Description
UL Listed emergency vent (pressure relief only) used on aboveground storage tanks, as a code requirement that helps prevent the tanks from becoming over-pressurized and rupturing if exposed to fire. The vent must be used in conjunction with a “normal vent”. Correct application of this vent requires proper vent size and selection for the tank system in order to meet the specific venting capacity requirements. The new design increases protection against weather, improves manufacturability and helps limit and control dust accumulation.
