Topwind. Since 2008.

Johan Top and Ruud Kerkhof established Topwind in 2008. They met each other in 1993 when being colleagues at local turbine supplier Lagerwey, and from that period onwards served the wind industry in various capacities and multiple businesses.

Our mission.

We know for certain how technology can positively contribute to your business case, and as such assist you in achieving the best performance and highest efficiency. This is our mission and what drives us every day again. We will support you with dedicated know-how, fresh ideas and our comprehensive in-house implementing capabilities.
