Holtec Membrane Nitrogen Generators:

Efficiency & Safety

Membrane System Working Principle

Holtec's membrane nitrogen gas generators employ hollow fiber polymer membrane modules to precisely separate nitrogen gas. Compressed air enters the system at a typical feed air pressure of 125 psig/8.6 bar(g). The membrane's selective permeability allows the passage of nitrogen molecules, while allowing oxygen and water molecules to permeate across the fiber wall thereby creating a high purity nitrogen product stream. Simultaneously, the oxygen-enriched waste air stream is released at atmospheric pressure.

Through meticulous customization of the feed air pressure, temperature, purity, and membrane characteristics, our generators consistently achieve very good results for a moderate capital investment. This level of precision ranges from a reliable 95% up to 99.5% nitrogen purity.


Features and Benefits

Discover the exceptional features and benefits that make Holtec membrane nitrogen generators the top choice for on-site nitrogen production. Our commitment to innovation and excellence is evident in our technology, which enhances efficiency, safety, and cost-effectiveness in nitrogen supply.


Holtec membrane nitrogen generators deliver 95-99.5% nitrogen purity and yield, optimizing your process performance. The ability to tailor product purity and flow rates to your specific application ensures a nitrogen solution that meets your needs with the lowest possible operating costs.

Ease of Use


Our nitrogen generator systems arrive fully equipped and ready for seamless connection to your compressed air supply. Thanks to the convenience afforded by our membrane nitrogen systems, startup is as straightforward as pressing a button or opening a valve. Minimal maintenance, primarily involving filter replacements every three to twelve months, ensures your operations run smoothly and efficiently.

Cost Savings

Generating nitrogen on-site with a Holtec Membrane Nitrogen Generator presents significant cost reductions. Bid farewell to the difficulties, safety concerns, and logistical challenges associated with high-pressure nitrogen bottles or liquid nitrogen procurement.


Each Membrane Nitrogen Generator undergoes rigorous testing and meticulous fine-tuning. This results in precise calibration to meet your specific nitrogen flow rate and purity requirements. Our established track record of reliability guarantees a consistent and dependable nitrogen supply for your processes.  You may therefore rest easy that your nitrogen generator will arrive on-site already fine-tuned for your application.

Say goodbye to the risks associated with storing and handling high-pressure nitrogen bottles or liquid nitrogen. On-site nitrogen production enhances workplace safety by significantly reducing the need for transportation and storage of potentially hazardous materials.

Environmental Impact

Generating your own nitrogen with a Holtec generator requires less energy than the fractional distillation method employed by bulk gas suppliers. It also requires no trucks burning fossil fuels to deliver it to you.  By adopting on-site nitrogen production, you actively contribute to a more sustainable future. The reduction in transportation-related emissions and waste associated with traditional nitrogen sourcing positively impacts your carbon footprint, promoting environmental responsibility.
