BURSTING PANELS - EXPLOSION VENTS
World-wide, a number of regulatory and best-practice groups have worked to improve the safety and reliability of explosion venting. These groups include NFPA, ISO and others. Elfab has adopted and
deployed their design codes and complied with all relevant legislation for over 25 years to develop our product line. As a result, Elfab can combine expert knowledge of your application and manufacturing flexibility to produce a product that meets your requirements.
Explosions in gases, vapours or dusts are not explosions in the military sense, rather they are characterised by the rapid burning of the gas or dust, which is more properly termed a deflagration. The chemical products of combustion and its physical and thermal effects cause a rapid and potentially dangerous rise in pressure in a containing vessel.
Whilst it is obvious that inflammable gases and vapours constitute an explosion hazard, it is less well appreciated that the dusts of combustible solids can also give rise to explosions; this may occur with the dusts of metal, plastics, wood, coal, sugar, starch, flour and many other commonly used products.
Elfab is unique in having panels approved as a “Protective System” II GD. (when used with an Elfab approved frame), and also a detection device II 1GD EEx ia IIC. EC-Type Examination Certificate ITS03 ATEX 11359, supplied integral to the panel, called Panel Flo-Tel™ which should be connected to an intrinsically safe circuit.
