With around 41.6 million passen\u00adgers in 2024, Munich Airport is one of the busiest in Europe. High-perfor\u00admance infra\u00adstruc\u00adture is absolutely essen\u00adtial here. This incluedes the two North and South connecting tunnels: the north tunnel connects the 5-star Hilton Hotel, Hall F and the P22, P1 and P5 multi-storey parking lots with the terminal area. The south tunnel provides a direct under\u00adground connec\u00adtion between the P20, P5 and P8 parking garages and the terminal area.<\/p>\n\n\n\n

\u201cWhen one of our fans failed in the fall of 2024, we had to act quickly,\u201d recalls Thomas R\u00fchmann, Project Manager for Energy Manage\u00adment at Munich Airport. The systems in ques\u00adtion were as old as the airport itself; they worked with one large belt-driven fan for the supply and exhaust air per tunnel. This outdated tech\u00adnology had consid\u00ader\u00adable disad\u00advan\u00adtages: in addi\u00adtion to the high energy consump\u00adtion, the lack of oper\u00ada\u00adtional safety was a major issue. For this reason, simply repairing the old solu\u00adtion was not an option \u2013 only a compre\u00adhen\u00adsive retrofit. \u201cWe normally have three to four months for such projects,\u201d explains R\u00fchmann. \u201cBut here we had to find a solu\u00adtion within a month.\u201d<\/p>\n\n\n\n

Fresh air for tunnels<\/h3>\n\n

Since 1992, the north and south connecting tunnels have been venti\u00adlated by one supply and one exhaust air system each. This means a total of 4 belt-driven fans that are more than 30 years old. And also at different levels with a height differ\u00adence of 2.4 meters.<\/p>\n<\/div>\n<\/div>\n<\/div>\n\n\n

Get rid of the dirt<\/h3>\n\n

The old solu\u00adtion is also prob\u00adlem\u00adatic from a hygiene point of view due to its various wearing parts. The abra\u00adsion of the belts, for example, causes cont\u00ada\u00adm\u00adi\u00adna\u00adtion in the air ducts, or bearing grease can be distrib\u00aduted on the fan, V-belt and housing. The impu\u00adri\u00adties not only lead to cont\u00ada\u00adm\u00adi\u00adna\u00adtion of the air that the system distrib\u00adutes, but also facil\u00adi\u00adtate the spread of fire in the event of a fire.<\/p>\n<\/div>\n<\/div>\n<\/div>\n\n\n

Quite a lot to lift<\/h3>\n\n

Stephan Jendrallek and his team work with heavy tools. The old engines weigh up to 400 kilo\u00adgrams, so cranes are used. This is the only way to maneuver the aging parts through the narrow aisles of the tunnels.<\/p>\n<\/div>\n<\/div>\n<\/div>\n\n\n
