PHL series is used in various fields such as food & beverage, pharmaceuticals, petrochemicals, electronics & semiconductor and medicine
GSA’s desiccant air dryer is able to provide even super-dry compressed air according to user needs
Why Desiccant Air Dryer?
A refrigerated air dryer chills and dehumidifies compressed air, using a refrigerant. To prevent condensate generated while cooling compressed air from being frozen or a heat exchanger from being frozen-burst, dew points are usually kept at 0℃ or higher. For moisture-sensitive processes, therefore, a desiccant air dryer is essential.
In general, a desiccant air dryer offers -40℃ or lower temperature of dew points. It is used in various fields such as food & beverage, pharmaceuticals, petrochemicals, electronics & semiconductor and medicine. In these industries, even a small amount of water might result in process discontinuance or product defect. Therefore, a highly reliable desiccant air dryer is a must-have system.
GSA’s desiccant air dryer is able to provide even super-dry compressed air (-100℃ or below) according to user needs. We have enhanced customer satisfaction through the design of diverse desiccant air dryer systems.

Operating Mechanism
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. During the regeneration process, dry compressed air from the drying tower is partially used. The dry compressed air is discharged to the outside through a muffler at the bottom of the regeneration tower after moisture adsorbed into the desiccant is removed. Once the regeneration tower process is complete, 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 10 minutes. Drying process is executed by two towers (5 minutes each). Specifically, it is regenerated for 4 minutes with 1 minute dynamic pressure.
