PEHB series

Compressed air with high moisture flows into the drying tower. While it moves from the bottom to the top of the tower, moisture is adsorbed by the charged desiccant, producing dry compressed air. While the air is being dried in the drying tower, other towers engage in regeneration process to remove adsorbed moisture. The regeneration process is divided into heating and cooling processes. During the former process, air is sucked in from the outside, using a blower. Then, it is heated through a heater, heating the desiccant in the regeneration
tower. After moisture is removed, it is discharged to the outside through a muffler at the bottom of the regeneration tower. Once the heating process is complete, a cooling process begins. The heated descant is cooled down, using a part of the dry compressed air from the drying tower. Then, it is discharged to the outside through a muffler at the bottom of the regeneration tower. Once the cooling process is completed, the desiccant regeneration process from the regeneration tower is also finished. The purge valve from the regeneration tower is
closed. Then, dynamic pressure process pressurizing regeneration tower starts. Once the dynamic pressure process is done, two towers are transferred. In the drying tower, then, the regeneration process is executed. In the towers where such regeneration process is completed, drying process is executed.

A series of above processes are automatically repeated according to specific time and sequence, producing dry air consecutively. In terms of an operating cycle, it is basically operated for 8 hours. Drying process is executed by two towers (4 hours each). Specifically, itis heated for 2 hours and 30 minutes and cooled for 1 hour and 27 minutes with 3-minute dynamic pressure.
