About Carbagas
CARBAGAS AG, headquartered in Gümligen, is a Swiss supplier of gases for industry, medicine, trades and research. Founded in 1893 as "Kohlensäurefabrik Bern A.-G.", the company belongs to the Air Liquide Group and supplies around 53'000 customers in Switzerland. The portfolio includes cylinder gases, tank gases, cryogenically liquefied gases, high-purity and specialty gases, custom gas mixtures and dry ice. Products manufactured, filled and distributed include oxygen, nitrogen, argon, carbon dioxide, hydrogen, helium, acetylene and shielding gases for welding and cutting. With onsite gas generation systems, liquid nitrogen supply (LIN), 30 km of pipeline, 70 sales outlets and a digital customer portal, Carbagas covers the entire gas supply process chain – from consulting and calibration standards to container monitoring. Distribution takes place in Switzerland.
