Milan Genoa high-speed rail line

COGEMACOUSTIC equipments on the Milan Genoa high-speed rail line

ECE COGEMACOUSTIC concieved and manufactured the primary ventilation for the excavation of the two of Genoa bound main running tunnels (GN14N and GN15P) and the two evacuation tunnels (GN91A and GN92A) the Val Lemme project for the major actor COCIV.

For this project, the system is comprised of two primary fans installed in a bulkhead wall constructed in the ventilation chamber with their VSDs. The installed power of the two fans is 1600Kw.

Our fans supply air to a plenum which group the two fan outlets. The plenum is connected to two steel conduits of Ø2.4 m in diameter. Each conduit will supply air to two work faces plus a minimum airflow to a third gallery.

An automation system (PLC cabinets) and ATEX registration dampers allow precise regulation of the flow rate assigned to each working front.
