The DUAP Group currently consists of DUAP Switzerland in Herzogenbuchsee, DUAP USA in Miami, and Alliance Diesel Refit in France (ALLIANCE). While DUAP Switzerland and USA are primarily responsible for the production, reconditioning and distribution of our fuel injection systems, ALLIANCE in France is primarly focussing in engine service on ships and on power plants. In this constellation, DUAP Group, with its over 150 employees, has been an important, independent solution provider and development partner for fuel injection systems since many years.
