Installation of cooling towers on the 41st floor of a banking tower in Frankfurt

In August 2017, Jakob Ebling GmbH was commissioned by Apleona GVA with the replacement of cooling towers on the 41st floor of the City Haus 1 building of DZ-Bank in Frankfurt am Main.

Since the cooling towers had to be supplied in one piece and were too large for the elevators, they had to be transported via helicopter and brought into the building through an entry portal at the installation site on the 41st floor.  In order to quickly move the cooling towers to the utility room once they were in the building, Jakob Ebling built special roller conveyors which not only had the required load capacity but were also not too tall; this meant the devices could still fit through door openings.

After the scheduled helicopter transport had to be postponed multiple times because of inclement weather, the conditions were finally right on 25 February 2018. Together with Deutsche Helikopter and Heli Austria, all required official permits were secured, everything was coordinated with the police, the fire department and emergency personnel, and the special BELL 212 HP helicopter was able to successfully carry out all 12 lifts.

It is a future-oriented project because the air conditioning technology on the roofs of many high-rise buildings in major cities is ageing and must be replaced. Dense construction, underground car parks underneath open spaces and elevators that are too small for large machines often require the use of helicopters.
