The PPNG 1–5.5 HE uses Pressure Swing Adsorption (PSA) technology to separate nitrogen from compressed air.

 

Step 1 – Compressed Air Intake
Clean compressed air enters the nitrogen generator.

 

Step 2 – Air Separation
The air passes through vessels containing Carbon Molecular Sieves (CMS).

 

Step 3 – Oxygen Adsorption
The CMS selectively adsorbs oxygen and other gases while allowing nitrogen to pass through.

 

Step 4 – CMS Regeneration
The vessels alternate between pressure levels to regenerate the CMS and maintain continuous operation.

 

Step 5 – Nitrogen Delivery
Purified nitrogen is delivered at the required purity for the application.

The PPNG 1–5.5 HE combines compact installation with efficient nitrogen production for low-flow industrial requirements.

 

High-Purity Nitrogen
Produces nitrogen with selectable purity up to 99.999%.

 

Compact Footprint
Its space-saving design makes it suitable for installations with limited available space.

 

Energy-Efficient Operation
The optimized PSA cycle and Economizer function help reduce air and energy waste.

 

Better Supply Control
Generate nitrogen on-site and reduce dependence on cylinder deliveries.

 

Advanced Monitoring
Optional purity, flow, and pressure dew point monitoring provide greater process visibility.

 

Remote Access
The advanced controller provides system information, alerts, and remote monitoring capabilities.
