Slovenija | Messer has installed an oxygen production unit in Hrastnik for the glass manufacturer Steklarna Hrastnik. The company has been using oxygen to melt glass for more than 50 years now. Previously, the gas has been delivered in tank cars. The new on-site unit will reduce transport costs significantly while raising supply reliability at the same time. The use of oxygen increases the efficiency of combustion in the melting furnace and, thus, reduces CO₂ emissions.
