Floating roof storage tanks often contain highly flammable products, posing a risk of catastrophic fires. If the fire is not detected early, it can cause significant loss of plant, downtime of production and in severe situations, even risk to life. These can have a considerable financial or environmental impact.
The leading cause of fires is the ignition of flammable vapours leaking from a worn or damaged rim seal. Early detection of incipient fire is crucial for effective fire suppression measures, as it prevents the fire from growing and spreading.
The design and size of storage tanks can vary significantly between operators and sites, necessitating a flexible solution to meet individual needs. With its ease of installation and low maintenance, Linesense digital Linear Heat Detection (LHD) cable provides a cost-effective answer. The LHD cable can be cut to length as required, and a single cable can protect the largest of storage tanks.
Linesense Linear Heat Detection cable is a reliable and straightforward product that provides uninterrupted detection along its length, ensuring the complete circumference of the rim seal is protected.
The LHD cable installed around the rim seal of a floating roof tank requires an electrical connection between the roof level and a junction box at the top of the tank wall. The connecting cable needs to allow for the rise and fall of the floating roof as the tank fills and empties. The cable reeler automatically adjusts for the movements of the roof, dispensing cable out as the level falls and reeling cable back in when the level rises. The Automatic Cable Reeler is installed at the top of the tank wall and provides a four-core cable to connect to a junction box located on the tank roof.
