Deppmann - A Rich History
Deppmann was started in Detroit, Michigan in 1927 by Raymond L. Deppmann. In 1929, RLD became one of the very first Bell and Gossett representatives.

Note: Bell and Gossett celebrates its 100th year in 2016 and Deppmann has been a trusted partner for most of that time.
Ray Deppmann and his team believed the company could be more than just another supplier. He believed the company could help his customers make better decisions in the fledgling hydronic heating industry. Ray hired registered engineers, contractors, and wholesaler leaders to build a team of experts that no other supplier had.
Today, Deppmann continues the tradition started by Ray Deppmann. Many of our sales reps are graduate engineers and all of our sales staff graduate from rigorous factory training programs.
