Fireproof door

Due to building regulations, walls or ceilings that serve as fire protection partitions in buildings may not be provided with openings. Exceptions are permitted if the use of the building requires this. If conveyor systems penetrate building closures that consist of fire-resistant and smoke-proof walls and ceilings due to the fire protection concept, the resulting openings must be closed by conveyor system closures (FAA) in case of fire or malfunction. For this purpose, we offer you solutions specially tailored to the respective application. The different types of conveyor systems (e.g. roller, belt, chain, etc.) and whether the conveyor system is unseparated or separated with a gap in the closing area of the fire protection door must be taken into account. In addition to an approved hold-open system (door control), control systems are also used to ensure that the closing area is released in the event of a malfunction or fire. Due to the high requirements, a conveyor system closure differs significantly from a fire protection door and is therefore also tested according to its own guideline. Among other things, these also stipulate a minimum fire resistance duration of 90 minutes (EI 90). Our conveyor system closures are based on proven design principles. This results in the following advantages for the operator: inherently stable steel construction, designed for a long service life permanent function control of the components quick and inexpensive replacement of wearing parts low maintenance costs
