Founded in the 1950s as Tanzania Oxygen Limited, the company has evolved into the absolute dominant manufacturer and distributor of industrial and medical gases in East Africa. The company operates massive, technologically advanced air separation units and carbon dioxide extraction plants in Dar es Salaam, Mwanza, and the Kyejo natural gas wells.
