compressor dehumidifier

Dehumidifier - a piece of prime necessity for the compressors, which are the components of the complex mechanism of pneumatic tools. It is imperative that such devices are fed in perfect clean air without dust or fine particle fraction.

With the stated construction manages to remove excess moisture particles which are formed by condensing water vapor. The droplets of liquid appear at the receiver as well as inside the air system. Such a phenomenon occurs when too intense compression of the air. In addition, compressed air can also have oil particles. Their appearance is associated with the use of piston compressors which are used to lubricate the fat-like consistency.

Without having to install the drainage mechanism with air system may have some problems. Therefore establish such mechanisms with the following objectives:

• preventing the pressure drop in the system;
• rust prevention;
• removal of harmful micro-organisms;
• exception pneumatic output substation failure.

Furthermore, by means of dehumidifiers perform regular cleaning in boiler heating systems.

What problems is the lack of desiccant

In case of contact with the air outside the closed system of particles, serious damage may occur in the equipment. Consider what you might encounter if we neglect mounting drier.

1. Mixing fat and moisture leads to the formation of a thick emulsion which seals the channels and grooves.
2. If the system operates under conditions of low temperature, moisture inside zamerznot, resulting in deformation of the structure.
3. The presence of condensate in the air system does not allow for its use in the pharmaceutical, chemical purposes, and also for the food industry.
4. When humidity within the air system is the formation of rust, which eventually will turn overlapped channels.
5. Moisture in atomizers inadmissible, both because this will not be possible quality painting of automobiles, as well as other facade surfaces.

Design and operation of the dryer, depending on the type of

To clean the air of excess moisture are used as modular, and single system. They are, according to the principle of operation and design vary by species.

refrigeration systems

The refrigerated device uses two circuits. In the first moving cooled air, and the second refrigerant. All the moisture is removed at the same rate of flow of hot and cold have been passed through the two systems, "air-to-air" and "air-refrigerant". In the evaporator, moisture in the dropping dew microparticles, passes the condenser. Thence transported to the capillary tube. After passing through mechanisms humidity rate is 5 g / m, while the temperature of a dew point of + 3 ° C.

absorption device

Adaptations adsorption type operate on the basis of silica gel, which is used in various industries. This design is worth several times more expensive than the previous one. It is the most effective drainage system. The composition, which is filled, change every five years. The device works even in cold environments without disruption. Experts point out that for such adaptations to the sorbent would require additional filters.

membrane structures

The device is a small-size housing, taken wherein several membranes, is a fiber. They stably retain, moisture contained in the air and oils. No moving parts design makes it possible to operate the device for a few years longer than previous versions. The design differs quick installation and is capable of operating at a temperature -70ºS. However, if in the room where the used compressors, the air is too polluted, these devices are not recommended for use.

Pros and cons of using dehumidifiers

There is equipment that can be used without integrated dryer. Nevertheless, dryer design is very important. This applies particularly acute chemical, petrochemical and engineering industries. Consider what advantages can be extracted from the application of this type of auxiliary equipment:

As for the drawbacks, they emit only three:

Often, the standard compressor devices have built-in separators, which have dry air property by 80%. However, if there is a need to use the maximum flows dried, then come to the aid dehumidifier.

How to choose the design that does not make mistakes

If you, as the owner of the house, completely nothing about plants such as dehumidifiers, are best left to the right professional choice. It will help to more accurately determine the type of structure that is required. Be prepared to tell him about the conditions under which will be operated by the mechanism.

According to the conditions of use

This is a very important criterion for selecting the desired unit. For example, for use in an automobile shop in which regular paint coating of bodies and other parts and machinery suitable absorption type. It is best to absorb moisture and will last a maximum of time without maintenance.

With respect to mechanisms such as the refrigerator, they are best suited for industrial purposes in the chemical plants, where not only the moisture and oil may be present in the air, but also chemical connection. A membrane structure ideal for home use, such as after manual washing machine as road dryer.

Specifications

When using pneumatic equipment, whatever the purpose, it is necessary dehumidifiers whose work will conform to the standards GOST and ISO 8573-1. Consider what exactly the parameters to be followed:

• 1.4.1 Class moisture, dew point temperature of not more than 3 ° C;
• pressure range should be within from 3 to 7 bar;
• inlet air temperature to 35 ° C.

It is advisable to choose a device that can operate with small temperature margin. For example, in a hot instrument must operate smoothly at a temperature of + 50 ° C.

Bandwidth

With regard to the capacity of devices, the different conditions it varies. Considered the most optimal range 5,2-8 m³ / min. Such characteristics would be sufficient to use the same device in the home and for industrial purposes.

Leading manufacturers of dehumidifiers

Both industrial and domestic dehumidifiers are used quite widely, so you should know which specific brands opt professionals. Consider the most common brands of devices.

1. MARK. A well-known manufacturer that gives the customer high quality products. Brand is specialized in all kinds of dehumidifiers. All of them are characterized by durability and practicality.
2. KRAFTMANN. The German company, is a leading in the industrial market. It produces only the absorption and refrigeration compressors dryers. It produces several series with a modified control type.
3. EKOMAK. Compressed air dryers, which are divided into devices by series of hot and cold regeneration. Such devices are well suited for use in workshops and factories.

The best models of dehumidifiers for compressors

Since all compressors are afraid moisture, they just need a good oil and water separator. If you do not have large financial resources, you can purchase models easier. However, their quality is quite decent level.

Typically, the compressors can be used not only in the production of some technical work, but also to be present in almost every household appliances and cars. Therefore, the dryer - this is quite an important part. The unit must be provided in any type of modern technology, as it affects the security and durability of many mechanisms.
