    Tunnel solutions for the tunnel air flow

    Tunnel ventilation systems are designed to enable a sufficient throughput of air to be maintained to ensure a safe operating environment for users. These systems consume large amounts of power and need to be operated as efficiently as possible. To do this it is necessary to know the effectiveness of the system in terms of air flow and direction developed within the tunnel. The TunnelTech 301 is a single point ultrasonic flow monitor that is unaffected by traffic flow and sound reflections. It is designed to...

  • Smoke generator device for wind tunnel studies

    For producing a point source of smoke in a wind tunnel environment, Concept have the Aerotech smoke system, with a heated tip on the end of a thin wand. For seeding a wind tunnel for LDA/PVA type work the ViCount 1300 system is normally supplied. This can produce either water or oil based smoke with minor re-programming, so it is a very adaptable solution. The ViCount is such a versatile machine, that its capable of everything from seeding the world’s largest wind tunnel (NASA AMES) through to producing fine...

  • 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...

    Tunnel solutions for the visibility monitor

    The TunnelTech 101 Visibility Monitor (VIS), is an essential part of any road or rail tunnel safety system. It monitors the Visibility within the tunnel and ensures that the tunnel ventilation system provides sufficient clean air for drivers to clearly see the road ahead. The TunnelTech 102 Cold smoke monitor (CSM detects smoke from a fire to rapidly warn the operator of the hazard. Secondly, used in combination with other TunnelTech 101 VIS monitors, the operator can quickly detect the locus of the fire if it...
