Proton OnSite manufactures hydrogen, nitrogen, and zero air generators that you can rely on. Our on-site gas generators provide a safe, reliable, and cost effective way for our customers to get the gas they need, when and where they need it.

Our commercial equipment is operating on every continent, from the middle of the desert and the depths of the sea, to the most prestigious laboratories in the world. No other company has as large of a commercial fleet, or as long of a recorded history with reliability as Proton OnSite.

We are exclusively focused on customer solutions, and have the experience and products to assure success.

Proton OnSite is a global leader in hydrogen energy and innovative gas solutions. Since 1996, we have been developing and applying hydrogen technology in creative and practical ways that best meets the diverse requirements of our customers.  Our advanced proton exchange membrane (PEM) electrolysis systems coupled with our uncompromising attention to excellence and quality enables us to deliver, install and support gas generation units on every continent.

More recently, we have expanded our product offerings to include hydrogen control systems, nitrogen generators and air generators. We have also expanded our services to include packaged solutions incorporating tanks, compressors and other ancillary equipment. These products and services now allow us to serve a broader commercial set of markets including power plants, semiconductor manufacturers and laboratories.

Proton OnSite is a trusted partner to the U.S. military, aerospace, fueling and renewable energy industries because at Proton, we understand that the current energy market demands leadership, expertise and innovation. We are also at the forefront of the clean energy industry, committed to developing superior energy solutions that provide the most value to our partners throughout the globe.

Because we have continued to grow and develop beyond the expectations of Proton Energy Systems, we have decided to change our name and logo to best address our diversity of markets and reflect the growing array of commercial products and services that we offer beyond hydrogen generation - Proton OnSite is now THE leader in on site gas generation.

Our name has changed but the company behind the name remains the same. Our dedication to quality products and services is unwavering and as such, we invite you to put the same trust in us as you have done for the last 15 years in hydrogen generation for all of your other on site gas needs.
