IE3 High Efficency Ex d Explosion Proof Motor
Industry type:Productivity and energy
Product model number:AEHFXZ 4P-20HP
award 3

a.Product design:

In the world, the three phase induction motor energy efficiency standards have increased year by year, the North American NEMA Premium efficiency standard 2010.12/E ~ has entered into force, the EU standard IEC60034-30 efficiency (IE2) 2011.06/16 ~ has come into effect, TECO Release IE3 high efficiency flameproof motor, snatch the strong demand for high-efficiency motors of explosion-proof market.


the product has a non-conductive explosion fan, and it does not produce sparks, arcs and overheating when the motor is in start-up and operation status. Flameproof designs comply with IEC 60079-0, IEC 60079-1 regulations IEC, and CNS 3376-0, CNS 3376-1, and they are also applied to the dangerous places in Zone 1 & 2.

c.carbon reduction:

TECO high efficiency flameproof motor, compared with existing CNS high efficiency motor, it can reduce 15% motor losses, for example, the 4P-2HP motor operated 8760 hours per year, it can be reduced about 770 Kg CO2 per year.
