Stations on line 9 of Metro – Barcelona

Imtech installed electricity, air conditioning, ventilation, sanitation, plumbing and toilets in the four stations opened (Litoral, Port, Zal and new Z.F. station), a substation (traction plant) and a depot on section II of the Barcelona Viaduct. This section had a length of 4.7 km.
The electrical installation consists of two 30 kVA CTEs per station.
Ventilation was installed in the foyer storeys. The stationmaster’s room was air-conditioned using a direct expansion system with a rooftop outdoor unit. In other equipment or maintenance rooms, air extraction and ventilation were provided with specific units.
On the floors for technical facilities in the viaduct stations there are a number of premises for housing ATC and mobile operator devices, which need climate control so that the IT equipment does not operate at too high or low a temperature.
Finally account was taken of excess pressure on emergency stairs for the purpose of establishing an air flow in the station that would prevent smoke from a fire entering the evacuation routes.
