Twin Tower PSA Oxygen Generator

Name: China Twin Tower PSA Oxygen Generator Suppliers Factory - NEWTEK INDUSTRY
Brand: NEWTEK
SKU: 294450545

The Twin Tower PSA Oxygen Generator is an industrial-grade on-site oxygen generation system designed to deliver a stable and continuous oxygen supply with high purity and low operating cost.、By adopting advanced Pressure Swing Adsorption (PSA) technology and a dual-tower alternating adsorption structure, the system efficiently separates oxygen from compressed air, providing oxygen purity up to 93% ±2%.Engineered for long-term, 24/7 operation, the twin tower PSA oxygen generator is widely used in industries such as steelmaking, non-ferrous metallurgy, chemical processing, medical gas supply, wastewater treatment, glass production, and industrial combustion enhancement.Compared with traditional bottled oxygen or liquid oxygen supply, it significantly reduces oxygen procurement costs, logistics dependence, and safety risks.

Twin Tower PSA Oxygen Generator Working Principle

Air Compression & Pretreatment

Ambient air is compressed and purified to remove dust, moisture, and oil before entering the PSA system.

Selective Adsorption

Compressed air flows into the adsorption tower, where molecular sieve selectively adsorbs nitrogen under pressure, allowing oxygen to pass through.

Pressure Swing Regeneration

When adsorption is complete, the system depressurizes the saturated tower to release nitrogen and regenerate the molecular sieve.

Continuous Twin-Tower Operation

The two towers alternate between adsorption and regeneration, ensuring stable and uninterrupted oxygen production.
