Explosion-Proof NEMA Motors

ATEX NEMA Ome Motors are explosion proof motors designed and approved for application in hazardous environments where certain gases or other explosive materials are present. NEMA explosion-proof motors are built to withstand an internal explosion of gases or vapours and to prevent ignition of the gases and vapours surrounding them from any internal explosion. NEMA explosion protection motors are low-voltage three-phase electric motors that comply with all national and international standards and requirements and are suitable for particularly demanding process applications, on land or at sea, in oil and gas pipelines, in refineries and petrochemical plants, in floating platforms for oil storage, production and unloading, in liquefied natural gas (LPG) plants. NEMA Atex motors are perfectly capable of operating in adverse environments, such as explosive atmospheres, extreme temperatures, corrosive dust or humidity.
