CATCO Catalytic Heater Company was founded in 1982 by Bill Richards. Equipped with a degree in petroleum engineering from Texas A&M, Bill spent his career in the oilfields, retiring from Teledyne-Merla as VP Sales in 1980. After hearing from colleagues that the lead time for catalytic heaters was causing problems, he decided to fulfill his lifelong dream of owning his own business. Bill’s new company started small, first opening in a closet that housed parts behind his son’s tractor dealership. But Bill had a clear vision and a strategy crafted by carefully observing where competitors fell short. His primary goal was to build CATCO into a company that is easy to do business with—one that puts problem-solving and customer service first. That continues to be the company’s driving philosophy. Catalytic heaters, which are currently the company’s single product line, go hand-in-hand with that philosophy; they are a simple, straightforward solution to common problems in the natural gas industry. That philosophy is embodied in the driving statement: The CATCO Way.
