Fire protection ducts – reliable protection for escape and rescue routes
The unique, wide product range in the field of fire protection makes OBO one of the few providers offering solutions for all three protection aims in the event of fire: limiting the spread of fire, protecting escape and rescue routes, and maintaining the function of important electrical systems. With our solutions, we help protect people and property as effectively as possible in the event of fire.

Installations must not pose additional fire loads
In the area of emergency and escape routes, an installation must not pose an additional fire load. This requirement must be complied with through the appropriate installation types. One of these is installation in fire protection ducts. The ducts provide protection against the effects of a cable fire. To ensure their reliability, the ducts are tested at independent testing institutes. The electrical cables are burned within the duct. During the entire classified time specified by the testing standard, neither fire nor smoke may escape from the duct system. In this manner, it is possible to prove that the fire load is effectively encapsulated in the duct and that the fire protection duct offers secure protection of escape and rescue routes.
The OBO range of fire protection ducts
OBO offers an extensive portfolio of safe and tested fire protection ducts, including the PYROLINE® Rapid duct system, which is made from sheet steel and features a profiled cover-locking contour and an intumescent internal coating.

Designed specifically for PV systems, we offer the PYROLINE® Sun PV for routing photovoltaics systems inside and outside of buildings, as well as the PYROLINE® PLMR stainless steel ducts.
