The project in brief

The Heathrow Cargo Tunnel in London was built in the late 1960s underneath Heathrow Airport to connect the cargo terminal to the central terminal area. The tunnel is crucial in facilitating various vehicle movements throughout the busy airport grounds, including transferring passengers.


After more than half a century of service, it has been decided that the cargo tunnel requires major refurbishment work to improve its condition and ensure the tunnel continues to operate effectively.  VID Fire-Kill has been appointed as provider of the fire protection in combination with the refurbishment. VID Fire-Kill’s Low Pressure Watermist TUNPROTEC® tunnel solution will be installed in the 885 m long tunnel.

Why was a VID Fire-Kill solution chosen?

The TUNPROTEC® solution offered the best technical and economical solution.

  • TUNPROTEC offered significantly less consumption of water than conventional sprinkler systems
  • TUNPROTEC allowed for a significantly smaller water reservoir and drainage system
  • TUNPROTEC offered significantly less spatial requirements for pipes and valves
