Explosion-Proof Motors – ATEX
Siemens explosion-protected motors exceed basic safety requirements, operating reliably even under the most extreme conditions. In hazardous environments such as chemical plants, the oil industry or gas works, our rugged EEx motors comply with the strictest safety standards for the protection of life, machines and the environment. All explosion-protected motors from Siemens are tested by the German Federal Institute of Science and Technology (PTB) or German Coal and Still Technology Company (DMT).
