Flameproof Totally Enclosed Fan Cooled Motors are explosion–proof electric motors in a fully enclosed air-cooled enclosure.
High-voltage electric motors Marelli Motori D5H series in an explosion-proof shell (degree of protection ATEX II 2G Ex d IIB T4 Gb) are designed for use in places where an explosive environment is likely to occur created by mixtures of air and gases, vapors, mists (media saturated with propane, industrial methane, ammonia, gasoline, ligroin, petroleum, acetone, alcohol, by diethyl ether pairs). Electric motors for use in explosive areas of premises and outdoor installations (gas mixture category II).
Areas of application: centrifugal, reciprocating compressors, heat exchangers, superchargers, pumps, extruders, expanders, conveyors, mixers, mills, cranes.
Explosion-proof Marelli Motori electric motors They are certified and comply with the requirements of the Technical Regulations of the Customs Union TR CU 012/2011 "On the safety of equipment for work in explosive atmospheres".
