In modern industrial enterprises, many still adhere to their established production line models, reluctant and afraid to try new approaches. They worry that a wrong decision could lead their company to bankruptcy, preferring to remain stagnant rather than risk losing everything. However, the reality is that when others are progressing while you remain stagnant, it is tantamount to gradually marching towards the brink of destruction.

Take compressed air, for instance. As the second-largest power energy source after electricity, it possesses numerous advantageous properties and characteristics that make it a popular choice among many enterprises. Nevertheless, compressed air is not without its flaws. Improperly treated compressed air can inflict significant economic losses on a company.

Compressed air contains a substantial amount of harmful substances, including water vapor, liquid water, oil mist, liquid oil, microorganisms, particulate impurities, rust, and more. Direct application of untreated compressed air can lead to reduced production capacity, degraded equipment functionality, air power losses, increased product defect rates, production equipment failures, shortened equipment lifespans, and so on. Evidently, clean and dry compressed air is of paramount importance.

Among the current methods for treating compressed air, filtration primarily utilizes filters to remove particulate impurities, oil droplets, and some liquid water, providing initial treatment for the compressed air. In traditional filters, the lower end of the filter element is sealed, causing impurities to accumulate inside the filter element. These impurities then permeate through the filter element to the bottom of the filter chamber and are discharged via an automatic drain. However, solid particles cannot penetrate the filter element and adhere to its inner wall, increasing the resistance of the compressed air. Water and oil droplets in the process of permeation may be carried away again by the compressed air.

Refrigeration drying mainly employs a refrigeration dryer to cool high-temperature compressed air, reducing the saturated water content from a high temperature to a low temperature state. Some of the water condenses into liquid water and is discharged via an automatic drain. However, due to its working principle and structural limitations, the refrigerant evaporation temperature cannot drop below 2℃; otherwise, it will freeze and block the pipelines. The heat exchange efficiency and water separation efficiency determine that the actual dew point at the outlet cannot reach the set value of the evaporator. To achieve a lower dew point, it is necessary to increase the power of the refrigerant compressor, which not only raises the procurement cost of the refrigeration dryer but also increases its operating cost. Currently, the measured dew points in most applications range between 20℃ and 35℃, accompanied by a significant amount of liquid water.

Adsorption dryers primarily utilize the water-absorbing properties of adsorbents. Through the principle of pressure swing adsorption, they adsorb moisture from compressed air under high pressure and desorb and regenerate under low pressure, enabling cyclic utilization and obtaining dry compressed air with a general pressure dew point ranging from -20℃ to -70℃. However, the main issues with the currently prevalent dual-tower or combined dual-tower adsorption dryers in China are that the filling of adsorbents is difficult to compact, leading to the formation of tunnel effects that result in substandard performance, high energy consumption, and difficulties in the secondary replacement and filling of adsorbents.

The importance of compressed air is undeniable, yet the current treatment methods are far from ideal. In response to this situation, Beten Technology has successfully developed a mold core adsorption dryer after eight years of technological improvements. Employing the latest mold core adsorption technology and the independent, detachable, and replaceable technology of adsorption modules, it not only enables more compact filling of adsorbents, stable pressure dew point values, and higher safety performance but also facilitates simple and convenient replacement of adsorbents. This can save companies a significant amount of costs associated with equipment repair, maintenance, and production downtime each year.

As the saying goes, "Comparison is the thief of joy." Among the current methods for treating compressed air, these are the main categories. However, upon comparison, it becomes evident that only the Beten mold core dryer can achieve the best results at the lowest cost. This is the drying equipment truly needed in the compressed air purification industry.
