Increased Safety Motors – EEx e (ATEX) – Standard Efficiency – IE1

Application

Environment where an explosive atmosphere will probably not be present under normal operating conditions and, if any, this will be for short period of time, that is, an explosive atmosphere may be present accidentally.

The environments are classified as Zone 2, groups IIA, IIB and IIC. The most common gases included in this classification are: acetone, ammonia, benzene, butane, butanol, buthylic alcohol, ethane, ethanol, acetate of ethyl, gasoline, heptanes, hexanes, natural gas, methanol, oil naphtha, propane, propanol, toluene, esthyrene, solvents in general, acetaldehyde, cyclopropane, diethylic ether, ethane, monoxide of carbon, acetylene, butadiene, oxide of ethane, hydrogen, oxide of propylene and gases containing over 30% of hydrogen.
