About A.C. Bach GbR
A.C. Bach GbR is a Stuttgart-based company founded in 1973 that specializes in plant engineering for ultrapure media, vacuum and cryogenics. Its range of services includes needs analyses, project engineering, development, CAD design, and the implementation of supply systems for bulk gases, cryogenic and liquefied gases (LN2, LO2), specialty and ultrapure gases with manual to automatic control, as well as building and equipment vacuum. Products manufactured include piping systems, supply stations such as cylinder stations and extraction points, recleaning systems, gas detection and monitoring systems, disposal systems (scrubbers), as well as helium recovery systems and liquefiers. Pre-assembly is carried out in the company's own Class 100 cleanroom. Materials processed include copper and stainless steel in various grades of purity, including specially cleaned, polished and electropolished, as well as VAR and VIM/VAR stainless steel. Customers come from industries such as microelectronics, pharmaceuticals, medical technology, laboratory and environmental analysis, and plant engineering; the company has been qualified to ISO 9001 since 1999.
