In hazardous duty applications, such as chemical processing, mining, foundry, pulp and paper, water management or petrochemical, motors have to comply with the strictest safety standards for the protection of life, machines and the environment. With the explosion-proof motors from Siemens you are getting more than the basic safety requirements. These high efficient motors exceed EPAct efficiency standards and are UL® listed for hazardous gas environments (Class I, Group D, Class II, Groups F & G, Division 1 or Class I, Groups C & D, Division 1). Upgrading to Class II, Group E in a Division 1 area is also available. Designed and manufactured for rugged operation, these NEMA motors can withstand the harshest industrial conditions with maximum performance for reliability and efficiency.
