Flameproof Totally Enclosed Fan Cooled Motors are explosion–proof electric motors in a fully enclosed air-cooled enclosure.
Explosion-proof electric motors Marelli Motori cover a power range up to 1600 kW and have an operating voltage of 400V, 690V, 3000V, 6000V (individual adjustment of the operating voltage is possible). The design of the electric motor provides protection of the system not lower than IP55, IP56, IP65.
Explosion-proof electric motors 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 operation in explosive atmospheres".
Areas of application: centrifugal, reciprocating compressors, heat exchangers, superchargers, pumps, extruders, expanders, conveyors, mixers, mills, cranes.Explosion-proof electric motors depending on the field of application and the category of the room Marelli Motori they are classified by series:
D5H – asynchronous electric motors in an explosion-proof shell version Ex d II B T4 Gb;
D5L – explosion-proof electric motors version Ex de II B T4 Gb
B5L – electric motors with a high degree of protection version Ex nA II C T3 Gc.
Detailed information about all explosion-proof Marelli Motori electric motors can be found in the explosion-proof motors section.
