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 according to DIN EN 13501-2 as well as the smoothly clearing of the closing area must be respected in case of release.

Fire protection curtains are sealing 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 invisible in the building and provide much scope for design of sophisticated architecture for opened designs.

A smoke curtain is a part of an unit keeping areas free from smoke and may include building parts like natural smoke and heat venting systems (EN 12101-2) and automatic smoke and heat venting systems (EN 12101-3). Smoke curtains restrict thereby the movement of fire gases inside a building in case of fire.

Smoke protection closures obstruct in closed condition 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.
