Electrical explosion protection equipment


Control and automation components which are not available in explosion protected versions can be used in hazardous areas by applying the types of explosion protection “flameproof” Ex d and “purge and pressurisation” Ex p. Both technologies allow the integration of standard industry components in accordingly certified enclosures; the explosion protection method is different, though. Ex p prevents the ignitable gas from entering the enclosure while Ex d contains a possible explosion inside the sturdy enclosure. Both types of explosion protection can be combined and allow, by addition of Ex e control elements, a tailor-made design of the solution for the specific application, be it chemical and pharmaceutical production plants or oil and gas processing.
