How Do On-Site Nitrogen and Oxygen Generators Work?

On-site nitrogen and oxygen generators take ordinary compressed air and separate it into high-purity nitrogen or oxygen using a process called Pressure Swing Adsorption (PSA). The result is a continuous, reliable gas supply at the purity and flow your operation needs, without truck deliveries, cylinder swaps, or liquid tanks. Ingersoll Rand uses this core PSA technology in its on-site gas systems, including OG Series on-site oxygen generators and high-pressure nitrogen solutions, to keep critical operations running efficiently and safely.

 

Our Range

Let’s Take a look at our range of gas generators! All three of our on-site generators are available in multiple models with different flow rates and dimensions so you can match the system to your application. We understand how important it is to select the right nitrogen generator for your production processes, and our Ingersoll Rand specialists are ready to help you make the right choice. Our oxygen generator options follow the same approach, offering a range of capacities and purities for industries that depend on a steady, on-demand oxygen supply. Together, our nitrogen and oxygen portfolios give you flexible, reliable paths to onsite gas generation, supported by experts who know how to align the right model with your goals.

HS Series On-Site Nitrogen Generators

Maximize the productivity of your operations with our high-quality HS Series on-site nitrogen generators. Built for reliable performance and efficiency, these solutions generate nitrogen from freely available air, removing any need for traditional nitrogen delivery methods. Nitrogen production can be adapted to meet you exact application needs, even in times of fluctuation or demand changes, as these on-site generators are capable of purity levels ranging from 95% to 99.999%. By also considering our range of complementary products designed specifically to suit these generators, you can create a nitrogen production process you can trust from start to finish!

Using high-quality, synthetic coolant can extend the compressor’s lifespan and keep the system operating at peak performance. The Coolant Lubricant line from Ingersoll Rand offers high thermal conductivity to withstand extremely high temperatures.

In order to know the best lubricant to match your air compressor, you should take into consideration:

  • Technology: Ingersoll Rand offers various lubricant lines for small reciprocating air compressors, rotary screw air compressors & oil-free centrifugal air compressors.
  • Application: Ingersoll Rand offers lubricants that are specifically designed for demanding applications, such as ones in the Food & Beverage industry where avoiding contamination is important.
  • Operating needs: Ingersoll Rand offers the best lubricant options to match your operating needs. We have lubricants that are most suitable for primary air compressors running for many hours a day. We also offer special lubricants for back-up units that do not run only when needed. Back-up compressors may have less extensive lubrication needs because they are small, or used less often. Taking your operating needs into consideration is key to avoid overspending.
