Benefits

Purge and pressurization make it possible to use standard general-purpose enclosures in hazardous areas.
Purge and pressurization components are easy to use and implement—they can be assembled onto the enclosure, then certified for hazardous-area operation. 
Purge and pressurization is a globally recognized hazardous area protection method.
Equipment within the pressurized enclosure stays clean and isolated from the outside atmosphere because of the positive pressure within the enclosure.
Purge and pressurization systems can be configured so that a protective gas constantly flows through the enclosure to keep the equipment cool. If the temperature begins to elevate, the protective gas supply increases. It decreases once the equipment temperature returns to normal. The system can alarm and/or shut down the equipment if the temperature is too high. Equipment will last longer if the inside of the protective enclosure is kept clean and cool.
Unlike explosion-proof or flameproof enclosures, the atmosphere within the protective enclosure cannot ignite and damage the enclosure equipment. Explosion-proof enclosures can be costly and heavy, with long lead times. Purging a standard enclosure reduces cost, weight, and lead times.
Inert gas, like nitrogen, allows equipment to operate within a gas analyzer housing without risk of a fire.  
It is easier to get global certification on a protective enclosure, because purge and pressurization components can be universally certified.
