What On Site Gas Systems does
On Site Gas Systems, Inc. is a privately held U.S. manufacturer of on-site nitrogen and oxygen generation systems, founded in 1987 and headquartered in Newington, Connecticut. The company designs and builds capital equipment based on two core technologies: Pressure Swing Adsorption (PSA), which uses carbon molecular sieve (CMS) to separate nitrogen from compressed air at purities up to 99.9995%, and polymeric hollow-fiber membrane separation, which produces nitrogen at 95%–99.5% purity. Product lines span PSA and membrane nitrogen generators, custom-engineered systems, ISO containerized units (10/20/40-foot) with flows up to 90,000 SCFH, the Nitro-Blast beverage infusion system, nitrogen and oxygen cylinder filling stations, PSA oxygen generators (up to 95% and 95%–99% purity), and the FDA-approved Portable Oxygen Generation System (POGS). All manufacturing is performed in two ISO 9001:2015 and ISO 13485:2016 certified Connecticut factories.
The company sells primarily through a direct enterprise field-sales motion — web quote requests, phone sales, and project-engineering consultation — targeting industrial, commercial, medical, and government/military end markets including oil & gas, mining, food & beverage, electronics manufacturing, chemicals & plastics, metal/heat treating, healthcare, and defense. Revenue is generated predominantly through one-time capital equipment sales (with ROI typically achieved in under 18 months and 80% cost savings versus delivered gas), supplemented by emergency short- and long-term generator rentals via a field services division and ongoing service, parts, and training revenue. A Remote Monitoring add-on service and a 24-hour emergency POGS support line extend the relationship into recurring and managed-service revenue. Thousands of systems are deployed across 100+ countries, with named customers including Intel, Exxon, Coors, FritoLay, Johnson & Johnson, Honeywell, Toyota, Tiffany & Co., Starbucks, Kraft, Unilever, Firestone, National Geographic, AT&T, and the U.S. Army.
