R. L. Deppmann—Serving the Greater Detroit Area Since 1927
Raymond L. Deppmann opened the Detroit office in 1927 as a distributor of oil burners. In 1929 R. L. Deppmann became the first or second stocking representative of Bell and Gossett pumps. Folklore has it that Ray was not the first representative because he held the door open for an equally able friend from another state.
In the 1950s and 1960s, hydronic heating flourished and engineers turned away from steam for the comfort and zone control offered by this continually growing HVAC option. R. L. Deppmann became a controls leader with Barber Colman. Deppmann was a control company that dabbled in hydronics. In the late 1960s, Ray dropped the Barber Colman line and concentrated on hydronics and Bell and Gossett.
As the company grew the Detroit location changed to warehouses on West Baltimore, John Lodge Freeway, Bridge Street in Southfield for 38 years, and a final move to Novi, Michigan.
In 1971 ten key employees purchased the Company from Ray Deppmann. The new management team was led by Zaven Margossian, Robert Whymer, Art Turner and Andy Sturgeon.
In 1991, the third management team was elected to move the employee owned (ESOP) Company into the future. We turn to our roots and continue the dream of Ray Deppmann with our training and support segments of E3 (engineering specifiers, end user specifiers, and Corporate education) and estimating segments.
Much of Ray Deppmann’s wealth was attributed to his real estate investments in Saline, Michigan. Today if you look at a map northwest of Saline, you will still find Lake Deppmann.
