  • I would accentuate Duplico as a very positive example of innovation and the application of the latest technologies and trends, such as "state-of-the-art" remote control systems. We are proud of the numerous applications of Siemens systems and solutions in water management, industry, and energy projects. In current Croatian surroundings, I also perceive Duplico to be an inspiring "role model" of successful digital transformation of its own business processes.

  • The peculiarity and the key to the long-term success of the Duplico company lies in the exceptional agility and commitment of the Duplico team in providing the best service to clients, openness to adopting new knowledge and innovative technologies, and a high level of expertise and cooperation.
