Important of smoke and heat vent systems
Most of the people exposed to fire die due to smoke inhalation, not burning. Smoke from fire covers all rooms and spaces within minutes, creating a life-threatening situation. Toxic poisoning by inhaled smoke causes loss of vision, concentration difficulties, and loss of sense. Therefore, smoke prevents escape in time.
To prevent this, evacuation systems prevent the smoke from accumulating in the room by evacuating it before cooling the fire. In this way, the fresh air necessary for survival is provided, as well as the panic and anxiety caused by smoke is prevented. In the areas where the smoke is evacuated, it becomes easier for the fire brigade to intervene the interior and to control and extinguish the fire. Natural smoke evacuation is provided by the aerodynamic roof vents. Smoke evacuation flaps are used for these aerodynamic vents.
Smoke Evacuation Flap Models
Single-Flap Systems
It opens at an angle of 140 - 165° in case of fire, providing an effective smoke evacuation. It provides daily comfort ventilation thanks to its 30cm or 50cm ventilation motor on it. They can be used for daily natural ventilation of industrial facilities in good weather conditions. The systems run with pneumatic or 24V pistons. Any number of flaps as determined based on smoke zoning can be controlled from the control panels or fire warning system as well as manually. The flaps can be also opened automatically by the thermal trigger (glass bulb) on it if a certain temperature is reached. They are closed manually after the fire is extinguished.
The system should be inspected at least once a year. The trigger CO2 tubes on the flaps and the CO2 tubes on the main panels are checked. The empty ones are replaced with new ones. In 24V electrical systems, it is sufficient to check the batteries in the main panel These flaps used in natural smoke evacuation systems must be tested and certified according to the EN 12101-2 standards.
Double-Flap Systems
It opens at an angle of 90° in case of fire, providing an effective smoke evacuation. It opens at an angle of 90° for daily natural ventilation, providing an aerodynamic ventilation. They are ideal for industrial facilities with hot processes. The systems run with pneumatic or 24V pistons. Any number of flaps as determined based on smoke zoning can be controlled from the control panels or fire warning system as well as manually. The flaps can be also opened automatically by the thermal trigger (glass bulb) on it if a certain temperature is reached. They can be closed from the panel without climbing up the roof.
The system should be inspected at least once a year. The trigger CO2 tubes on the flaps and the CO2 tubes on the main panels are checked. The empty ones are replaced with new ones. In 24V electrical systems, it is sufficient to check the batteries in the main panel These flaps used in natural smoke evacuation systems must be tested and certified according to the EN 12101-2 standards.
Louver Type Systems
It opens at an angle of 90° in case of fire, providing an effective smoke evacuation. It opens at an angle of 90° for daily natural ventilation and an ideal system for industrial facilities where intense smoke is generated. It is preferred especially for very windy regions with a high snow load. The systems run with pneumatic or 24V pistons. Any number of flaps as determined based on smoke zoning can be controlled from the control panels or fire warning system as well as manually. The flaps can be also opened automatically by the thermal trigger (glass bulb) on it if a certain temperature is reached. They can be closed from the panel without climbing up the roof.
The system should be inspected at least once a year. The trigger CO2 tubes on the flaps and the CO2 tubes on the main panels are checked. The empty ones are replaced with new ones. In 24V electrical systems, it is sufficient to check the batteries in the main panel These flaps used in natural smoke evacuation systems must be tested and certified according to the EN 12101-2 standards.
These systems can be also easily adapted to facades, sawtooth roofs, glass or polycarbonate skylight systems.
