Applus+ TST has a machine which can generate hot, clean smoke in order to carry out ventilation tests inside tunnels which are under construction and/or in operation.
The smoke machine, due to its design, only needs an electrical source of 230V with a consumption of 6000 W, a pressure tank of carbon dioxide (CO2) and oil in order to generate smoke.
The maximum output of smoke is between 500 m3/min and 380 m3/min.
Smoke is released at a temperature of 70o C, high enough to cause stratification and test the smoke detection systems in the tunnel.
