Exp Purge panel
The Ex-p type of protection, referred to as pressurized enclosure, is based on the measure of purging out any explosive gases that are in a closed enclosure and then generating and maintaining a level of pressure that is higher than that of the ambient atmosphere. As the pressure inside the enclosure is higher than the atmospheric pressure, it is not possible at any time for explosive gases to penetrate inside of the enclosure. This creates an Explosion free area in which electrical devices that are not themselves explosion-proof can be mounted and operated. Purge panel
