Modular PSA nitrogen generator market to reach $466 million by 2032

The global market for modular Pressure Swing Adsorption (PSA) nitrogen generators is projected to grow at a compound annual growth rate (CAGR) of 6.44% from 2026 to 2032. According to a report by QY Research, the market size is expected to reach approximately $321 million in 2026 and expand to $466 million by 2032.

These on-site systems use compressed air and carbon molecular sieves to supply nitrogen continuously. Key advantages include a small footprint, ease of installation, and scalability through standardized modules that allow for capacity adjustments without stopping the entire system. The technology is widely used in sectors such as food and beverage packaging, semiconductor manufacturing, chemical processing, pharmaceuticals, and lithium-ion battery production.

Major global players in the market include Atlas Copco, Parker Hannifin, and Air Products, who leverage extensive service networks and integrated gas processing systems. Specialized manufacturers like Generon and Peak Scientific compete by offering high-purity, compact solutions. Additionally, Chinese manufacturers such as Shanghai Ruiqi and Shanghai Lianfeng are increasing their market presence through cost advantages and localized engineering services.
