Smarter Gas Supply Starts On Site

Nitrogen gas is typically produced using cryogenic air separation or Pressure Swing Adsorption (PSA). Cryogenic plants cool air until the components liquefy and can be separated, while PSA systems, such as our i-Flow, use carbon molecular sieve to selectively adsorb oxygen, delivering high‑purity nitrogen on demand.

Nitrogen gas is not flammable. It is an inert, non-combustible gas that doesn’t burn or support combustion. It makes up roughly 78% of the Earth’s atmosphere and it can be used to extinguish fires or to create inert environments to prevent explosions.

Yes, nitrogen is considered an inert gas under most industrial conditions. It does not readily react with other substances, which is why it is widely used to create oxygen‑free environments that prevent oxidation, combustion, or chemical degradation.

Nitrogen is ever so slightly lighter than air, but only by a small margin. Air is a mixture of gases (mainly nitrogen and oxygen), so nitrogen generally behaves similarly and disperses quickly in open or ventilated areas.

Nitrogen itself is not toxic, but it can be dangerous in confined spaces because it can displace oxygen, creating an asphyxiation risk without warning. Since it is colourless and odourless, proper ventilation and oxygen monitoring are essential when working around high‑purity nitrogen.

For organisations that use nitrogen regularly, generators often provide significant cost savings over time by eliminating cylinder rental fees, delivery costs, and supply disruptions.

Depending on the model and application, Peak nitrogen generators can typically produce nitrogen with purity levels ranging from 95% to 99.999%.

Modern nitrogen generators, especially modular PSA systems like the PEAK Gas i-Flow range are designed for straightforward servicing. They feature easy maintenance routines and minimal downtime, ensuring reliable operation without the complexity of traditional bulk supply systems. Their modular and expandable design also makes them future-proof, allowing additional capacity to be added as demand grows without the need to replace the entire system. This scalability helps protect the initial investment, reduces long-term capital costs, and delivers significant savings over the lifetime of the equipment.

With proper maintenance, a PEAK Gas nitrogen generator can provide many years of reliable service, often delivering a strong return on investment over its operational lifespan.
