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%.

4 Benefits of Onsite Nitrogen Generators

On-site nitrogen generation has proven to be one of the most reliable ways to generate high-purity nitrogen. Below are some of the benefits of using this option:

1. Cost Savings

Generating nitrogen on-site is a more cost-effective option than purchasing the gas from vendors due to savings on the cost of transportation. Moving nitrogen gas between various locations in the country will require the services of trucking companies that charge a fair price for loads.

Industrial operators may also need to provide storage facilities within the site to house the containers. Moreover, there is a possibility of product loss during transit. NiGen offers high-purity nitrogen generator rentals at some of the best prices in the industry.

2. Time Savings

On-site nitrogen generation saves industrial users from downtime on critical operations that require the use of nitrogen. Operational downtime due to logistics issues with trucking nitrogen from vendor locations incurs huge losses for industrial users every year.

In contrast, having a stand-by nitrogen generation system ensures that you have a 24-hour supply of high-purity gas for your processes.

3. Safety and Reliability

On-site nitrogen generation systems are inherently safer than obtaining liquid or gaseous nitrogen from cylinders. Nitrogen gas leaks from damaged cylinders can be toxic to humans, particularly when it is present in confined spaces (N2 is known to displace oxygen in the lungs). Using a PSA or membrane filtration system for on-demand nitrogen gas generation may eliminate the need for pressurized nitrogen containers that may expose workers to excessive levels of inert bases.

Nitrogen generation systems from NiGen are ASME-certified for safety and reliability. They ensure reliable nitrogen gas production on land-based and offshore locations.

Additionally, industrial nitrogen generators that use hollow fiber membrane systems can provide nitrogen grades of up to 99.95% purity. These nitrogen generation skids are versatile, and easy to mount and transport according to your process needs.

4. Environment-friendly

Compressing liquid nitrogen into cylinders has adverse effects on the environment as it uses up a lot of energy. Trucking the gas over long distances also contributes to environmental pollution from the exhaust of vehicles.

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.
