A History of Business Success

Over the past 25 years BAPI has forged a place in the HVAC/R industry, with our area of expertise focused on advanced sensor technology for HVAC & R applications. Originating in Cross Plains, WI in 1993, BAPI’s first facility was literally conducted out of a small two-car garage. Today, we serve customers around the globe from a 52,000 sq foot facility based in rural southwestern Wisconsin. BAPI continues the “…it’s in the details” tradition, using the highest quality sensing elements paired with state of the art manufacturing, meticulous testing and quality assurance procedures to ensure a reliable product time after time.
