(2) TSE Dew Point Energy Saving Control Function
TSE uses the actual outlet dew point for dynamic control. It detects the saturation of the in-line tower in real-time. If it does not reach saturation, it will extend the adsorption cycle. This ensures a stable dry dew point. Dahası, it maximizes energy savings in regeneration. It can save more than 30% compared to a desiccant dryer system without TSE.

How Does Zero Air Loss Desiccant Dryer Works
Regenerative air dryer adopts advanced chemical technology. It uses desiccant beads to absorb water vapor in compressed air. Good adsorbents have porosity. Ayrıca, they have a large specific surface area.
Under pressurized airflow, the adsorbent surface has the property of adsorbing water vapor. Aksine, under the reduced airflow, the water vapor will fall off. back into the airflow. Aynı zamanda, heating helps the water vapor overcome the Van Der Waals force. Thereby desorb the adsorbent.
The specific workflow of a regenerative desiccant air dryer is as follows:
(1) Adsorption Drying Process of The Desiccant Dryer System
The air compressor discharges saturated compressed air. Daha sonra, they will pass through desiccant beads in the drying tower. Bu yüzden, it will adsorb a large amount of water vapor. This water vapor will remain in the capillary pores of the adsorbent. The drying process will wait until the regeneration of the regeneration tower finishes. Daha sonra, start to cycle the switch.
(2) Desorption Process of Regenerative Desiccant Dryer
① First is the pressure release process of the desiccant dryer system. The regeneration tower must be reduced to atmospheric pressure. Discharge pressure and start the second process.
② Second is the thermal purging process. The blower is running. It inhales the ambient air. Then the heater will heat up. Daha sonra, enter the regenerative desiccant dryer to complete the thermal purge. Nihayet, remove and drain moisture.
③ Third is the cold purge process. The cooling process starts. Aynı zamanda, the heater stops working. The blower sucks the remaining airflow inside. These air streams flow through cooler adsorption towers. Nihayet, back to the blower. Gradually, it reduces the temperature of the desiccant beads.
④ Fourth is the boosting process. The regeneration exhaust valve closes. Aynı zamanda, the regeneration valve remains open. Çalışma basıncını artırın ve ona ulaşın.
⑤ Fifth is the standby process. Şu anda, the regeneration tower has finished pressure boosting. The regenerative air dryer waits for the switch.
⑥ Sixth is the TSE dew point energy-saving control process. It can carry out dynamic control according to the actual dew point. So it can save energy to the greatest extent.
⑦ Sonunda, it is the process of transformation. So it starts a new process of desiccant dryer system.
SSS
Evet. Its dew point can reach -70℃. But we usually only do -40°C. There is still some water pollution during the cold purge process. Öyleyse, it will increase very much power at this time. We recommend the micro air-loss type dryer if you need a -70℃ dew point.
Our regenerative desiccant dryer uses high-quality adsorbent. Its service life can reach 2 yıl. Elbette, we recommend installing precision filters in front of the regenerative air dryer.
