Technical Advantages of Our Heated Regenerative Desiccant Air Dryer
(1) More Energy Efficient
Micro heat desiccant air dryer has an electric heater. It can take advantage of some ambient air. 所以, the regeneration air consumption is much lower in a heatless dryer. 以下, we will compare the operating costs of the two dryers.

總結, the micro heat dryer is more energy-efficient than the heatless dryer. Assume that the flow rate of the dryer is 6.5m³/min. The former saves CNY19794/year than the latter.
(2) Reliable And Stable Dew Point Guarantee
Our desiccant air dryer system uses a long airflow channel design. Not only does it reduce noise, but it also has an extremely low dew point. 而且, our heated desiccant air dryer is filled with enough adsorbents. So its drying effect is perfect. 此外, this heated desiccant air dryer has an electric heater. There is a thermostatic controller. It can keep the regeneration air temperature constant. 所以, prevent the sorbent from overheating.
Another structure advantage is airflow distribution. There are diffuser devices at the bottom of the adsorption towers. This allows the adsorbent to absorb the water fully. Airflow is slow. It also reduces the pressure loss. 同時, it can reduce the wear on the desiccant beads. 所以, our adsorption air dryer can reach a low dew point. 除了, the dew point curve can remain smooth.
(3) Quality Dryer Spare Parts
We use the AirTAC brand two-position five-way solenoid valves. 這樣, control the switching of the pneumatic valves. Electrical components are also well-known brands. To ensure the reliable operation of the dryer.
How Does Micro Heated Regenerative Desiccant Air Dryer Work
It uses the PSA + TSA working principle. At high pressure and low temperature, the adsorbent has adsorption properties. In turn, it has desorption properties at low pressure and high temperature. This increases the adsorption capacity of the desiccant beads per unit weight. 所以, it realizes deep drying of compressed air. Micro heat desiccant air dryer system includes the working processes:
(1) Adsorption And Drying Process
Compressed air passes the drying tower (e.g., tower A). Aluminum oxide and molecular sieves absorb large amounts of water vapor. This adsorption process continues until Tower B is completed regeneration.
(2) Regeneration / Desorption Process
The dryer desorption process includes six steps. 首先, the regeneration tower (e.g., tower B) reduces pressure to atmospheric pressure. 第二, it starts the hot purge process. It will consume about 3~8% compressed air. And an electric heater will heat the air. So it can remove the water in the regeneration tower. 第三, the cold purge process begins. It also uses 3~8% compressed air as regeneration air. They can cool down the temperature of desiccant beads.
The A/B tower constantly switches workflows. 最後, the compressed air enables deep drying. Above is the working principle of a heated desiccant air dryer system.
