Heating Dams at the Danube

Passau - Bavaria, Germany


This project involved providing heat to six vertical lift gates with an upper and lower barrier. These gates are designed to allow the flow of water during times of high flooding. As the area experiences high freezes, the gates needed to remain frost free. Previous methods of freeze protection came with high energy consumption and were constantly failing. 


Around 1,400 meters of nVent RAYCHEM self-regulating cable was installed on the gates. These cables avoid heat build-up or burn-out, which lowers maintenance time and costs. As heat is delivered only when needed, operation and energy costs were also reduced.
