What is Heated Desiccant Air Dryer
It is a twin tower desiccant type air dryer. It is not only a pressure swing adsorption dryer but also a temperature swing adsorption dryer. Different from a heatless air dryer, there is a heater. It adopts the micro heating regeneration method. Then absorb and dry the compressed air. Therefore, it reduces the regeneration air loss.
Why Choose Our Heated Desiccant Air Dryer
(1) Low Energy Consumption
Compared to a heatless air dryer, the air loss is much lower. The air loss of our heat desiccant type dryer is 6%. There is an independent electric heater. It improves the shortcomings of heatless regenerative dryers. That is large regeneration air consumption, short switching cycle, and high failure rate. The energy saving rate can reach more than 40%. So it makes the operation costs lower.
In addition, it also uses a thermostatic controller. Keep the regeneration air temperature constant. Then, avoid the adsorbent from overheating.
(2) Reliable Dew Point
Firstly, our adsorption air dryer adopts a long process design. So, it can guarantee an extremely low dew point. Secondly, there are diffusers at the bottom of the adsorption tower. It ensures enough contact time between compressed air and adsorbent. Without this device, there would be “dead spots” for adsorption.
In addition, it can reduce the impact of air current on the desiccant beads. Thus, it guarantees the service life. Thirdly, our adsorbent filling is sufficient. So the dew point of our dryer is low and stable. Our dryer uses microcomputer intelligent automatic control. The air supply is continuous and stable. Intermittent air cuts will not occur. Easier to handle. Therefore, the dew point fluctuation is very small.
(3) High Quality Raw Materials And Spare Parts
Our desiccant type air dryer uses two kinds of adsorbents. Namely high-efficiency activated alumina and molecular sieves. The desiccant has a long service life.
In addition, our dryer adopts a wear-resistant pneumatic butterfly valve. Reliable performance and long life. The two-position, five-way solenoid valve is also a well-known brand. So it ensures reliable operation of absorption type dryer.
(4) Strong Customization Ability
If needed, we can add a SUTO dew point meter. In this way, it can achieve TSE dew point energy-saving control. Besides, a variety of control methods are available. That is, interlocking control, remote communication, and IoT control. They can adapt to different requirements.
In addition, we can customize lower dew points. It can reach -70℃. Moreover, we can also produce high-pressure adsorption air dryers. Max pressure is up to 100 bar.
(5) Work With World Famous Air Compressor Brands
Lingyu is a famous desiccant type air dryer brand in China. Moreover, our absorption type dryer usually works with famous compressor brands, such as Atlas Copco, Ingersoll Rand, Kobelco, Hitachi, etc.
Pressure Swing Adsorption Dryer vs Temperature Swing Adsorption Dryer
(1) Pressure Swing Adsorption
PSA has wide application in the drying of gases. Adsorb at higher pressure. Desorb under reduced pressure. This is called pressure swing adsorption.
Generally carry out desorption at atmospheric pressure. It has little desorption effect if it adsorbs moisture under high pressure and reduces to atmospheric pressure. After depressurization, must purge regeneration air with low relative humidity. In this way, the desorption can be completely desorbed. Then, this is the PSA process of adsorption air dryer.
(2) Temperature Swing Adsorption
TSA refers to adsorption at lower temperatures. Then, desorb at a higher temperature. This is another principle of desiccant type air dryers. Because the adsorption capacity will decrease with temperature increasing. During regeneration, the regeneration gas is purged to increase the temperature. So it will reduce the relative humidity.
FAQs
Generally, we need to replace the adsorbent about two years. Of course, it also depends on the use time of your dryer. In addition, different usage environments have different replacement cycles.
In general, installing a refrigerant air dryer is necessary. If there is a refrigeration dryer, the drying effect will be better. Of course, it also depends on three points. That is, dew point, inlet air temperature, and ambient temperature.
If the two temperatures are not high, and the dew point is -20°C or -40°C, then it is okay not to use a refrigerated dryer. For example, it is common not to install refrigerated dryers in Russia. But now, if the dew point is -70°C, there must be a refrigerant dryer.
Aside from the adsorbent, the muffler is the most frequently replaced. So you can buy the silencer muffler and the adsorption desiccant type air dryer.
