Nitrogen generator rental for critical operations worldwide

Oil & Gas Shutdowns — Fast-mobilised nitrogen for pipeline purging, vessel inerting, and turnaround schedules where LIN logistics fail.

Coal Mining — Fire suppression, goaf inertisation, and underground safety. Skid and underground-rated units engineered for remote-site rental.

Food & Beverage — Modified atmosphere packaging, bottling, and cold-chain blanketing. Rental lets you scale with seasonal demand.

What is nitrogen generator rental? Oxair nitrogen generator rental puts a self-contained membrane nitrogen plant on your site — skid-mounted for surface operations or ATEX-rated for underground mines. You get continuous nitrogen at 95% to 99.5% purity, produced from compressed air, for as long as the job runs. No tanker schedules. No cylinder swaps. No pressure-test delays because a delivery missed the gate. Membrane technology has no cycling valves in the separation stage — it is vibration-tolerant, fast to start, and mobile-ready, which makes it ideal for rental deployments in remote sites, turnarounds and tropical climates. Skid rental suits oil & gas turnarounds, food & beverage packaging, and industrial inerting. Underground rental is engineered for coal mining fire suppression, goaf inertisation, and sealed-panel safety. Both ship ready to commission — engineered in Perth, field-proven in Australia's harsh mining and oil & gas environments, and deployed across APAC, Africa and the Middle East. Backed by 36 years of gas separation experience and 600+ installs worldwide. For 99.99%+ applications we offer PSA units on request.

Why rent a nitrogen generator over delivered LIN or cylinders? Nitrogen generator rental typically runs at 50%+ lower cost per Nm³ than delivered liquid nitrogen (LIN), removes tanker-schedule risk from shutdown and turnaround timelines, and eliminates the cryogenic exposure of on-site liquid storage. On-site membrane nitrogen also cuts embodied CO₂ compared to LIN — no road transport, no refrigeration, and no evaporation losses on site.

Our nitrogen generator rental fleet — flow rate, purity and tier guidance. Four tonnage tiers cover everything from pilot lines and packaging (50 Nm³/hr) to refinery-scale inertisation (2,000+ Nm³/hr). Every tier runs the same membrane separation architecture with no cycling valves, vibration-tolerant manifolds, and remote PLC monitoring for operator visibility and service scheduling.

Oxair rental skids — tonnage tiers

All skids are containerised, AU-engineered to ISO 9001, and delivered ready to commission. Custom configurations available.

Tier 1

Compact

50 – 200 Nm³/hr

  • Purities 95% – 99.5% (membrane)
  • 20-ft containerised
  • Food packaging, wineries, lab use
Tier 3

Heavy-duty

500 – 1,000 Nm³/hr

  • Purities 95% – 99.5% (membrane)
  • 40-ft containerised, redundant train option
  • Shutdowns, mining, pipeline purging
Tier 4

Tonnage

1,000 – 2,000+ Nm³/hr

  • Purities 95% – 99.5% (membrane)
  • Multi-skid, site-engineered
  • Major shutdowns, continuous inerting
Standard units are road-transportable from Perth and sea-freighted to APAC, Africa and the Middle East. Heavy-duty (Tier 3) and tonnage (Tier 4) skids can be arranged as multi-skid arrays where a single unit would not meet demand.

Proven in harsh environments, deployed worldwide. "Portable skid units mean clients don't need expensive surface drilling or kilometres of underground piping. We deliver nitrogen where it's needed, when it's needed — and it's fundamentally safer for crews working in confined or sealed areas." — David Cheeseman, Oxair. Oxair rental skids have supported oil & gas operators, coal mining fire-suppression programs, and food & beverage plant upgrades across Australia, APAC, Africa and the Middle East. Our fleet is engineered in Perth and field-tested in Australia's harsh mining and oil & gas environments — then mobilised globally. With 36 years of gas separation experience across membrane and PSA systems, ISO 9001 certification, and 600+ installs worldwide, our rental fleet is engineered, commissioned, and serviced by the same team that builds the systems.

Frequently asked questions

What is a nitrogen generator rental and how does it work?
A nitrogen generator rental is a skid-mounted membrane nitrogen generator that produces high-purity nitrogen on-site from compressed air. Oxair delivers the skid to your site, commissions it, and you pay a monthly rental covering the equipment — you only pay for electricity to run it. When the project ends, we demobilise. No capital outlay, no long delivery contracts. Membrane technology has no cycling valves, is vibration-tolerant, and is purpose-suited to mobile and shutdown work. See also our nitrogen membrane technology page.
Why membrane technology for rental instead of PSA?
Membrane nitrogen generators are the right tech for rental because they have no moving parts in the separation stage, no pressure-swing cycling, and no carbon molecular sieve that can be damaged by vibration or humidity. That makes them faster to start up, simpler to maintain in remote locations, and robust on trucks, barges, and shutdown sites. PSA is better suited to fixed installations at 99.99%+ purity — if your application requires that, we can supply a PSA unit on request.
How much does nitrogen rental cost compared to delivered liquid nitrogen (LIN)?
For continuous operations above ~100 Nm³/hr, on-site rental typically delivers 30–60% savings versus delivered LIN, depending on flow rate, usage hours, and local electricity price. Use the ROI calculator on this page for a site-specific estimate, then request a personalised quote for exact rental pricing and payback.
What flow rates and purities do Oxair rental skids support?
Oxair rental skids cover 50 Nm³/hr through 2,000+ Nm³/hr across four tonnage tiers. Membrane units deliver purities from 95% (inerting, purging, mining inertisation) through 99% (shutdowns, blanketing, food & beverage) and up to 99.5% (high-purity packaging). For 99.99%+ applications we offer PSA units on request. Higher purity requires a larger unit or slower production rate for the same flow.
How quickly can Oxair deliver and commission a rental skid in Australia?
Lead times for standard configurations are typically 2–6 weeks from order, including transport to site. Oxair is headquartered in Perth, WA, and services all Australian states and remote sites. For shutdown-critical timing, contact us early so we can pre-stage equipment.
Are Oxair rental skids suitable for oil and gas shutdowns?
Yes. Skid-mounted nitrogen rental is one of the most common applications. Skids are containerised for rapid deployment, produce nitrogen on-site for tank purging, line inerting, and pressure testing, and eliminate the logistics and safety risks of bringing large volumes of LIN to site during shutdowns.
Can I use a nitrogen rental skid for coal mining and underground applications?
Yes. Oxair has a dedicated underground rental solution and a portable skid variant suited to surface coal mining — used for fire suppression, inerting, and goaf sealing. See the underground nitrogen generator rental article for the mining-specific case.
What electricity and compressed air supply does a rental skid need?
Oxair skids are designed to plug into standard site three-phase power. The skid includes the PSA train; an integrated compressor option is available, or you can supply compressed air from your own utility. For membrane systems, typical specific energy ranges from ~0.40 kWh/Nm³ at 95% purity up to ~1.6 kWh/Nm³ at 99.5% — the energy penalty climbs steeply at higher purities, which is why PSA is preferred above 99.5%.
How does the rental skid compare to cylinder nitrogen supply?
For any site using more than a few hundred kilograms of nitrogen per month, cylinders become more expensive than rental skids on a per-Nm³ basis, and they introduce handling, swap-out, and runout risk. Rental skids are the clear winner for continuous or medium-volume use.
Does Oxair manufacture the skids in Australia?
Yes. Oxair designs and manufactures membrane and PSA nitrogen systems in Perth, Western Australia, to ISO 9001 quality standards, with 36+ years of experience and 600+ installations globally. AU-engineered equipment means faster service response, local parts, and compliance with Australian standards.
What maintenance and servicing is included in the rental?
Scheduled preventive maintenance and remote monitoring are included. Membrane modules have no moving parts and minimal wear — the primary maintenance items are air filters, coalescer elements, and compressor service. Oxair includes scheduled preventive maintenance and remote monitoring for the rental term. On-call technical support is included for the rental term.
