For 25 years ASVS has supplied and certified a range of solutions to provide economical smoke control systems  in the

event of a fire.

                   

            

         

        

         

A source of inlet air must be provide to introduced cool, clear air below the buoyant smoke layer.

Where dedicated air inlets are absent, remote vents may act as inlets causing cold air to fall through the hot smoke as an inverted plume and come out of the bottom of the buoyant smoke layer as cool smoke which smoke-logs in the building. This problem is overcome by the use of low level ventilators, alternatively where high level smoke reservoirs are installed, fresh air can be supplied via ventilators in adjacent non-fire reservoirs.

 

 

 

 

 

Our solutions ensure, by calculation, that the  mass of smoke rising into the reservoir will be extracted quickly with the use of  natural or mechanical ventilators at high level to achieve the designed clear layer.

When using natural ventilators the inherent buoyancy of smoke and hot gases drives the smoke through the ventilators.

The dual role as day-to-day natural ventilators ensures that equipment is regularly tested, and the lack of any complicated fire-rated wiring and ductwork may produce a more economical fire protection system when compared to mechanical ventilators.

 

 

 

There are other considerations when designing smoke control systems, for example

ideal clear layer

the heat output of the fuel

the size of the fire

type of equipment  

type of control

interfacing with other active/passive fire protection equipment

the practicalities

safe evacuation time

All-in-all every smoke control system must provide  the solution for the specific  project and the most suitable equipment must be used. At ASVS our experience and our  unique range of exclusive products places us to the fore in every regard.
