Explosion Proof Enclosures

Many commercial, industrial and residential areas have an explosive environment. This kind of environment can explode if there is a static discharge spark or a switching arc or any kind of electrical discharge. Explosion proof enclosures are designed to bear up to four times the maximum pressure released by an explosion. These enclosures are therefore heavier and sturdier than ordinary flameproof enclosures. Explosion proof enclosures can also be drilled in the field.

These safety products are generally used to provide protection against lighting hazards such as fire blowups. Manufactured from different materials such as aluminum, fiber glass and heavy duty steel, explosion proof enclosures are embedded with electric current to make them more resistant. You will find these safety products being used at crucial sites such as oil refineries, gas stations and paint factories, because these sites are at greater risk of explosions.

Fire blowups are caused when internal sources of ignition accumulate. Explosion proof enclosures prevent explosions by eliminating all the forces that cause explosions. It is, however, important that you use an enclosure that has been internationally registered and certified as being completely explosion proof. You also need to install the enclosure in an area with a specific layout and pattern. This ensures that hot gases pass freely through the ventilators and allow the electric system to cool off.

The electric systems need to have a lower temperature than the point of ignition – this prevents the risk of ignition caused by a hazardous fuel. For this reason, explosion proof enclosures have a large number of flanges and are made out of tough cast steel or aluminum.

One of the signs of a good enclosure is good acceptance and a rim that sticks to the finish. It is essential to prevent scratches on the ejection surfaces of the enclosure. This is necessary to allow hot gases from passing away in case an incorrectly generated torque causes projected surfaces to break. A good quality explosion proof enclosure can be found in almost industrial area.
