Explosion proof electric motors
Electric machines, in particular, have a variety of basic applications in various industries. Some industries such as petrochemicals, refineries, oil and gas, drilling industries and underground mines such as coal mines have explosive environments due to the temporary or permanent presence of explosive and flammable gases or dusts. The use of industrial equipment in these environments, especially electrical equipment, requires the compliance of special protection requirements and rules to make sure they will not cause any explosion or inflammation. Such equipment is called explosion-proof and should receive approval from third parties and internationally notified bodies.
Roshd Sanat Niroo Company (RSN), as a knowledge-based company registered in the comprehensive list of the Ministry of Oil and many private oil and gas industries, is a leading manufacturer of explosion-proof electric machines and has succeeded in manufacturing and testing to receive ATEX international certificate. RSN successfully delivered a wide range of explosion-proof electric motors to various industries. All explosion-proof products of Roshd Sanat Niroo (RSN) Company comply with the requirements of IEC and API standards.
