VPSA Oxygen Plant 300 Nm3/hr with PLC Control for Industrial Use

VPSA (Vacuum Pressure Swing Adsorption) oxygen production equipment utilizes advanced adsorptive gas separation technology to efficiently produce oxygen with purity levels ranging from 80% to 95%. This system effectively separates nitrogen and moisture from air, making it ideal for various industrial applications.

GNEE's VPSA oxygen production equipment features a specially developed process flow for high-speed centrifugal blowers. This innovative application of high-speed direct-connected centrifugal blower technology reduces equipment wear and significantly extends operational lifespan.

As an energy-saving and environmentally friendly solution, GNEE's VPSA equipment offers 8-12% energy savings compared to traditional technologies. The system operates with low noise levels and features intelligent control, resulting in reduced overall oxygen production costs.

The VPSA oxygen generator operates using mature, reliable technology based on zeolite molecular sieve (ZMS) and vacuum regeneration system. The process consists of three main stages:

Ambient air is first filtered to remove impurities, then moderately compressed by the fan system. This pretreatment ensures clean air meets oxygen extraction requirements.

Pretreated air enters a container with zeolite molecular sieve, which selectively adsorbs nitrogen while allowing oxygen to pass through. The system removes residual moisture and carbon dioxide, producing oxygen-rich gas.

When zeolite becomes saturated with nitrogen, a dry-running vacuum pump reduces pressure to release adsorbed gases. The system includes a buffer tank to ensure continuous oxygen supply through repeated purification, adsorption, and desorption cycles.
