Discover efficient and reliable Nitrogen Generator solutions for your industrial needs.
An industrial Nitrogen Generator is a sophisticated system designed to produce high-purity nitrogen gas on-site, directly from ambient air. This eliminates the need for bulky nitrogen cylinders or expensive liquid nitrogen deliveries, offering a cost-effective and continuous supply of N2. These systems are crucial for modern industrial nitrogen production, providing gas purity ranging from 95% to 99.999% depending on the application.
From a compact small nitrogen generator for specific lab tasks to large-scale N2 generator system installations for manufacturing plants, on-site nitrogen generation offers unparalleled control over supply and purity. It's an indispensable component for industries requiring inert atmospheres, purging, blanketing, or product preservation.
Our Nitrogen Generator primarily utilizes Pressure Swing Adsorption (PSA) technology, a robust and proven method for separating nitrogen from atmospheric air. This process is energy-efficient and highly reliable, ensuring consistent nitrogen purity.
· Air Compression: Ambient air is drawn in and compressed to a specified pressure (typically 7-10 bar). This raw material is readily available and free.
· Air Pre-treatment: The compressed air passes through a series of filters (particulate, coalescing, activated carbon) and an air dryer (refrigerated or desiccant) to remove moisture, oil, and other contaminants. This ensures the longevity and efficiency of the CMS.
· PSA Adsorption Towers: The cleaned air enters one of two adsorption towers, each filled with Carbon Molecular Sieve (CMS) – the core method. CMS has a microporous structure that preferentially adsorbs oxygen and other trace gases (like argon and CO2) while allowing nitrogen to pass through.
· Nitrogen Generation: As oxygen molecules adhere to the CMS, high-purity nitrogen gas exits the top of the tower and flows into a buffer tank.
· Regeneration: When one tower reaches saturation, the incoming air automatically switches to the second tower. The saturated tower is then depressurized to atmospheric pressure, releasing the adsorbed oxygen and regenerating the CMS for the next cycle. This "swing" in pressure gives the technology its name.
· Nitrogen Buffer & Storage: The produced nitrogen is stored in a buffer tank to ensure a continuous and stable supply at the required pressure and flow rate. Optional high-pressure boosters and storage tanks can be added for specific demands.
· Materials: High-grade stainless steel for pressure vessels, durable seals, and premium Carbon Molecular Sieve (CMS) for optimal adsorption.
· Testing Standards: All systems undergo rigorous testing according to ISO 9001 quality management, ASME standards for pressure vessels, and CE directives for safety. Each N2 generator system is factory-tested for purity, flow, and dew point before dispatch.
· Service Life: With proper maintenance, a Nitrogen Generator can have a service life exceeding 15 years, with CMS typically lasting 5-10 years before replacement is needed, depending on air quality and operating conditions.
Our Nitrogen Generator systems offer significant advantages over traditional nitrogen supply methods, ensuring operational efficiency and cost savings for various industrial applications.

· Pharmaceuticals: Inerting reactors, product transfer, packaging, laboratory applications.
· Chemicals & Petrochemicals: Tank blanketing, pipeline purging, fire suppression.
· Laser Cutting: Assisting gas for high-quality cuts and preventing oxidation.
· Oil & Gas: Well completion, pipeline purging, instrument air.
