Erie Technical Systems grew from founder Rick Sienerth’s garage start-up in 2001 into an Erie, Pennsylvania manufacturer with a 50,000-square-foot facility. Sienerth launched the company after earning patents for FIBC filling machines and processes, later partnering with chemical engineer Tim Porco to deepen its automation expertise. Today, the company develops custom equipment for handling dry solids in industries such as chemicals, food, mining, and plastics.
