Fire protection curtains are seal openings in walls and ceilings in case of fire. The constructional set-up (rolling- or folding technology) and the use of different fabrics offer a wide application spectrum as well as different protection targets or classifications and time classes. Casings and side guides of those flexible applicable systems are integrated almost invisibly in the building and provide much scope for design of sophisticated architecture for opened designs.
Manifold production - and logisitc processes require different construction types of conveying systems. If the haulage drifts are passing through fire-retarding resp. fire-resisting walls or ceilings, the necessary openings must be provided with fire protection closures to avoid the expansion of the fire by conveyor technique or by conveyed material. In case of fire the conveyor system closures have to seal those openings immediately and automatically. Thereby a classified fire resistance as well as the smoothly clearing of the closing area must be respected in case of release.
A smoke curtain is part of unit keeping areas free from smoke and may include building parts like natural smoke and heat venting systems and automatic smoke and heat venting systems. Smoke curtains restrict the movement of fire gases inside a building in case of fire.
In closed condition smoke protection closures restrict the passage of smoke in the phase of fire formation so as to enable the rescue of people, animals or materials assets in case of a fire in the room positioned behind it without the need of breathing protection.
The solution to problems with fire protection dampers for ventilation and air conditioning systems in conveying processes. Stöbich offers fire protection for pneumatic conveying lines where the closing elements are not exposed to the flow. Thus, damage or contamination of the closure element is avoided by abrasive conveyed goods.
Control systems are necessary for all automatic fire protection systems! They are safety-relevant, because without their function or in the event of a malfunction, the entire investment of a fire protection partition would be useless. Controllers coordinate both fire detection and the interaction with other controls, like superordinate building control or the retraction of the closing area at conveyor closing area.
Efficient smoke protection curtain at high pressure levels and smoke temperatures up to 392 °F: The Stoebich Smoke Curtain T smoke protection curtain offers reliable protection against smoke penetration and satisfies the requirements defined for smoke protection closures acc. to DIN 18095-1. The system is approved up to a size of 23' x 14.8' – larger dimensions are technical feasible and can be realised on request. The Stoebich Smoke Curtain T can securely seal uneven floors by means of its elastic closure strip. In combination with other compensation measures and the use of fire protection fabric, additional protection goals can be realised. The curtain is closed without power using the force of gravity. In accordance with fire tests the Stoebich Smoke Curtain T smoke protection curtain (if the correct fabric is used) can withstand the effects of the fire for more than 90 minutes and also reduces the radiation heat.
