Zehnder-Rittling is a combination of two family owned business, both with a very interesting history.
Jakob Zehnder first went into business in 1895 as a mechanic and bicycle dealer. The business evolved in the 1920’s, the Zehnder family began to successfully manufacture the Zehnder light motorcycle. It wasn’t until 1930 that they invented the product that would lay the foundation for the company’s future success: Europe’s first steel tube radiator.
The Rittling Corporation was founded by Charles Rittling in 1946. Their initial business was started by producing hydronic unit heaters in Buffalo, NY. As market demand in the U.S. changed, the company shifted its focus to commercial and residential heating needs that could be utilized with the new energy infrastructure developed in the 1940’s – 1950’s. Rittling was awarded its first US patent for twin tube residential baseboard elements in 1953. Hydro-Air Components acquired the Rittling Corporation and added Rittling Finned Tube to the product offering in 1979.
