  • 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.
