Heatless Desiccant Compressed Air Dryers

Feature & Benefit

1. The non-thermal regeneration adsorption dryer is a kind of dehumidification and purification device that uses the non-thermal regeneration method (no external heat source) to adsorb and dry compressed air based on the principle of pressure swing adsorption.

2. The heat-free regeneration adsorption dryer (hereinafter referred to as the heat-free suction dryer) is carefully designed and developed by our company in recent years on the basis of digesting and absorbing advanced technology of similar foreign products and considering the actual situation of domestic users. High-quality models. Under normal operating conditions, the dew point (under pressure) of the air can be reduced to below -40℃, and the lowest can reach -70℃. It can provide oil-free and water-free high-quality compressed air for a few applications that have high requirements for air quality. It is especially suitable for use in cold areas in the north and other places where the ambient temperature is below 0°C.

3. The heatless absorption dryer adopts a double tower structure. One tower absorbs moisture in the air under a certain pressure, and the other tower uses a small portion of dry air slightly higher than atmospheric pressure to regenerate the desiccant in the adsorption tower after a certain period of time, The two towers are switched to ensure continuous supply of dry compressed air.

4. Unique computer control system, visually display the running status of the dryer, and has multiple alarms, protection functions and DCS remote control interface to ensure trouble-free use.

5. The actuator adopts pneumatic angle seat valve and pneumatic butterfly valve. The pneumatic control system adopts deep dry air source and then filtered to ensure reliable action and avoid valve leakage.

6. The height and diameter of the adsorption tower are accurately calculated and experimental results, and the important parameters such as flow velocity and heat and mass transfer are indeed mastered, so as to avoid excessive wear of the adsorbent and tunnel effect.

7. Professional program control design, small air pulse and air pressure fluctuation, effectively reduce the outlet air dust and the regeneration air noise.

8. Convenient and practical cycle time mode and energy-saving economic mode. Regenerative air volume and time program can be adjusted to adapt to various actual use conditions and outlet dew point requirements.

9. The support base is stable and beautiful in appearance, easy to install, use and maintain.
