Oxygen Generators provide stable on-site oxygen supply with low cost, reliable purity, and continuous industrial production. Oxygen is produced directly from compressed air, helping reduce operating costs, eliminate cylinder or liquid oxygen delivery, and ensure uninterrupted production. Systems can be configured by capacity and purity to match different industrial requirements.
● PSA / VPSA systems for different oxygen demand
● Adjustable purity for industrial applications
● Modular design for easy installation and expansion
What Is an Oxygen Generator
An Oxygen Generator is an industrial gas system that produces oxygen directly from compressed air using PSA or VPSA technology. It separates oxygen from nitrogen and other gases to provide a stable, continuous on-site oxygen supply without relying on external delivery.
It is widely used in industrial applications that require consistent oxygen flow, controlled purity, and reliable long-term operation.

Oxygen Generator Types for Industrial Use
HUATAI provides three oxygen generation system types to match different production scales, installation conditions, and investment budgets. The selection is mainly based on required oxygen flow rate, purity level, and on-site deployment conditions.
PSA Oxygen Generator
Designed for small to medium oxygen demand with stable continuous operation.
Suitable for: small factories, aquaculture, wastewater treatment
Oxygen purity: typically 93% ±3%
Installation: skid-mounted, compact footprint
Key advantage: lower investment cost and simple on-site setup
Best choice when oxygen demand is stable but not at large industrial scale.
VPSA Oxygen Generators
Built for large-scale continuous oxygen supply with higher efficiency.
Suitable for: steelmaking, glass production, large chemical and mining projects
Oxygen capacity: high flow industrial demand
System design: modular plant-level configuration
Key advantage: lower energy consumption per Nm³ oxygen at large capacity
Best choice for industries requiring high-volume, continuous oxygen production.
Containerized Oxygen Generators
Integrated oxygen production system built inside a standard container structure.
Suitable for: remote sites, EPC projects, temporary or mobile deployment
Installation: plug-and-play, fast commissioning
Key advantage: transportable and reduced on-site construction work
Best choice when installation speed, mobility, or remote operation is a priority.
How Does an Oxygen Generator Work
Oxygen generators produce oxygen from ambient air through a continuous separation process. Air is compressed, purified, and processed using PSA or VPSA technology to separate oxygen from nitrogen. The oxygen is then delivered directly to storage or end-use systems, enabling stable on-site oxygen supply for industrial operations. Compared with cylinder or liquid oxygen supply, on-site generation reduces logistics dependence, improves supply stability, and supports lower long-term operating costs.
Still Relying on Oxygen Cylinders or Liquid Oxygen Supply?
Many industrial facilities still depend on oxygen cylinders or bulk liquid oxygen supply. While widely used, these methods can create supply interruptions, higher logistics costs, and limited control over long-term oxygen expenses. For continuous operations, it is important to evaluate whether the current supply method still meets efficiency and reliability requirements.

How to Choose the Right Oxygen Generator
The right oxygen generator depends on your required purity, flow rate, pressure, and operating conditions. Matching these parameters ensures stable oxygen supply, lower operating costs, and reliable long-term performance.
● Oxygen Purity: defines required oxygen concentration for the application.
● Flow Rate: determines total oxygen demand per hour.
● Pressure Requirement: matches oxygen output with process equipment conditions.
● Project Scale: helps determine system type: PSA, VPSA, or containerized.
● Installation Type: defines layout based on site space and engineering conditions.
Different combinations of these parameters determine the most suitable oxygen generator configuration for your application, whether PSA, VPSA, or containerized systems.
