Adsorption dryer
Adsorption-type air dryers are widely used in industrial fields as air drying equipment. They effectively remove moisture from compressed air through the physical adsorption action of adsorbents, providing dry and clean air for various production processes.

Operating Principle
The core principle of the adsorption dryer is to utilize the adsorption properties of adsorbents (such as activated alumina, silica gel, or molecular sieves) for water absorption. When humid compressed air enters the adsorption tower, the water is absorbed by the adsorbent, thereby achieving air drying. When the adsorbent approaches saturation, it is switched to the regeneration tower, where water is desorbed using reduced pressure or heating to restore the adsorption capacity. This dual-tower switching design ensures that the equipment can continuously and stably output dry air.
• Deep drying capability: It can reduce the dew point temperature of compressed air to an extremely low level, even below -40℃, meeting the extremely high requirements for air humidity in certain processes.
• High stability: It is insensitive to changes in the flow and pressure of compressed air, and can maintain a stable drying effect under different working conditions.
• Energy-saving and environmentally friendly: The non-thermal regeneration type equipment only requires the control of valves by an electric control box to switch, resulting in extremely low energy consumption; the micro-thermal regeneration type equipment further reduces energy consumption by optimizing the heating process.
• Simple maintenance: The equipment has a simple structure, a low failure rate, and low maintenance costs. The main maintenance tasks include regular replacement of the adsorbent and cleaning of the filter.
- Adsorption Tower: As the core component of the equipment, it usually adopts a dual-tower structure. One tower is used for adsorption, and the other tower is used for regeneration. The alternate operation is achieved through valve switching.
- Adsorbent: It is the key material for achieving drying. Commonly used adsorbents include activated alumina, silica gel, and molecular sieves, etc. They have different adsorption characteristics and application scenarios. Users can choose the appropriate adsorbent according to actual needs.
- Control System: It includes a controller, sensors, and display screens. It is used to monitor the operating status of the equipment, automatically control the adsorption and regeneration processes, and ensure the stable operation of the equipment.
- Directional Valve: It is used to control the flow of compressed air, enabling the switching between adsorption towers and ensuring the continuous operation of the equipment.
- Filter: It is installed at the inlet and is used to remove impurities and oil stains from the compressed air, protecting the performance and service life of the adsorbent.
Regularly replace the adsorbent: The lifespan of the adsorbent is limited. It needs to be replaced regularly according to the usage situation.
Clean the filter: Regularly clean the intake filter to prevent impurities from blocking it and affecting the performance of the equipment.
Check the valves and control system: Regularly inspect the sealing performance of the valves and the accuracy of the control system to promptly identify and solve problems.
Record operation data: By recording the operation data of the equipment, abnormal situations can be detected in time and maintenance can be carried out in advance.
