Oil-Free Nitrogen Generator

In industries such as food processing, electronics, lithium battery production, and metal heat treatment, even trace oil contamination or impurities can negatively affect product quality and equipment lifespan. Selecting a safe and reliable Oil-free nitrogen generator helps minimize contamination risks, reduce operating costs, and maintain a consistently stable process environment.

Shenger Gas utilizes purified ambient air as the feed source and avoids lubrication oil throughout the compression stage. This inherently eliminates oil-related risks. Combined with high-performance carbon molecular sieve (CMS) and intelligent control technology, our system delivers an optimal balance between purity and energy efficiency-an ideal on-site nitrogen solution for modern industrial facilities.

Operating Principle & System Configuration

The Oil-free nitrogen generator applies PSA (Pressure Swing Adsorption) technology:

1. Oil-free air compressor supplies clean compressed air
2. Pre-filtration and refrigeration drying remove moisture and impurities
3. Air enters dual CMS adsorption vessels
4. CMS selectively adsorbs oxygen; nitrogen is delivered as product gas
5. Automatic vessel switching ensures continuous operation

Main system modules:

• Oil-free air compressor
• Multi-stage filtration + refrigerated air dryer
• Dual adsorption towers with CMS
• High-performance valve blocks + PLC control
• Nitrogen buffer tank + online purity monitoring (optional)
