Engineering Expertise. Certified Quality. Trusted Worldwide.
The HOLANG nitrogen system features three key components:
an air compressor, an air purification unit, and a modular nitrogen generator.
Powered by Pressure Swing Adsorption (PSA) technology, our system uses clean compressed air and high-efficiency Carbon Molecular Sieve (CMS) to deliver continuous, high-purity nitrogen.
Oxygen and impurities are selectively removed under pressure, and the system regenerates automatically — ensuring stable performance, low maintenance, and 24/7 nitrogen supply for your production line.
