All our flame arrestors are to the latest ATEX requirements including a full range of end-of-line deflagration flame arrestors, in-line deflagration flame arresters and in-line detonation flame arresters are offered.
Flame arresters are fire safety devices which allow air and flammable gases to pass, but prevent propagation of flames through the device, they are passive safety devices, they have no moving parts and do not require a source of energy to function.
Flame arresters prevent the propagation of a flame front from outside of a storage tank or process vessel to the inside, or of a flame between interconnected items of equipment.
These devices employ a medium, known as the matrix, inside a casing that extinguishes the flame and, when appropriate, stops a shock wave from a detonation. Typical media are crimped-metal-ribbon, expanded metal and parallel plates.
