Our specialty gas plant in Decatur, Ill., provides customers with the highest quality, pure, mixed and custom-blended gases available.

Bulk and Micro-Bulk Options

When your gas usage increases to a point where high pressure or liquid cylinder solutions won’t meet your needs, S.J. Smith offers micro-bulk systems that mount permanently in small spaces.

Micro-bulk gas supply is a great way to eliminate time spent changing cylinders, managing deliveries and handling liquid cans. Another option is to install an outdoor bulk tank system at your facility, freeing up space indoors, and ensuring your gas supply is always available. With the resources of S.J. Smith and our partnership with the world’s largest gas producers, we are a primary bulk gas provider in Illinois, Iowa and northeast Missouri. S.J. Smith can install and fill liquid nitrogen (LIN), liquid oxygen (LOX) and liquid argon (LAR) bulk tanks of 300 gallons and up.

If you are changing your gas usage, or have increased usage due to new equipment, call us at 563-324-5237, or talk to your account manager today. We have the solution you’re looking for.

"I've been a customer at SJ Smith in Decatur for 10 years now, and every time I stop by, the guys there are so incredibly friendly and helpful. From refilling my oxy/propane mini tanks for metalsmithing work to swapping out my propane tank on my grill, they've always helped me with everything I've needed. When I first started out with a torch, one of the guys even helped me figure out how to disassemble and reassemble my torch and gauges to my tanks safely. Its always a pleasure to swing by."
