VPSA Oxygen Generator System

The adsorber is equipped with a dedicated airflow distribution structure, ensuring uniform air flow across the chamber and improving molecular sieve utilization efficiency.

Designed with a vertical dual-bed structure, the adsorber is filled with activated alumina at the bottom to reduce moisture impact on molecular sieve performance. During regeneration, nitrogen is used for molecular sieve desorption, while clean air enables heatless regeneration of the alumina, jointly extending the service life of all adsorbents.

The system utilizes imported high-performance oxygen molecular sieves, field-proven in long-term industrial applications, ensuring stable and reliable operation. The specially formulated PSA-grade activated alumina effectively protects the molecular sieve adsorbent.

VPSA Oxygen Generator System

Introduction

The VPSA oxygen generator is an advanced on-site oxygen generation system designed for large-scale industrial applications, characterized by high efficiency and low operating costs. Comprising a blower, vacuum pump, cooler, adsorption system, oxygen buffer tank, and control system, it delivers a continuous and stable oxygen supply.

 

Widely utilized in industrial PSA oxygen generation solutions, the system provides reliable oxygen for sectors such as iron and steel smelting, chemical production, wastewater treatment, and other oxygen-intensive industries.

 

1. Large iron and steel smelting:

Delivers oxygen-enriched air to enhance combustion, reduce coke consumption, and increase production capacity.

 

2. Paper making and bleaching:

Provides stable oxygen for pulp bleaching, reduces the use of chlorine-based chemicals, and supports environmentally friendly production.

 

3. Non-ferrous metal smelting:

Oxygen supply accelerates smelting reactions, improves metal recovery, and reduces energy consumption.

 

4. Large chemical plants:

Supplies high-flow stable oxygen to support continuous and reliable chemical production.
