Our history dates back to the 1930's as the medical department of National Cylinder Gas (NCG) in Chicago. NCG produced gases in cylinders and sold them to hospitals in the 1930's and early 1940's. These cylinders had to be carted around from floor to floor when and where needed. In order to eliminate the use of the heavy cylinders, the cost of moving them around, and the explosive hazards of handling them, the idea was developed to pipe medical gases from an outside source to the point of use, either at bedside or in the operating room. Thus the innovative Chemetron® medical gas piping system was developed and the Chemetron Medical Products Division of National Cylinder Gas was formed in 1947. The Chemetron Medical Products Division became the pioneer of piped medical gases and vacuums to hospitals and dental clinics, and soon had piped more facilities than all other companies combined. It also created new healthcare equipment that became the standard that other companies strove for, no longer restricted to the respiratory field.
