Mechanical, Electrical & Hydromechanical Equipment

Electromechanical

Our teams in the field of electromechanical engineering provide both the complete design work and technical specifications for new build schemes, and for the rehabilitation and upgrading of existing plants. Our experts develop exacting solutions for turbine and pump concepts, generators, excitation and protections systems, emergency and cooling systems, fire protection and HVAC systems, switchyards and substations, instrumentation and control systems, and transmission & distribution.

Hydromechanical

We provide expertise in mechanical engineering and hydro mechanical engineering in hydroelectric power plants starting from feasibility studies to commissioning. We have extensive experience in the design of gates, valves, penstocks, steel liners and related equipment, as well as expertise in metallurgy and dynamic processes. We are equipped with the full spectrum of measurement devices for measuring thermo dynamical efficiency of Francis and Pelton turbines as well as pumps and pump turbines.
