Nitrogen generation on site
If nitrogen is required for your specialized process, our on-site nitrogen generators are the ideal solution, providing excellent continuous nitrogen supply and consistent purity in a compact and easy-to-operate package. No moving parts and a simple breakaway process ensures reliable operation and minimal maintenance requirements. The equipment operates quietly and can be installed in your production hall.
NGM⁺ lower total cost of ownership, requires 20% less air intake and eliminates the need for an air intake heater.
Continuous supply of dry, high-quality nitrogen with stable purity ensures your uninterrupted production. Soft start protects diaphragm and prolongs life.
The quiet operation allows you to install the machine in the production hall. And the constant flow feature eliminates the need for external storage tanks.
Nitrogen plays an important role in many industries and operations such as oil and gas, electronics, food and beverage packaging, chemical manufacturing, pharmaceuticals, laser cutting, wastewater treatment, and many others.
While buying or leasing nitrogen is always an option, costs can add up quickly. On-site nitrogen generation is a significantly better option when it comes to efficiency, total cost of ownership, employee safety and environmental impact. Additionally, with on-site nitrogen generation, you have complete control over the purity, pressure and volume of nitrogen produced for your specific application.
Self-production of nitrogen using compressed air
On-site nitrogen generators can utilize any of the following technologies:
PSA technology: Nitrogen generators with this technology can achieve the high purity (up to 99.999%) and high flow rate (1100 Nm³/h) required by the electronics, chemical and pharmaceutical industries. An on-site nitrogen generator using this technology consists of two connected towers that produce a near continuous flow of nitrogen.
Membrane technology: The nitrogen produced by this method can reach a purity level of 95% – 99.5% (adjustable), with a flow rate of up to 500 m³/h. This is ideal for fire protection, injection molding and food preservation applications. On-site nitrogen generators with diaphragm technology offer the advantages of a small footprint, low maintenance and low energy requirements.
For PSA nitrogen generators and membrane nitrogen generators , attention must be paid to the intake air to ensure that the on-site nitrogen generators can achieve the required gas purity. For PSA nitrogen generators, the compressed air flowing into the nitrogen generator needs to be kept clean and dry. The temperature and pressure of the intake air must also be controlled. This can be accomplished by installing an air dryer between the compressor and the on-site nitrogen generator. For diaphragm nitrogen generators, the intake air also needs to be kept clean and dry to prevent clogging.

Independent Nitrogen Production Industry and Application
Nitrogen storage tanks in the oil and gas industry : use nitrogen to purge compressor systems, pipelines and generators to minimize the risk of explosion or fire. Nitrogen is also used in oil and gas drilling.
Electronics : Nitrogen is used for lead-free soldering of circuit boards or other small components to prevent oxidation, and inertization with nitrogen improves the integrity of the joint.
Food and Beverage Packaging : Nitrogen is used in different stages of beverage production, handling and packaging. Why use nitrogen? Due to its inert, colorless and odorless properties, nitrogen gas is used to displace or replace air to reduce negative effects on the final product. In fruit juices, for example, the oxidation of vitamin C may be one of the decisive factors. Use of nitrogen in tanks, pipes, and bottles prevents this oxidation reaction from occurring. To remove dissolved oxygen from the juice, nitrogen is passed through the liquid, creating oxygen-carrying bubbles that then extract the oxygen from the juice. In the brewing industry, nitrogen is used to prevent oxidation so that fewer additives can be used. In addition, the acidity, color, aroma and natural flavors of the wine will be well preserved. The use of nitrogen will allow longer storage times without altering the main qualities of the wine. Nitrogen is practically insoluble in water, making it ideal for transferring wine. To ensure hygiene, the bottles are purged and dried with nitrogen before filling. Dries faster than normal air because the production process of the on-site nitrogen generator makes it a very dry gas. Finally, after filling and before placing the cork, the bottle is purged with nitrogen to avoid trapped air in the neck.
Laboratory : Compositional analysis using nitrogen gas. High-purity nitrogen is used as a carrier gas for precision instruments such as gas chromatography instruments, chemical analysis, spectrometers and thermal analyzers.
Fire Prevention : Combustible material, ignition source, and oxygen combine to create risk of fire. But if oxygen is replaced by nitrogen, the risk of fire or explosion is reduced. The maximum oxygen concentration (MOC) is the concentration at which a substance can no longer burn. Reducing the oxygen concentration below the MOC prevents explosions and fires. (MOC levels depend on the substance.)
Pharmaceutical industry : Oxygen and moisture can cause degradation and failure of pharmaceuticals. In addition, oxygen can trigger various harmful side reactions during drug production. The use of nitrogen during production and packaging can be largely avoided.
Nautical Shipping : Nitrogen is used to prevent or slow down the degradation of cargo such as food. On petrochemical tankers, nitrogen is used to reduce the risk of explosion or fire during unloading of gas cargoes.
Traditional Industry : Nitrogen is used in many metal heat treatment activities such as annealing, hardening, sintering. Also used for welding, brazing and brazing.
Cleaning: Nitrogen is used to clean the surface of heat-treated metal parts to prevent metal oxidation.
Carbonization: Carbonization is another application where nitrogen is often used because an oxygen-free atmosphere is required during the carbonization process.
Injection Molding: Nitrogen is often used as an assist gas during injection molding to prevent oxidation of the plastic and give the mold a clean surface finish. Nitrogen is also injected with the plastic, creating air channels that reduce the amount of plastic needed without sacrificing strength.
