About GT GasTech
GT GasTech GmbH is a medium-sized company based in Witten on the Ruhr that manufactures, fills and delivers medical gases, technical gases and CO2 carbonic acid nationwide. Its core business lies in the manufacture, filling and patient supply of medical oxygen in all delivery forms – including compressed gas cylinders (GOX), liquid oxygen (LOX), stationary and mobile O2 concentrators, and oxygen filling systems. In addition, the portfolio includes medical compressed air, nitrous oxide and medical carbon dioxide, as well as technical gases such as argon, nitrogen, helium, acetylene and welding shielding gases in standard cylinder sizes with accessories and fittings. Filling takes place in a state-of-the-art plant with PLC-controlled filling technology for aluminium and light steel cylinders. Carbonic acid compliant with E290 is filled in sizes from 425 g to 10 kg, among other things for water carbonators, gastronomy and aquaristics, since 2022 under the GOOD LIFE SODA brand. Supply to hospitals, medical supply stores, emergency services, homecare sectors and specialist retailers is carried out with an own vehicle fleet; a cylinder exchange system complements the offering.
