On-Site Oxygen for Biogas & RNG Plants in Minnesota
Minnesota's mix of dairy farms, livestock operations, and agricultural processing supports digesters across the state — corn-belt sites where H₂S control decides how long engines and upgrading equipment last. ON2 supplies the oxygen for biological H₂S desulfurization as a complete containerized plant — designed, built, shipped, and commissioned by one US manufacturer, generating oxygen on your site from ambient air.
Northern-winter rated for Minnesota digester sites
Minnesota winters are well inside the design envelope: the insulated, climate-controlled ON2 container is engineered for year-round outdoor operation down to −50°C, proven in deployments as far north as Yellowknife, Canada — so no heated building has to be built around the oxygen supply. The plant generates oxygen on demand from ambient air for biological H₂S removal, follows variable gas production by standing by when oxygen isn't needed, and arrives as a complete plug-and-play unit that ON2 ships and commissions at your site.
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.
Patented vacuum-cycle technology
Every 100 seconds, a vacuum sweep purges heat, humidity, and contaminants out of the system — no external air dryers and no sieve degradation. The plant runs on demand: it produces oxygen when your process needs it and goes to standby when it doesn't, unlike conventional PSA generators that typically run continuously whether oxygen is needed or not. The technology is patented, with additional patents pending.
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 every system manufactured in the USA.

Frequently asked questions
Does ON2 supply oxygen plants to biogas projects in Minnesota?
Yes. ON2 designs and manufactures containerized on-site oxygen plants in the USA and ships and commissions them anywhere in Minnesota — the plant arrives plug-and-play and sits outdoors year-round, so no building is required at the site.
What oxygen purity do ON2 plants deliver for biogas desulfurization?
ON2 containerized oxygen plants deliver 90–95% oxygen purity, the range typically specified for biological hydrogen sulfide removal in anaerobic digesters. Purity and flow are confirmed against your gas volume and composition during quoting.
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 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.
