Fläkt Woods won the contract to supply the entire Turin underground system with a custom-made ventilation solution.
The metro line cut across the whole city and was ready in time for the Winter Olympic Games.
The Company has supplied a total of 44 fans, 2 fans in parallel for each of the 22 ventilation chambers. There are 11 chambers for the stations and 11 chambers for the tunnels. All fans are truly reversible long case JM Aerofoils.
Fläkt Woods supplied diffusers, silencers and dampers. The fans have 4 pole motors of 114 kW and are suitable for emergency temperature of 250°C/2h. There is a different rating for tunnel and station fans. Tunnel fans have a duty and static pressure of 210.000 m3/h @ 1000 Pa while station fans have a duty and static pressure of 80.000 m3/h @ 700 Pa.
Turin Metro has a total length of around 28 km. The metro will use the VAL (Automated Light Vehicle) system, with automated controlled trains capable of carrying up to 440 passengers. There is a train every 2 minutes in peak hours and every 4/6 minutes during the remaining operating period. This will mean 15,000 people per hour can be transported in both directions. Trains are equipped with rubber wheels, a feature contributing to higher speeds, lower braking distances and less vibration than on steel railway lines.
Trains and stations are equipped with video surveillance and smoke detection systems that, together with the absence of closed spaces and an intercom system linked to the Command and Control Point (PCC), will guarantee maximum safety for users.
