Additive Systems Inc., ASI, was started in 1984 by people experienced in the refined products industry. We identified problems with delivery complexity, changing technology, inexperienced technicians and increasing governmental regulations. The answer was obvious: improve cost efficiency by providing the best trained technicians, high quality products, superior planned maintenance and precision data control systems.

For nearly 15 years, before starting ASI, R.N. "Bob" Roggendorff worked for a major oil company (his last ten years were spent as terminal manager of a fuels tank farm and truck loading facility). This invaluable "hands-on" experience coupled with dedicated employees and a "can do" attitude quickly established ASI as a dominant player in the liquid terminaling industry. Three (3) short years after starting ASI in a shop behind his home, it was obvious to the ASI team (9 employees by 1987) they needed a new home.

Today, ASI operates two separate facilities. The main office is still located in ASI's hometown of Broken Arrow, Oklahoma and the other in Dallas, Texas.

ASI has created an environment that includes the most proficient and experienced people in the industry. Currently our team consists of approximately 20+ employees and 250+ years of combined experience. This includes electrical, mechanical, computerization, custom fabrication, welding, engineering, or any of today's high-tech needs, as well as having the knowledge and expertise to work with products that revolutionized the market almost thirty years ago.

ASI is a single source provider that takes the headaches out of the downtime problem. We offer the equipment, troubleshooting expertise and maintenance services to keep liquid products flowing with better control and fewer problems.

Downtime is every company's nightmare. When things go wrong, rapid response is critical to the bottom line. Preventive maintenance is one of the best solutions. Quality products is another. Having both works best only when there is someone to call who knows the business. So, call ASI first.
