Nitrogen Generation
The Economical and Eco-Friendly Alternative to Traditional Nitrogen Delivery
Find out if nitrogen generation makes sense for your business.
What is nitrogen generation?
Nitrogen gas generation is a process that separates and captures the nitrogen molecules in the air, while disposing of the oxygen and trace gases. NITROCENTER® is a nitrogen generation system that delivers nitrogen on-demand, engineered to your application requirements.
The benefits of on-site nitrogen generation
Each industry and application will require varying nitrogen concentration levels, referred to as "purity." The ability to control purity, along with pressure and volume, is what drives rapid ROI.
- Save up to 90% vs. traditional delivery
- Reduce electricity consumption
- Stop frequent diesel truck deliveries
- Achieve ROI in as little as six months
- Eliminate safety risks from handling liquid nitrogen and gas cylinders
- Control your own nitrogen supply
Nitrogen generation that works for you
On-site nitrogen gas generation can be achieved through pressure swing absorption (PSA), or membrane separation technology. Purity Gas can deploy both, and the technology used is largely dependent on the purity required for your application.
A. Pressure Swing Absorption (PSA)
How it works: PSA systems use a carbon molecular sieve (CMS) and absorption principles to separate the nitrogen molecules from a compressed air supply.
Ideal for: High-flow applications requiring 95% - 99.999% nitrogen purity.
Key Features
NITROCENTER® systems based on PSA technology are centered around two design principles: High-Pressure Storage or On-Demand Generation, to offer cost-reducing options for low-volume and high-volume nitrogen users.
Below are the typical parameters for each principle. Every client is unique and your NITROCENTER® is always customized to your needs.
Design Principle
High-Pressure Storage
On-Demand Generation
How It Works
Generates nitrogen during no or low production use
Generates nitrogen as the process requires it
Nitrogen Pressure
High: Stored at 4,500 psig and regulated to the process requirement
Low / Mid: As needed up to 450 psig and regulated to the process requirement
Nitrogen Consumption
Less than 12 hrs/day
More than 12 hrs/day
B. Membrane Separation
How it works: Membrane systems use hollow fiber tubes and selective permeation to separate the nitrogen molecules from a compressed air supply.
Ideal for: Low-flow applications requiring 95%-99.5% nitrogen purity.

Nitrogen Generators vs. Nitrogen Generation Systems
A quick web search will display dozens of nitrogen generators for sale. These out-of-the-box products are just one component of an entire system. A nitrogen generation system not only contains all of the required components, but it’s designed as a cohesive solution that meets your technical requirements.
Purity Gas takes nitrogen gas generation to the next level. As your integration partner, we’re committed to customizing a system that maximizes ROI — bringing nitrogen generation down to the lowest possible cost.
Poor nitrogen system design can increase capital cost and cost of ownership by up to 800%.
How to select the right nitrogen generation provider
Just because your business consumes nitrogen doesn’t make on-site nitrogen generation a wise investment. A reputable nitrogen generation manufacturer will offer an initial assessment or comprehensive nitrogen audit to determine feasibility.
Key considerations when evaluating a nitrogen generation provider
Does the provider offer …
- Analysis of your current nitrogen usage?
- Technology and viability recommendations?
- The payback period and annual ROI of a system?
- Estimated carbon footprint reduction?
- A more detailed nitrogen audit?
