    Tunnel monitoring

    Car tunnels need ventilation in order to keep air pollution below the limits. When the pollution levels reaches a setpoint, the fans must be started and kept running until the pollution levels decreases.

  • Smoke generator device for large scale external exercises and tunnel testing

    Making smoke in a very open environment or external environment can be a challenging! An oil-based smoke generator, such as a ViCount system, can produce dramatically more artificial smoke than multiple water based systems. This is due to the fact that the smoke ViCounts produce, being oil-based, does not evaporate in the same way and speed that water-based smoke does. The smoke from a ViCount smoke generator will travel for 1000`s of meters, compared to a typical water based smoke machine that may produce a smoke visible for 100 meters. Just one ViCount or Vulcan can replace 10 or more conventional water based smoke systems. ViCount`s have been used world wide for many tunnel smoke simulations, be it for RTA training / evacuation exercises or tunnel ventilation testing.
