The Fränkische Rohrwerke FPKu-EM-F-H0 25 is a medium-sized plastic conduit made of polyphenylene ether (PPE), finished in grey (RAL 7035). It is specifically designed for surface mounting installations in industrial and plant engineering, as well as for standard applications in electrical and building technology. The conduit is supplied in straight lengths of 3 metres and features a one-sided formed socket, enabling simple and secure connection to additional conduit sections. The use of PPE as the material ensures high mechanical strength and thermal resistance, supporting its suitability for demanding operating conditions in industrial environments.

Plastic conduit made of PPE offers excellent resistance to mechanical stress and chemical influences. The halogen-free characteristic is a key feature, as it ensures that no toxic or corrosive gases are released in the event of fire. This enhances safety in use, particularly in areas with high visitor traffic or in technical installations where fire development and smoke emission are critically assessed. The non-flame-propagating property further contributes to fire retardancy and supports compliance with fire protection regulations.

The product is suitable for the installation of circuits with function retention (E30, E60, E90), meaning that electrical circuits remain functional for a defined period even during a fire. This property is particularly important in emergency power supplies, alarm systems, or fire protection installations. System testing in accordance with VDE 0605 and DIN EN 61386-22 confirms compliance with relevant standards for electrical installations. The minimum crush strength is 750 Newton per 5 cm, ensuring the mechanical robustness of the conduit under load.

Applications include primarily surface mounting in production halls, factories, warehouses, and other industrial facilities where open cable routing is required. It is also suitable for use in buildings with high fire protection requirements, such as hospitals, administrative buildings, or public institutions. The grey colour (RAL 7035) blends well into industrial environments and is visually neutral, so the conduit does not stand out prominently.

Technology explained simply: The conduit is made of PPE, a thermoplastic material with high heat resistance and good mechanical strength. The one-sided formed socket allows for quick and tool-free connection between conduit sections. The halogen-free property means the material contains no halogens (such as chlorine or bromine) that could release toxic gases when heated or burned. Standards VDE 0605 and DIN EN 61386-22 define requirements for electrical installation and mechanical properties. The minimum crush strength of 750 N/5 cm guarantees that the conduit will not deform or be damaged under static load.

Compatibility and accessories: The FPKu-EM-F-H0 25 is part of a comprehensive system of installation systems from Fränkische Rohrwerke. It can be combined with other components such as elbows, T-pieces, junction boxes, or couplings, all of which are system-tested. Using system components ensures uniform quality and secure connection technology. Installation is carried out in open surface mounting, where the conduits are directly fixed to walls, ceilings, or scaffolding.

Installation and mounting: Mounting is performed by attaching the conduits to the desired location, using the one-sided formed socket to connect to additional conduit sections. Installation is done in open surface mounting, with the conduits visibly routed. The straight length of 3 metres enables efficient installation with a minimal number of connections.

Operational advantages: The halogen-free and non-flame-propagating properties increase safety in the event of fire. The high mechanical strength and thermal resistance of the PPE material ensure long service life and low maintenance requirements. System testing and suitability for function retention (E30/E60/E90) make this conduit a reliable choice for critical applications in electrical installation.
