Large Scale External Exercises and Tunnel Testing

  • Extremely persistent, meaning smoke travels 1000's of meters unlike water based systems (100's m) 
  • Experienced operators to assist in large operations
  • Thermally bouyant smoke to replicate real smoke spread
  • Adding realism to training exercises, RTC drills, testing tunnel ventilation systems / safe havens etc
  • Almost 50 years experience - unrivalled position to supply the equipment and advice best suited for you application

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. 

Testing Impulse Ventilation Systems

The smoke from the ViCount & Vulcan does not evaporate like that produced by water based smoke systems, enabling dense smoke concentrations to be achieved and maintained in exceptionally large volumes, this feature also makes the units extremely capable when demonstrating the effectiveness of impulse ventilation systems, Saccardo Nozzles and PPV systems. The smoke is capable of travelling kilometres in an enclosed tunnel environment.

Creating Thermally Bouyant Smoke

The ViCount & Vulcan also create a temperature resistant smoke, it can be added to the hot gases created by a suitable heat source to give a thermally buoyant smoke if required.

Particle Size & Safety

The class leading particle size of Concept’s smoke (0.2 micron mmd) means that minimal smoke chemical is used to produce huge volumes. This means that the ViCount & Vulcan are not only one of the world’s most efficient smoke generators but are also among the safest. 





Complete Controllability

ViCount & Vulcan smoke is controllable from a small wisp to a large plume. They are capable of producing smoke at maximum volume if required for 85 minutes. 

For external training exercises, such as public order training, where it is necessary to have a portable source of smoke, we would recommend a Concept Artem Smoke Gun. The Artem Gun is a hand-held smoke generator, capable of producing huge volumes of dense, non-toxic smoke on-demand, independent of any power supply.

Our Users Say:

"It all went very well. There was a lot of smoke and it gave a good impression of a fire around the vehicles.  Even when the ventilation came on there was still a good covering around the vehicles.

The smoke was picked up by the video incident detection system almost instantaneously.  Even short test burst were picked up straight away.

Could you pass my thanks onto your operatives, they worked very professionally."

ViCount use in Hot Fire Trainer

The machine has performed flawlessly up to this point and I purchased the machine from you at least six or seven years ago.

I have to confess I have never cleaned the orifice with the drill as you mentioned.

Actually, after the install, I have never worked on the machine again which, I am sure, is at least neglect on my part.

We originally had two smoke generators in the trainer, one fore and one aft.   The other machine (not Concepts) is quite a bit older
and it quit about two years ago but we found that the ViCount generated so much smoke we did not really need two machines.

The machine is protected from the heat of the trainer by a bulkhead with a port for the smoke to get through.

To give you an idea of the efficiency and quantity and the character of the smoke, the ceiling temperature inside the trainer as verified by two gauges reaches about 1300 degrees F. The smoke level inside the trainer is maintained quite adequately from the floor to about the
four and one half foot level but not much higher due to the temperature. We have found that it burns off at about 450 degrees F (230C).

Your smoke machine has trained hundreds of line Firefighters from all over the US including from major metropolitan Fire Departments such as Los Angeles County Fire, Pasadena Fire, San Jose Fire, Las Vegas Fire, Oakland Fire, Berkeley Fire, Sacramento Metro Fire, Cal Fire, and many federal agencies as well.

The training and experience those fire fighters receive in the intense heat and disorientingly smoky environment the ViCount helps create has without question saved lives and injuries as well as millions of dollars of property damage that may have occurred without the level of training
the ViCount helps provide.

Thank you for your help and support.
