99.999% Purity Nitrogen Generator
In modern industrial production, a stable nitrogen supply is essential for product quality and operational safety. As electronics manufacturing, advanced chemicals, and energy materials continue to expand, industries demand higher nitrogen purity, lower energy consumption, and long-term operational reliability.
Shenger Gas cryogenic air separation systems are engineered to deliver continuous and high-purity nitrogen at scale, making them ideal for large industrial facilities. Our "99.999% purity nitrogen generator" series is specifically designed for critical applications that require stable, high-purity inert gas supply on-site.
Working Principle & System Structure
Cryogenic separation cools atmospheric air to around −190°C and separates gases by the difference in boiling points. The process enables stable production of high-purity nitrogen.
Process stages:
- Air compression
- Precooling & purification (removal of H₂O, CO₂, hydrocarbons)
- Cryogenic heat exchange & liquefaction
- Rectification through distillation columns
- Nitrogen storage and distribution
System composition:
- Air compressor package
- Molecular sieve purification unit
- Cold box (heat exchangers + distillation columns)
- Liquid nitrogen tank / nitrogen buffer tank
- PLC-based automatic control & monitoring
