Steel construction work for the renovation of the pre-coolers UNESCO World Heritage Zollverein

The pre-cooler built between 1958 and 1961 in the northern area of the Zollverein coking plant

was used to purify the raw gas from tar and water by cooling.

The building consists of an approximately five-meter-high, single-storey base component in solid construction

and eight cooling towers, about 29 meters high, along with additional components such as pipelines, stairs, ladders and walkways.

On the narrow-sided outer walls in the east and west, the roof of the base building is connected via steel stairs

to reach. The cooling towers are mounted on the eight reinforced concrete bases. Center between two from

each of the groups consisting of four cooling towers, there is a stair tower made of profiled steel with steps and platforms

made of galvanized gratings, over which a walkway and suspended platforms in the upper area of the

Towers can be reached.

The industrial monument is now to be renovated.
