Industrial nitrogen generators allow companies to produce nitrogen gas on-site, eliminating the need for cylinders or external supply.
This solution improves safety, reduces costs, and ensures continuous production.
How an Industrial PSA Nitrogen Generator Works
Industrial PSA nitrogen generators operate through a pressure swing adsorption (PSA) process that uses carbon molecular sieves (CMS) to separate nitrogen from compressed air.
1. Compressed Air
Air is compressed and directed into the adsorption columns, where the gas separation process begins.
2. Gas Separation
Carbon molecular sieves retain oxygen, carbon dioxide and other gases, while nitrogen is separated and isolated.
3. High-Purity Nitrogen Production
Nitrogen is collected and made available for continuous use in industrial and laboratory processes.
4. System Regeneration
The columns automatically alternate to ensure continuous, stable, and uninterrupted operation.

No need for handling, storage, or transportation of gas cylinders, resulting in increased safety and operational simplicity.
Reduced operating costs
Lower costs related to gas supply and logistics, with a fast return on investment.
High-purity nitrogen
Nitrogen is produced with consistently high purity levels, ideal for industrial and laboratory applications.
Applications of Industrial Nitrogen Generators
Food packaging and bottling
Nitrogen is used to create protective atmospheres in packaging and bottling processes. It helps preserve product quality and extend shelf life.
Welding and controlled atmosphere furnaces
Nitrogen is used to create protective atmospheres in welding and heat treatment processes. It reduces oxidation and improves product quality and reliability.
Electronics industry
Nitrogen is used to create controlled atmospheres in soldering and electronics manufacturing processes. It reduces oxidation and improves joint quality.
Eyewear Industry
Controlled atmospheres with nitrogen and hydrogen are used for precision welding. This ensures clean joints, prevents oxidation, and guarantees high-quality finishes.
On-Site Nitrogen production: technology and operation
ILT Energia nitrogen generators use PSA technology (Pressure Swing Adsorption) to separate nitrogen from compressed air, producing high-purity gas directly at the point of use.
The system is composed of columns filled with carbon molecular sieves (CMS), which selectively adsorb oxygen, enabling continuous, stable, and reliable nitrogen production.
Thanks to the alternating operation of the columns, the system ensures a constant gas supply without interruptions, eliminating the need for cylinders or external suppliers.
These generators deliver high efficiency, precise purity control, and maximum operational safety, making them suitable for a wide range of industrial applications.
Technical specifications of Nitro Series nitrogen generators
Nominal flow rates in the table refer to 8 barG compressed-air inlet pressure and 6 barG nitrogen outlet pressure. Purity and flow rate must be considered together for each model.
The technical data sheet provides indicative flow-rate correction factors relative to the nominal value: 1.15 at 10 barG inlet / 8 barG outlet; 1.10 at 9 / 7 barG; 1.00 at 8 / 6 barG; 0.85 at 7 / 5 barG; 0.75 at 6 / 4 barG.
