On-site nitrogen systems from NiGen International generate a dependable and economical supply of nitrogen gas in the quantity and purity necessary for any application. Our container nitrogen generators are manufactured to the highest quality standards, ensuring long operational lifespans with minimal service requirements and maximum energy efficiency.
NiGen International designs and manufactures the following types of nitrogen generation systems:
PSA Nitrogen Generation Systems
PSA (Pressure Swing Adsorption) Systems generate nitrogen by separating it from the oxygen in ordinary air. PSA nitrogen generation systems are a safe and reliable method for generating high purity nitrogen gas on location for laboratories and other industries that require N2 in their applications. They are a cost-effective alternative to delivered gas.
Membrane Nitrogen Generators
Membrane generators force compressed air into a vessel containing a hollow tube surrounded by a polymeric hollow fiber. The hollow fibers selectively permeate oxygen, water vapor, and other impurities out of their sidewalls, allowing nitrogen to flow through the center and emerge as gas.
How NiGen Membrane Nitrogen Generators Work
Our nitrogen membrane technology is an efficient alternative to PSA systems. We use high-selectivity hollow fiber membranes for nitrogen gas separation. These semi-permeable layers are made of flexible, cylindrical filaments with pore sizes from 0.03 to 10 microns.
Dry, compressed air is applied over the material to separate nitrogen gas which is housed in a cylindrical vessel. The nitrogen membrane allows N2 to pass through while inhibiting oxygen, inert gases, water vapor, and other impurities. The membrane selectivity is dependent on pore size. Membrane nitrogen gas generators can produce purities up to 99.95%.

Mobile Membrane Nitrogen Generation Systems
These are membrane nitrogen generators mounted on either trailers or skids for portability. We design our mobile nitrogen generators to customer specifications, maximizing nitrogen generation within a predefined footprint.
Advantages of On-site Membrane Type Nitrogen Generators
- Better Quality Nitrogen – Industrial nitrogen generators that use hollow fiber membrane systems can provide nitrogen grades of up to 99.95% purity.
- Less Waste – Because it uses atmospheric air, there is no notable waste associated with the usage of these on-site nitrogen systems.
- Consistent Costs – There is no haggling with suppliers when your oil and gas or industrial application relies on container nitrogen generation units instead of compressed cylinder delivery.
- Mountable Skids – These nitrogen generation skids are versatile, and easy to mount and transport according to your process needs.
Combine our industrial nitrogen gas generators with our mobile air compressors and twin tower desiccant dryers for the best quality process air that will help prevent system decay and costly downtime.
Nitrogen Container Systems
These nitrogen generation systems are designed to fit a 10-, 20-, or 40-foot steel ISO container or similar structure that can be easily transported on a truck. When the nitrogen container unit reaches the end-user’s facility, it only requires an electrical hookup to begin generating nitrogen on-site. In addition to the cost-savings, ease of implementation is one of the main benefits of our on-site nitrogen generators.
Easy Nitrogen Generator Installation
Because of the modular design of our membrane nitrogen generators, introducing nitrogen gas into your O&G process is easy. Contact a member of our technical team to learn how easy nitrogen generator installation is with our external container hookups.
We also have certified technicians who can service your compressor and nitrogen gas generators.
