In case of fire, fire protection curtains close wall and ceiling openings. Their construction (roll-down or folding technique) and the use of different fabrics provide for a wide range of applications as well as different protection goals, classifications and time classes. The casing and guide rails of the highly flexible systems blend almost invisibly into the building and allow plenty of scope for sophisticated architecture and open room concepts.
Various production and logistics processes call for the most diverse types of conveyor systems. If these conveyor lines pass through fire-retardant or fire-resistant walls or ceilings, the openings required for this purpose must be provided with fire protection closures to prevent the spread of fire through the conveyor system or the goods conveyed. In the event of fire, conveyor system closures (CSC for short) must close these openings immediately and automatically. Fire resistance classified according to DIN EN 13501-2 is just as important as the smooth clearance of the closing areas in the event of a fire.
A smoke apron is a part of a smoke control system which also includes other components such as natural smoke and heat exhaust ventilators (EN 12101-2) and mechanical smoke and heat exhaust ventilators (EN 12101-3). Smoke aprons restrict the movement of combustion gases within a building in case of fire.
Once closed, smoke protection curtains (SPC) restrict the passage of smoke during the phase of fire formation, so that in the event of a fire, there is enough time to rescue people and animals from the room behind the curtain and to recover material assets without the need for respiratory equipment.
The solution for issues with fire protection dampers in ventilation and air conditioning systems in conveyor processes. Stöbich offers fire protection for pneumatic conveyor lines the closing elements of which are not exposed to the flow of conveyed material. This way, the closing element cannot be damaged or contaminated by abrasive conveyed goods.
Each automatic fire protection system needs a control unit. They are critical to safety, because a failure of this function means that the entire investment into a fire protection sealing has been in vain. Control units coordinate both fire detection and interaction with other control units, such as higher-level building control systems or clearing of the closing area of conveyor system closures.
In the event of an alarm, self-closing, non-thermally insulating fire protection curtain in vertical installation position and closing direction with architectural requirements for housing and guide rails.
