Dowaldwerke Dippoldiswalde and Dowaldwerke Bremen are companies of Richard Grießbach Holding, an owner-managed, medium-sized group of companies with approximately 300 employees. We develop and produce vacuum toilets, gangway doors, interior doors, partition walls and entrance systems for the largest railway vehicle manufacturers in Europe.
At the beginning of 2016 we took over the business of our sister company Pneumatik/Hydraulik GmbH, thereby expanding our product range to include pneumatic and hydraulic components. With these product groups we supply items such as coupling components for high-speed trains and level control systems.
We employ a large part of our resources in the field of development and design. This enables us to react promptly to developments on the market as well as to new customer requirements.
