When water-based artificial smoke is introduced into a rapidly moving air stream, the particles that make up the artificial smoke evaporate much more quickly than they do in a static environment.
So if you are looking to produce an artificial smoke that better represents the smoke created by a real fire, we would always recommend the ViCount smoke generator, the smoke from which is virtually unaffected by fast moving air streams. Used world wide PPV training centre's and to test impulse ventilation systems.
A Home Office report into PPV (Positive pressure Ventilation) by the Head of the Fire Experimental Unit, Fire Research & Development concluded that the concept behind the technique of PPV was relatively easy to understand and the equipment simple to operate, but stressed the need for extensive training.
Our Users Say:
"We use smoke generators for fire simulations and positive pressure ventilation training for approx 10 hours per week. The smoke adds realistic conditions for Fire Fighters to train in but with safety in mind.

The reaction of the tunnel environmental control system visibility sensors to the smoke was excellent, not only did the fans cut in but the volume of smoke was such that it immediately tripped a high level alarm which additionally sends a signal in the form of a general alarm to the Sussex Police Headquarters. Had the smoke been generated by a real incident the alarm would have alerted the Police to the problem in the tunnel probably before a call was made from a tunnel emergency phone."
