Many of the 4,800 oil terminals around the world use floating roof tanks (FRTs) for the storage of combustible or flammable petroleum products. Most codes and regulations require fire detection at the floating roof seal, where the risk of fire is the greatest. While linear heat cables are a traditional detection choice, there is now an alternative technology that offers greater detection speed plus easier installation and less maintenance for Zone 1 and 2 applications.
Optical flame detectors offer very fast response speed (typically 3 to 8 seconds), minimizing the chances that a fire will become a catastrophic event before an alarm reaches the fire control system. Unlike linear heat detectors, optical flame detectors can also provide detection coverage for the entire space above a floating roof.
Optical flame detectors can be flange mounted (as shown) for internal floating tank applications or pole mounted for open-roof FRTs. Optical flame detectors provide a wide range of coverage along the perimeter of floating roof seals.
