Complete Nitrogen Gas Generator System
HOLANG’s nitrogen generation system consists of three core components:
🔹 1. Air Compressor
Delivers clean compressed air as the source gas.
🔹 2. Air Purification Unit
Removes oil, moisture, and dust to protect the system.
🔹 3. Modular Nitrogen Generator
Uses PSA (Pressure Swing Adsorption) and Carbon Molecular Sieve (CMS) to separate nitrogen from air.
🔬 PSA Technology in Action
Oxygen and other impurities are selectively removed under pressure
Nitrogen passes through as a clean, high-purity gas
The system regenerates automatically — ensuring 24/7 operation
✅ Key Advantages
Nitrogen purity up to 99.999%
Fully automatic and low maintenance
Continuous on-site nitrogen supply
No more gas cylinders or delivery delays
