Air is made up of roughly 78% nitrogen, 21% oxygen and 1% other trace gases, so a nitrogen generator for your own supply makes a lot of sense.

Nitrogen generators: onsite nitrogen supply for industry

Nitrogen generators produce high-purity nitrogen on-site, offering a cost-effective and reliable alternative to bottled or liquid nitrogen. Ideal for applications in food packaging, electronics, manufacturing, and more. These systems provide nitrogen exactly where and when it’s needed, without the cost and hassle of external supply.

With easy installation and low maintenance, nitrogen generators ensure consistent nitrogen output while reducing your operational costs and environmental footprint.

On-site nitrogen generation vs bottled or liquid supply


Traditionally, nitrogen is supplied in gas bottles, cylinder banks, or as liquid nitrogen and is often at ultra-high purities (99.999%) that exceed the needs of many applications. This results in unnecessary costs, including:

  • Expensive transport and delivery charges
  • Cylinder rental fees
  • Losses due to boil-off in liquid tanks
  • Wasted nitrogen in part-full bottles
  • Rising wholesale nitrogen prices

At PPS, we’ve helped many companies take control of their nitrogen supply with on-site generation. By producing nitrogen on demand, businesses reduce waste, save money, and improve reliability.

Key benefits of on-site nitrogen generation

  • Significant cost savings over traditional supply
  • No delivery, rental, or handling fees
  • Reduced health and safety risks from gas deliveries
  • Continuous, dependable nitrogen supply
  • Long equipment service life with minimal maintenance
  • No boil-off losses or returned partially used bottles
  • Make nitrogen overnight for use during the day
  • No production downtime for bottle changeovers

Nitrogen generation for your industry

Whether used for back pressure, modified atmosphere packaging, or purging systems, nitrogen plays a vital role across industries:

  • Food and drink: packaging, preservation, breweries
  • Pharmaceutical and healthcare: sterile packaging, lab processes
  • Electronics: soldering, testing, component storage
  • Chemical and plastics: inerting, blanketing, safety
  • Laser cutting: precision cutting with minimal oxidation
  • Glass, ceramics and steel: processing and atmosphere control
  • Construction and fertiliser: propellant and stabiliser use

Wherever your industry uses nitrogen, an on-site nitrogen generator from PPS ensures a safer, more efficient, and cost-effective supply.

Frequently Asked Questions for Nitrogen Generators

What is a nitrogen generator?

A nitrogen generator is a system that separates nitrogen from compressed air to produce high-purity nitrogen on-site. It provides a reliable and cost-effective alternative to bottled or liquid nitrogen.

How much does a nitrogen generator cost?

The cost depends on the flow rate, purity, and system size. Small units start from a few thousand pounds, while larger industrial systems may cost tens of thousands. PPS can provide a tailored quote based on your needs.

Do nitrogen generators need compressed air?

Yes, nitrogen generators require a compressed air supply. The air is filtered and processed to separate the nitrogen, so pairing the generator with a reliable air compressor is essential.

How much nitrogen can a nitrogen generator produce?

Output varies by model, ranging from a few litres per minute to hundreds of cubic metres per hour. PPS can size a system based on your application, usage, and required purity.
