Overcome outdoor obstacles with ease
The new PYROLINE® PLMR fire protection duct not only prevents the spread of fire, but also makes it simpler than ever to overcome obstacles outdoors. It is proof that OBO provides special solutions as a standard. Every installation challenge can be managed easily.
Advantages of the PYROLINE® PLMR at a glance:
- Suitable for mounting on the FangFix concrete block, which was specially conceived for installation on flat roofs.
- Measuring 120 mm in height and 200 mm in width, the system acts as the ideal interface between neighbouring cable support systems, such as mesh cable trays.
- Can be used as a special solution in the routing of cables over firewalls.
- All products were switched over to a standardised cover screw connection, making installation even easier using standard tools.
- Fire resistance period thanks to foaming fire protection fabric inside the duct.
- Structural obstacles can be overcome easily with fittings.
Reliable and robust
If there is a fire, the intumescent fire protection mesh of the PYROLINE® PLMR foams up, thus reliably preventing the spread of fire through the electrical installation. The duct thus achieves a fire resistance period of 90 minutes. Made of stainless steel, it is particularly suitable for installations in outdoor areas. This is because the high-quality material is corrosion-resistant, rustproof and can also resist extreme temperatures or high levels of humidity.
Surveyor’s report confirms use as special solution
The PYROLINE® PLMR ducts can be used as a special solution for the routing of cables over firewalls according to the expert opinion GA-2024/070-Nau dated 15 July 2024. They correspond to the solutions according to the recommendation of the BMI+AMEV – EltAnlagen 2020 (Section 7.3.3.5 – Photovoltaic systems – fire protection): “Cables should not be run over building partitions or firewalls. If this cannot be avoided in exceptional cases, then the cables must be routed in a protected manner using cable insulation or fire protection jacketing."
