On-Site Oxygen for Landfill Gas & Agricultural Biogas Projects
Landfill gas projects, farm digesters, and wastewater treatment biogas systems share the same H₂S problem — and the same logistics challenge: they're often far from oxygen suppliers. ON2 containerized plants generate the oxygen on-site, outdoors, year-round.
Made for remote and rural sites
ON2's containerized format was engineered for exactly these conditions — the ROCS line stands for Remote Oxygen Concentrator System. The plant ships as a complete unit, sits outdoors in any climate from −50°C to +50°C, and runs on demand without operators standing by. ON2 has been building oxygen systems since 1984 for sites where delivered oxygen isn't practical.
Follows variable gas production
Landfill and agricultural gas flows vary with feedstock, weather, and season, so oxygen demand varies too. Because the plant produces on demand and goes to standby when it isn't needed, the oxygen supply tracks your gas production instead of running continuously regardless of need.
Specifications that match biogas requirements
ON2 containerized oxygen plants deliver 90–95% oxygen purity — the range typically specified for biological desulfurization — with delivery pressure adjustable from 0 to 50 psi to match your digester headspace or injection point. The insulated, climate-controlled container is engineered for year-round outdoor operation from −50°C to +50°C, proven in deployments from Yellowknife, Canada to New Delhi, India.
Buy it or lease-to-own
ON2 offers direct purchase or lease-to-own over 5 or 7 years, so the oxygen plant can be matched to your project's capital plan instead of the other way around. Either way you deal with a single manufacturer — we understand your project, design the system, then build, ship, and commission it. ON2 has been building oxygen systems since 1984, with systems made in Canada and the US.

Frequently asked questions
Do these plants work at remote sites without full-time operators?
Yes. The plant is a self-contained, climate-controlled container designed for unattended outdoor operation. It produces oxygen on demand and stands by when the process doesn't need it.
Can the plant sit outdoors year-round?
Yes. The insulated, climate-controlled container is engineered for year-round outdoor operation from −50°C to +50°C, proven in deployments from northern Canada to India. It arrives as a complete plug-and-play plant — no building required.
Can the delivery pressure be adjusted to our injection point?
Yes. Delivery pressure is adjustable from 0 to 50 psi, which covers typical digester headspace injection requirements — including low-pressure headspaces maintained at only a few millibar where outlet pressure requirements sit in the low-psig range.
Can we lease the oxygen plant instead of buying it?
Yes. ON2 offers lease-to-own over 5 or 7 years alongside direct purchase, so you can spread the cost into predictable payments and keep capital available for the rest of the project.
