Flexible Fabric Expansion Joints

Flexible Fabric Expansion Joints – Made by MöllerWerke

To ensure that passengers reach their destination by train at a comfortable temperature, constant and reliable air supply in passenger compartments is essential.

This requires that the conditioned air must be distributed quickly and evenly throughout the passenger compartment. As the conditioned air has to be distributed over long distances, a connection solution is required that reliably and tightly compensates for tolerances and vibrations.

MöllerWerke manufactures high-quality, customised fabric expansion joints that absorb movement and compensate tolerances in air-conditioning and ventilation systems. These are one-piece solutions with customised sealing geometries that compensate dynamic and static displacements in the system. The connection at the respective interface is provided by vulcanized flanges with a sealing geometry optimized for the interface. The flanges can be manufactured in either aluminium or stainless steel.

MöllerWerke fabric expansion joints are made of silicone-laminated aramid fabric certified according to international fire protection standards, such as DIN EN 45545-2. The material is developed and manufactured at the company’s headquarters in Bielefeld. To prevent thermal bridges, MöllerWerke also offers the option of integrating additional insulating materials into the fabric expansion joints.

To find the perfect solution for customer-specific installation situations MöllerWerke offers various connection systems. These include standardized screw connections, quick-release systems and plug-in systems.

Screw connections are the most common and well-known fastening elements. It is a standardized joining element that provides a robust and durable solution. The joint can be extended using spacers for a defined tightening torque. Thus, the component is protected, and sealing is ensured.

Quick-release systems are connection systems that are used to quickly install and remove components. Assembly is considerably simplified because no additional special tools are required. Therefore, accessibility for maintenance purposes is optimised.

Plug-in systems are individually adapted mounting systems for securing mounting areas that are difficult to access or accessible from one side. The solutions are very individual and require precise interface coordination.

MöllerWerke fabric expansion joints can be purchased individually for existing systems or as a complete air duct system with MöllerWerke air ducts. Whether you choose the individual fabric expansion joints or the complete air duct system – MöllerWerke products will get you to your destination at a comfortable temperature.
