Cylinder Filling Plants


The OGSI MOGS 50/100 Medical Oxygen Generating System has been designed to produce oxygen onsite and fill high pressure cylinders (up to 2200 psi) or to supply oxygen directly at up to 70 psi. This system uses oil-free air compressors and modular oxygen generators for redundancy and reliability. The system produces Medical Grade Oxygen in accordance with the US Pharmacopeia specifications. There is a continuous gas quality monitoring system included with automatic shutdown if a fault occurs.

Larger CFP's (8-180 cylinders/day)

If you are in an area poorly served (unreliable oxygen supply and/or high prices) by the traditional gas companies, you can fill your own oxygen cylinders.

OGSI offers a complete line of cylinder filling plants (CFP's). These plants can be designed to produce oxygen up to 95% purity for most oxygen applications, including breathable hospital requirements. The oxygen purity from OGSI plants is typically at 93% (+/- 3%), with the balance being even amounts of nitrogen & argon. OGSI equipment is fabricated in accordance with all relevant codes (ASME, ANSI, NEMA, CE) and can be configured to meet CRN and CSA Standards. Oxygen produced meets the United States Pharmacopeia (USP) XXII Oxygen 93% Monograph as well as European and other Pharmacopeia.

OGSI CFP's include all the support equipment required such as air compressors, air dryers and oxygen compressors for complete turnkey systems. All models are factory tested, and most are skid mounted.

Complete CFP's, capable of filling 8 to 180 cylinders per day are currently available in standard sizes. The plant size is based on the number of high pressure, 6m3 size (aka. K or H-size) oxygen cylinders the plant can fill in 24 hours. Listed below is a quick reference on the model and size of the plants we offer. Please contact us about custom sizes available too.

Model CFP-100 8 cyl's/day
Model CFP-175 10 cyl's/day
Model CFP-250 20 cyl's/day
Model CFP-500 50 cyl's/day
Model CFP-650 60 cyl's/day
Model CFP-1000 100 cyl's/day
Model CFP-1250 120 cyl's/day
Model CFP-1800 180 cyl's/day

These plants are designed to be shipped in standard 20 or 40-foot ocean containers for worldwide transit. On-site commissioning & training is available from an OGSI  technician. Electrical power and an enclosure for the plant are all that is required at the customer's site to get started.
