What’s our big R&D Secret?

Long-term commitment. Consistent leadership.


On Site Gas Research and Development On Site Gas has always been a leader. To make sure we’re not only staying ahead of the curve, but also defining it, we decided long ago to dedicate a substantial portion of our resources to research and development. We bring an extraordinary depth of experience to bear; in fact, many of those involved in R&D at On Site have been with the company for decades.

Our Founder and President, Francis X. Hursey is a veteran of the Apollo Breathing Air Team and has been awarded multiple patents in Noncryogenic gas technology, Medical Products and Nitrogen applications.  He invented QuikClot® brand hemostatic agent and was recognized as a top scientist in 2003 by Scientific American.

 

Our philosophy is to keep the simple processes simple, and make complex processes less complex. This way of thinking has formed the basis for our growth, and has steeled our product reputation. We use COTS (commercial off-the-shelf) parts so that our systems can be serviced by a mechanically inclined person, anywhere in the world. We have worked with and tested all technologies involving PSA gas production, and continue to find that our technology, improved over time, makes the most reliable systems in the world. We constantly seek new ways to apply our proven technology.

R&D In Action: Portable Systems
We’re not called On Site for nothing. While many of our systems have a dedicated location in a physical plant, many of our customers need gas systems on demand — ready wherever and whenever. Our engineers went to work, and the result is portable systems that range from small, self-contained units like POGS (Portable Oxygen Generating System, used as emergency medical oxygen by the military, first responders, and disaster management teams) to large, nitrogen-generating trailer systems that can scramble to a remote mine location in a matter of hours. Flexibility and dependability are two hallmarks of On Site R&D.

R&D In Action: Tire Filling
Once, compressed air was the gas of choice for inflating tires. But NASCAR, airplanes and energy conscious companies use nitrogen. There are many benefits to using nitrogen for tire inflation. Nitrogen eliminates oxidation and offers better tire pressure retention. The bottom line? A safer, smoother ride, improved fuel economy, and prolonged tire life. Over a decade ago, we introduced the On Site Gas nitrogen tire inflation system. Our PSA systems provide yearly, consistent nitrogen supplies; work in tough environments and ever-changing conditions; and offer a low operating capacity-to-cost ratios.

R&D In Action: Multiple Purities - One System
Many of our customers have the need for more than one purity of oxygen or nitrogen.  On Site's solution is a purity flow exchange (PFX) design rather than selling a higher purity machine than is required.   This allows the customer to change between purities as their process demands. We offer up to three different purities on one machine - another way we lower your costs.
