PSA Nitrogen Generator Applications
High-purity on-site nitrogen for demanding industrial processes:
The PSA (Pressure Swing Adsorption) nitrogen generator is an on‑site air separation unit that uses carbon molecular sieves (CMS) to selectively adsorb oxygen from compressed air. It continuously produces high‑purity nitrogen gas up to 99.9995% at ambient temperature.
The adsorbed oxygen is released by depressurizing the adsorption bed, allowing the system to regenerate and operate in a cyclical adsorption‑desorption process – ensuring uninterrupted nitrogen supply for industrial applications.
▸ Ideal for laser cutting, food packaging, electronics, and pharmaceutical manufacturing.
Membrane Nitrogen Generator – 95% Purity for Oil & Gas Field Operations
Our membrane nitrogen generator uses advanced hollow-fiber separation technology to deliver reliable 95% purity nitrogen directly at the wellsite. Designed for harsh oilfield environments, weisidun membrane systems feature rugged construction, simple operation with no moving parts, and diesel/gas engine drive options for completely off-grid deployment. With flow rates from 300 to 1,500 Nm³/h and discharge pressures up to 50 MPa, our systems meet the demanding requirements of pipeline purging, enhanced oil recovery (EOR), and tank inerting.
