any 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
