Purged And Pressurized Motors For Zones And Divisions

Electric motors have been used and pressurized technique or the explosion-proof enclosure in zone 1 and division 1 hazardous areas for many years. These motors operate in hazardous (classified) locations where an explosive gas or vapor atmosphere is likely to be present in a normal operation. Motors operating in this area require special protection against igniting the explosive gas or vapor. To operate these motors safely, special protections such as the purged and pressurised technique or the explosion-proof enclosure are required the large fabrication frame motors are typically protected by the purged and pressurized technique.
