Protanic

Established in 1972, Protanic began by pioneering petroleum leak detection at service stations. Co-founded by engineers William Purpora and Dave Beets, the company's journey shaped the industry. In the 70s, the industry lacked any regulations or protocols governing tank and line leak detection, yet William’s relentless drive for proper leak detection methods and training set the groundwork for Protanic's success. In June 2021, Stenstrom Petroleum Services Group acquired Protanic and Purpora Engineering, marking a new chapter for the company. As part of the Stenstrom petroleum family of businesses, Protanic proudly serves as its compliance division. With a well-established reputation as a market leader in fueling system service, repair, and construction across Illinois, Wisconsin, and Iowa, Stenstrom Petroleum caters to industrial, commercial, and retail sectors.
