On-site Nitrogen Generators

Generating nitrogen on-site with PSA nitrogen generators is more cost-efficient than buying nitrogen cylinders or arranging gas deliveries. When nitrogen is purchased from third-party vendors, costs include trucking, handling, and storage. Moving compressed air or nitrogen between regions requires logistics support, and that adds up quickly.

Industrial operators also need storage areas for nitrogen cylinders, adding to space and infrastructure demands. There’s also a chance of nitrogen loss during transfer or storage. With a nitrogen solution from NiGen, operators avoid these added costs. Our pressure swing adsorption (PSA) systems offer a more direct, lower-cost method of generating gas right where it’s used.

On-site generation using carbon molecular sieve material allows for the separation of nitrogen molecules from atmospheric air, producing a steady stream of usable gas without external supply chains.

NiGen offers high-purity nitrogen generator rentals at some of the best prices in the industry.

Industrial sites often face delays waiting for gas deliveries. Downtime affects productivity, especially when nitrogen is essential to the operation. With on-site PSA nitrogen systems, businesses maintain a continuous supply of gas without depending on delivery schedules.

This method supports 24/7 operation by removing delivery bottlenecks. On-demand systems filter compressed air through pressure swing adsorption units, generating gas immediately for use in production. NiGen’s systems allow facilities to keep nitrogen flowing through pipelines or directly to pneumatic tools, packaging equipment, and other nitrogen-reliant systems.

In contrast, having a stand-by nitrogen generation system ensures that you have a 24-hour supply of high-purity gas for your processes.

Handling pressurized nitrogen cylinders or liquid nitrogen involves safety risks—especially in enclosed areas. Using a PSA or membrane filtration system for on-demand nitrogen gas generation may eliminate the need for pressurized nitrogen containers that may expose workers to excessive levels of inert bases. Leaks can lead to oxygen displacement, which poses serious health risks. On-site systems minimize that risk.

PSA nitrogen generators produce nitrogen from atmospheric air using carbon molecular sieve materials that selectively capture oxygen, leaving a high-purity gas stream of nitrogen. These units remove the need for high-pressure containers and are easier to monitor and maintain. NiGen’s nitrogen generators are ASME-certified and field-tested in both land-based and offshore operations.

Our membrane and PSA nitrogen systems provide ultra high purity nitrogen (up to 99.999% depending on the application) while supporting reliable nitrogen use across different industries, from electronics to petrochemicals.

Transporting nitrogen in bulk and compressing it into cylinders is energy-intensive. Trucking contributes to emissions, and liquid compression uses large amounts of electricity.

On-site nitrogen generation with a PSA nitrogen generator significantly reduces environmental impact. There’s no transport, no offloading, no risk of cylinder waste. Instead, nitrogen is pulled from atmospheric air, purified on the spot, and sent directly into your compressed air system. This model supports sustainable practices by lowering fuel use, emissions, and energy demand over time.
