A historic cooling tower remodeled with an internal steel frame as well as 2 intermediate levels for the State Garden Show of 1997 in Gelsenkirchen. Aside from these additions, the cultural architecture was left undisturbed. The forever changing appearance of water in nature and its role in the tower‘s cooling function were the main themes for the exhibition „Cooling Tower Water Phenomenon“. From an elevated platform, directly over an intricate structure of pipes, channels, and braces, the visitor is in a perfect position to witness the turbulent flow of air and water. A system of accent lights illuminate the inside of the tower and produce rainbows as they interact with the rising condensation clouds. Projected images and sound patterns blend between nature and technic. The previous function of the cooling tower is also displayed. One section of the water channel system located under the see-through platform occasionally overflows. Through several round openings cold water exits through the grated surface underneath. A stairway takes the visitor underneath the tower framework. Here it‘s possible through a „water window“ to see how water mist disappears through the framework into the pump room below. Unfortunately, in 2000, the cooling tower was destroyed by arsonists.
