In the cooling systems industry, the Roppel family of Kentucky is well known. In this episode of “Solder & Soot,” we sit down with father and son Tom and Corey Roppel to learn about the early days of the family business and how Roppel Industries has transformed over the past 75 years. This episode isn’t strictly all business, though. We also talk about Kentucky bourbon, learn about Tom’s best pranks, and hear why the Roppels refuse to wear socks.
