The company penstocks.de GmbH, situated in the Federal Land of Baden-Württemberg in Southern Germany, In 1997, penstocks.de was founded by engineer and entrepreneur Karl-Otto Trawniczek. During the 20 years of its existence, penstocks.de has been carrying out several hundred projects in countries such as Germany, USA, Sweden, Russia, Turkey, China, Brasil or Chile. Sewage treatment plants, power plants, pumping stations, tunnel and civil engineering projects have been equipped with penstocks.de armatures.
In 2014, penstocks.de was converted into a limited liability company. In 2016 it became a member of the IBS corporate group. This step allowed us to enhance our sales network, to enlarge our range of products and services and to intensify our international orientation. Ever since, we have been combining our professional experience, achieving synergistic effects that allow us an even closer customer focus and assistance. Among its affiliates, penstocks.de is operating as a sales unit, executing the same construction, mounting, assistance and after sales services that have been appreciated by its customers for such a long time. Its new won partner, IBS Technics GmbH, is henceforth going to take care of the production of the penstocks.de armatures.
Our range of services includes the planning, construction and installation supervision of penstocks and other related flow control devices emerging from hydraulic steel engineering. Our manufacturer is our sister company, IBS Technics GmbH. Of course, we also supply assistance and after sales services for our customers.
Our devices have been tried and tested and have proven their reliability in the isolation and control of open channels, inlets, drains, pits, basins, reservoirs and pipelines. penstocks.de instruments are used for flow control, level regulation, flow throttling, distribution of channel flow and prevention of reflux.
