Frozen compressed air dryer: an essential choice for industrial production

Posted on 2024-12-01

Influence of air humidity in industrial production

In many industrial production processes, the quality of compressed air is very important. However, compressed air with high humidity can cause pipeline corrosion, machine rust, and even affect the quality of the finished product. For example, in the spraying operation, too much water vapor may cause the coating blistering or peeling; and in the precision electronic assembly line, it may cause the circuit board short circuit. Therefore, taking effective measures to control the moisture content in compressed air is of great significance for protecting equipment and improving production efficiency.

Working principle of refrigerated compressed air dryer

The refrigerated compressed air dryer uses a refrigerant circulation system to cool the incoming humid air below the condensation point, so that the moisture in it is condensed into liquid water droplets, and then discharged through a separation device. After this process, the dry and low-temperature air is heated again to close to the intake air temperature, thereby preventing the occurrence of the condensation phenomenon. This drying method can not only greatly reduce the relative humidity of the air, but also effectively avoid the shortcomings of the traditional adsorption dryer regeneration gas consumption.

Reasons for choosing a refrigerated compressed air dryer

Compared with other types of drying equipment, refrigerated compressed air dryers have obvious advantages. Firstly, the energy consumption is lower, and the operating cost is more economical; secondly, it occupies a small area and is easy to install in the existing production line without occupying too much space; secondly, the maintenance is simple and convenient, and the daily inspection and maintenance workload is not large. It is very suitable for continuous operation of the industrial environment. Most importantly, it has good stability and can continuously provide a stable supply of dry gas under various harsh conditions.

Interpretation of key performance indicators

When choosing a refrigerated compressed air dryer, there are several core indicators worthy of attention. The first is the dew point temperature , that is, the temperature at which the remaining water vapor in the treated air reaches saturation and begins to condense. Generally, the lower the better, indicating that the higher the degree of drying. The second is treatment air volume , which refers to the maximum air flow that the dryer can handle per unit time. It is necessary to select products of appropriate specifications according to actual needs. In addition, there are pressure loss, energy efficiency ratio and other factors also need to be considered.

Actual Case Sharing

A well-known automobile manufacturer has solved the problem of clogging the paint spray gun that has plagued the workshop for a long time after the introduction of a refrigerated compressed air dryer. Because the air contains more water, the viscosity of the paint is unstable, which seriously affects the quality and efficiency of the coating. Since the use of high-performance refrigerated dryers, it has not only completely eliminated this hidden danger, but also greatly increased the overall production capacity of the production line. Similar success stories have been widely reported in various fields such as pharmaceuticals and food processing.

Installation and Maintenance Guide

In order to ensure the best performance of the refrigerated compressed air dryer, the correct installation and regular maintenance can not be ignored. First of all, the choice of installation location should be away from heat sources and flammable substances to ensure good ventilation conditions. Pay attention to the sealing when connecting the pipeline to avoid unnecessary energy waste caused by leakage. Regarding maintenance, it is recommended to clean the filter at least once a quarter, conduct a comprehensive inspection every year, and replace aging or damaged parts in time.

Future directions

With the advancement of science and technology and the increasing awareness of energy conservation and environmental protection in society, refrigerated compressed air dryers are also evolving. Future products will pay more attention to the improvement of energy efficiency ratio, using new environmentally friendly refrigerants instead of traditional Freon to reduce the greenhouse effect. At the same time, the addition of intelligent control system will also make its operation easier and faster, and meet more personalized needs.

Buying Guide

Before deciding to purchase refrigerated compressed air dryers, companies should clarify their actual needs, such as the amount of air to be processed, the minimum dew point temperature expected to be achieved, etc. In addition, we also need to pay attention to the service system of suppliers, including pre-sales consultation, technical support and after-sales guarantee. Choosing well-known brands and experienced manufacturers to cooperate can largely avoid potential risks and ensure the smooth implementation of the project.
