In 1963, DeLille Oxygen Company was purchased by the current Smith family that still owns and operates the company. That same year DeLille had a Rexarc Acetylene generating plant built that produced Acetylene from Carbide.
The Acetylene plant was an introductory to gas manufacturing for DeLille as well as the importance of manufacturing independence. Although numerously updated, the same Acetylene plant from 1963 is still in operation to this day at the Columbus, Ohio, DeLille location.
