Piesoo is pleased to announce the successful installation and commissioning of our 200 m³/h zero purge blower purge desiccant air dryer at a leading chemical manufacturing facility in Vietnam.
The customer, a well-established chemical plant specializing in industrial gases, was facing high operating costs due to excessive compressed air consumption from their existing drying system.
After evaluating multiple suppliers, they chose Piesoo for our zero purge technology, energy efficiency, and proven export experience.
The Challenge
In chemical manufacturing, compressed air is often used for:
- Instrumentation and control valves
- Pneumatic conveying of sensitive materials
- Process air for chemical reactions
The customer’s existing desiccant air dryer consumed 15-20% of rated flow as purge air, resulting in significant energy waste and higher operating costs.
The Solution
Piesoo supplied and installed our 200 m³/h zero purge blower purge desiccant air dryer, designed with:
| Feature | Benefit |
| Blower purge regeneration
|
Uses ambient air for regeneration – no compressed air loss |
| Zero purge air consumption
|
Saves 15-20% of compressed air vs conventional dryers |
| Stable -40°C dew point
|
Meets chemical industry requirements for instrument air |
| PLC automatic control
|
24/7 reliable operation with minimal supervision |
Customer Feedback

About Piesoo Zero Purge Blower Purge Technology
Unlike traditional heatless desiccant dryers that consume 15-20% of rated flow as purge air, Piesoo’s blower purge dryer uses an electric blower to draw ambient air for regeneration. This design:
✅ Eliminates compressed air loss – Zero purge consumption
✅ Reduces operating costs – Lower energy bills over the equipment lifetime
✅ Ideal for large flows – Best for continuous 24/7 operations
✅ Proven reliability – Simple design with fewer wearing parts
