The 99.5% PSA Nitrogen Generator is designed to provide a stable, continuous, and cost-effective nitrogen supply for a wide range of industrial applications. By using Pressure Swing Adsorption (PSA) technology, the system separates nitrogen from compressed air through high-performance carbon molecular sieve (CMS), eliminating the need for traditional nitrogen cylinders or liquid nitrogen delivery.
The generator operates with a dual-tower adsorption system. During operation, compressed air enters one adsorption tower, where oxygen, moisture, and trace gases are selectively adsorbed by the CMS, while nitrogen passes through and is delivered to the outlet. At the same time, the second tower undergoes regeneration. A small portion of the produced nitrogen is used to release the adsorbed oxygen from the saturated CMS, and the exhaust gas is safely discharged into the atmosphere.
A PLC control system automatically switches the two towers every 45–60 seconds, ensuring uninterrupted nitrogen production and stable nitrogen purity at 99.5%. This process provides reliable performance, low energy consumption, fast start-up, and long service life, making it an ideal on-site nitrogen solution for industrial users.
To ensure stable nitrogen purity and efficient long-term operation, the nitrogen generator should be used under the following recommended conditions:
- Nitrogen purity: 99.5%
- Inlet pressure: 0.5–0.8 MPa
- Inlet temperature: ≤ 40°C
- Nitrogen dew point: ≤ -40°C
- Ambient temperature: ≤ 40°C
- Switching cycle: 45–60 seconds
- Voltage / frequency: 220V / 50Hz
- Noise level: ≤ 75 dB
For the best performance, the generator should be supplied with clean and stable compressed air. Proper pre-treatment, including air filtration and drying, is recommended to protect the carbon molecular sieve, improve nitrogen generation efficiency, and extend equipment service life.

In India’s hot climate, seasonal monsoon humidity, and fast-growing manufacturing environment, reliable compressed air pretreatment is essential for stable on-site nitrogen generation. The 99.5% PSA Nitrogen Generator is designed for users who need a continuous, economical, and dependable nitrogen supply without relying on cylinders or liquid nitrogen. With 99.5% nitrogen purity and a nitrogen dew point of ≤ -40°C, it is well suited for Indian industrial users that require general-purpose nitrogen for packaging, inerting, oxidation control, and production support.
Typical Applications
- Food and beverage packaging
- Chemical processing and inert gas blanketing
- Plastics and injection molding
- Metal processing and fabrication
- General electronics assembly
- Powder metallurgy and controlled-atmosphere production
- Laboratories and utility nitrogen supply
- Central industrial nitrogen systems for continuous plant use
Why It Fits Indian Working Conditions
- On-site nitrogen generation reduces dependence on cylinder delivery and liquid nitrogen logistics
- Suitable for Indian factories that need an economical and stable nitrogen source for daily production
- Works well for packaging, purging, blanketing, and oxidation reduction applications where 99.5% purity is appropriate
- A wide model range supports both medium and larger plant nitrogen demand
- In hot and humid conditions, proper filtration and drying help maintain CMS performance, nitrogen purity, and system life
Application Note
For the India page, this model is best positioned as an economical general-purpose nitrogen solution, rather than an ultra-high-purity nitrogen system. It is especially suitable for food packaging, plastics processing, chemical blanketing, metal fabrication, powder metallurgy, and general industrial utility nitrogen use. For India’s summer and monsoon conditions, the page should also emphasize the need for clean, dry, stable compressed air pretreatment, since humidity and inlet air quality directly affect nitrogen purity and CMS life.
