The installation of electrical equipment in heavy processing facilities, such as oil refineries and chemical plants, can be very hazardous. In such demanding settings, flammable gases are likely to be present, so it is vital that every possible precaution is taken to ensure any sparks caused by electrical switching activity or fault conditions do not ignite these gases. To address this problem, Gonsion Technology has developed an industrial PC with an enclosure which ensures that there is no possibility of an internal spark triggering an external explosion. (flameproof/explosion proof) standard.
