Tunnel Ventilation Systems

Due to the ever increasing length of tunnels, the growing number of safety requirements and increasingly stringent environmental regulations, more and more demands are being placed on tunnel ventilation systems today. Apart from meeting these demands, the design of ventilation systems must also take energy efficiency and tunnel availability into account, whether that be for road, rail or metro tunnels.

ILF has been active in the field of ventilation technology for more than five decades, focusing on the holistic and interdisciplinary design of tunnels and ventilation systems. The company has successfully designed and supported the implementation of various complex ventilation systems, and has played a leading role in more than 250 tunnel ventilation projects in over 50 countries around the globe.

ILF’s services in the field of tunnel ventilation systems include also:

  • Tunnel Lightning Systems
  • Power Supply Systems
  • Firefighting Systems
  • Doors and Airlocks
  • Fire Detection Systems
  • Radio Systems
  • Network Systems
  • Low Voltage Systems
