RENK Group, a leading manufacturer of mission-critical drive technologies, is supplying three high-speed special gear units via RENK-Maag GmbH, a group company, for compressors for the production of green steel to Siemens Energy Compressors GmbH as part of the “SALCOS” (Salzgitter Low CO2 Steelmaking) project of the Salzgitter AG steel group.
Nadine Despineux, CEO of RENK’s Marine & Industry Division, commented: “We are very pleased to be part of this beacon project for green steel in Germany. With our innovative gearbox solutions for the compression of hydrogen, we regularly push the limits of what is technologically feasible with incredibly high speeds. This way, we are already helping to reduce CO2 emissions in steel production by around 30 per cent. Water is then produced instead of CO2. This way, we support our customers significantly on their way from fossil energies to climate neutrality. And we see great growth potential, because the entire industry is currently converting its production processes.”
Clemens Förster, Sales Manager of Siemens Energy Compressors GmbH, said: “With our technology, our customers are able to switch to hydrogen-rich reduction gas without structural changes to the integral gear compressors. As the name suggests, the gearbox is an integral part of this. We are glad to have RENK-Maag as a strong partner at our side. With this beacon project, we are supporting our industrial customers on their way to decarbonization and are thus an important building block for the steel industry to achieve its CO2 reduction targets.”
Thomas Fritschi, Managing Director of RENK-Maag in Winterthur, added: “Our high-speed gear units for compressors are an important component for the ramp-up of the hydrogen economy – whether for storage, processing or transport. These turbo compressors are characterized by a high pressure build-up and are suitable for large gas volumes. Specifically, we are talking about gear units with a speed of 8,000 to 50,000 revolutions per minute – but we have also produced units with a speed of over 60,000 revolutions per minute. Just for comparison, the engine speed of a passenger car in normal driving is a maximum of 2,000 to 3,000 revolutions per minute.”
RENK Group is supplying three high-speed special gear units to Siemens Energy Compressors GmbH for the “SALCOS” (Salzgitter Low CO2 Steelmaking) project of the Salzgitter AG steel group. The gear units, developed and built at the RENK site in Winterthur, Switzerland, are used in a direct reduction plant in Siemens compressors and are capable of speeds of 8,000 to 50,000 revolutions per minute.
