The KOTECH Zero Purge Blower Heated Desiccant Air Dryer is designed to deliver a continuous supply of ultra-dry compressed air while minimizing operating costs. By utilizing ambient air for regeneration, the system eliminates compressed air loss during regeneration, significantly improving overall system efficiency.

Engineered for demanding industrial applications, the dryer provides a stable pressure dew point of -40°C as standard, with an optional -70°C version available for critical processes requiring exceptionally dry compressed air.

Why Choose KOTECH?

Zero Compressed Air Loss

How It Works

The KOTECH dryer operates with two desiccant towers.

1. Adsorption
   Wet compressed air passes through one tower where moisture is adsorbed by the desiccant.
2. Regeneration
   Ambient air is drawn in by the blower, heated, and directed through the saturated desiccant to remove accumulated moisture.
3. Cooling
   The regenerated desiccant bed is cooled and prepared for the next drying cycle.
4. Automatic Switching
   The PLC automatically switches between towers, ensuring an uninterrupted supply of dry compressed air.
