Explosion-proof motors from EW HOF

Full power with reliable safety – explosion-proof motors from EW HOF!

All our motors are also available in an explosion-proof version. As an accredited manufacturer, we provide you with our comprehensive know-how in design and certification requirements. The different explosion-proof designs can be combined regardless of the motor technology. The subdivision of explosive atmospheres into gases or dusts in the respective zones determines the areas in which these motors are used. Our explosion-proof motors are frequently used in power plants, chemical plants as well as mills, agitators and industrial trucks.
