Design
Our highly skilled engineering teams focus on optimization and continuous improvement resulting in the highest performance available on the market (efficiencies, life span and mechanical behavior).

For this purpose, we use the best computation tools relying on Finite element analysis (FEA) and 3D CAD design.

We work closely with turbine manufacturers to refine system designs and ensure flawless performance of the turbine-generator system on site.

Production
Our production site is equipped with state-of- the-art machinery, and we achieve unbeatable product performance through controlled high-quality components and processes at every step.

CNC plasma and laser cutting tools, precision form-wound winding, and vacuum-pressure impregnation are some of the equipment and processes used by qualified and dedicated workers.
