Does the distribution box need air purging

Before power may be switched on, the enclosure must be purged to remove any flammable gas that might have entered the enclosure before it was pressurized. Purge and pressurization is an alternative hazardous location protection concept that allows lesser rated equipment to be used in hazardous areas by segregating the equipment from the hazardous material. What Standards Are Relevant? NFPA 496 is the standard for. e easiest to understand and use is purge and pressurization. The concept is simple, but reliable performance depends on careful sizing, monitoring, and maintenance. This continuous flow of pressurized gas prevents hazardous materials from entering the enclosure, effectively isolating sensitive electrical components from. Configuration options are available including purged pressure packing cases, short and long two compartment distance piece arrangements, flushing oil system and separate lube oil arrangements for the cylinders. These are discussed in the Ariel Sour Gas topic. When a long two compartment distance.
