Explosion-proof motors from EW HOF

Full performance with uncompromising safety – this is what the explosion-proof motors of EW HOF have to offer!

We can also supply you with all of our motors as explosion-proof models. As a recognised manufacturer, we offer you our extensive know-how in constructive cooling and requisite approval. Irrespective of the motor technology, the different cooling versions can be combined to maximise explosion protection. The sub-division of explosive atmospheres into gases or dusts in the respective zones determines the areas of application of these motors. Our explosion-protected motors can frequently be found in power stations, chemical plants, mills and agitators 
as well as in material handling technology.
