Cantene developed with Essecì Impianti a system able to disconnect fluid dynamically floors from the stairs. The system QSLAVE® SM / SV produced by Essecì Impianti is able to keep the pressure level inside the filter avoiding the door remain open.
The effectiveness of the system was evaluated passing through CFD analyses. The following parameters were taken into account:
• the room in which the fire occurs;
• the corridor that connects the room to the exit at the floor;
• the filter;
• the stairs;
By the CFD model alternative design solutions to keep free of smoke the filter have been compared.
