It was the race to the moon. The Apollo Program. And Francis X. Hursey was pioneering PSA (pressure swing adsorption) oxygen technology as a member of the spacecraft’s breathing air team. After Project Apollo, Frank helped develop one of the first oxygen concentrators for home use. It was this core of knowledge that led him to found On Site Gas Systems in 1987.
So, who is On Site Gas? As you might have guessed from our name, we design and build gas-generating (oxygen and nitrogen) systems that function on-site at your physical plant. Our systems are used in mission-critical applications, across dozens of industries, in over 70 countries. Although we often create highly customized designs, all our systems are built in the USA with common, readily available COTS (commercial off-the-shelf) parts. In our 20 years of business, we have exhibited an unprecedented level of growth and excellence — in fact, we’ve now made the Deloitte “Fast 50” for 7 years in a row. Our customers use On Site Gas Systems to replace or augment other gas delivery methods, and many report monthly savings of up to 80%. How can we help you today?
We are a private, self-funded company with over 40 employees, many of whom hold at least one patent. In a nutshell, On Site Gas Systems does just what our name implies: we design and build PSA and membrane oxygen and nitrogen generation systems that function “on-site” — wherever that may be. Our safe, continuous, flexible systems provide cost-saving, reliable gas generation for numerous applications, and can be found in over 70 countries. We are a unique company of product development engineers, and On Site is considered by many to be the gold standard for PSA technology. We are the only non-cryogenic company in the world that offers membrane, PSA Nitrogen systems (95-99.9995% purity), and PSA Oxygen (USP 93-99% purity) systems for both medical and industrial use. We are the only industrial gas generation company with FDA approval for our military medical O2 systems — and all of our PSA and membrane systems meet or exceed USP standards for food grade and medical N2 and O2.
