OMEX: ATEX Certified Explosion Proof Motors

OMEX is the international ATEX certified series of cast iron motors designed and built by OME Motors. These are low voltage asynchronous three-phase motors, equipped with a squirrel cage rotor with axial ventilation and a completely closed fan. These special ATEX certified explosion-proof motors are produced specifically for installation in hazardous zones and areas which are subjected to the presence of gas or combustible dusts. These motors are built to eliminate the risk of explosion and equipped with all the protections that prevent explosion: pressurized equipment; fireproof and explosion proof external structure; increased security; anti spark protection.

The ATEX Certification of the OMEX Explosion-Proof Motors.

The OMEX series includes motors built according to the ATEX directive, which classifies the equipment based on the level of protection guaranteed in dangerous areas. The term ATEX (explosive atmosphere) indicates a mixture of air and fuel that, in particular conditions of temperature and pressure and if properly triggered, can cause an explosion (deflagration or detonation). The fuel can be gas or dust. The explosion-proof electric motors of the OMEX series, also called ATEX motors, are designed to be used where maximum safety against fires and explosions must be guaranteed IEC 60079-0: 2013.
ATEX refers to two European directives that regulate explosive atmospheres:

  • ATEX Directive 2014/34 / EU concerning equipment and protection systems installed in atmospheres;
  • Directive 99/92 / EC which prescribes the minimum protection requirements for the safety and health of workers exposed to the risks of explosive atmospheres.

The explosion-proof motors of the OMEX series are ATEX certified: EEXD IIB and IIC T4.


ATEX Electric Motors For Use In Dangerous Work Areas.

Thanks to their special characteristics, the explosion-proof motors of the OMEX series are ideal for use in the chemical and petrochemical industries, in oil and gas pipelines, on offshore and coastal oil platforms, on ships, in pharmaceutical, graphic and thermal industries and manufacturing, in the mines. Furthermore, the explosion-proof motors made by OME and ATEX certified are also suitable for use in air treatment plants or in the production of systems and equipment for the collection and disposal of waste, processing of cereals, rice and sugar.
Finally, the ATEX motors of the OMEX series are effective and functional when used in combination with: pumps; compressors; industrial boiler.
