Hydrocarbon extinguishing system
Many industrial devices such as immersed power transformers contain several thousand litres of transformer oil in their internal cooling or insulation systems. These oils belong to the hydrocarbons classification and may cause severe soil or water pollution in case of leakage.
The extinguishing solutions ERT®, ERT-MODULO, EXTICOV™ and EXTICOV LHD are designed to prevent hydrocarbons pool fire risk for electrical transformers, instead of stones or pebbles in the transformer pit. Indeed the range is equipped equipped with a patented fire suppressing system of metal baffles across the top which will eliminate traditional systems such as pebble beds which become polluted and are not particularly effective and also take up part of the bund containment volume. The metal baffles are close spaced but will allow liquid through so that oil and rainwater can run into the tank, but in case of a fire the close spacing means that insufficient air penetrates and oxygen depletion occurs causing the fire to suffocate and extinguish.
Moreover this fast suffocation capacity decrease the probability of thermal runaway into the tank, which is very important in hydrocarbons fire, and make this extinguishing system so efficient, natural and simple, by acting simultaneously on 2 of the 3 component of Fire Triangle.
For safety drainage in outdoor condition, rainwater filters SPI PETRO PIPE and PETRO PIT can adapt quickly to your metallic retention tank, bund or concrete pit.
Reliable and 20 years proven models, British Standards & European approved, conformity NFC 13-200 y NFC 17-300, Patented solution and tested in European and French National Laboratory of Fire.
