KONČAR-MES IN STEP WITH LEADING MANUFACTURERS OFFERS IE4 AND IE5 MOTORS IN EXPLOSION PROTECTION

PERFECT MATCH with reduction of energy losses compared to conventional solutions with return of investment in less than two years. Končar-MES was among the first and alongside leading manufacturers to certify high-efficiency motors in flameproof protection.

Ex protection marking and usage:

II 2G Ex db IIC T3, T4, T5, T6 Gb
II 2G Ex db eb IIC T3, T4, T5, T6 Gb
II 2D Ex tb IIIC, T160°C, T130°C, T100°C Db

  • High efficiency IE4 and IE5
  • Reduces energy losses by ut to 40% compared to conventional solutions
  • Return on investment – less than two years
  • Guaranteed total system efficiency and optimized process control
  • Fully interchangeable due to IEC/Cenelec compliance
  • Lower bearing and winding temperatures (longer bearing lifetime)
  • Reduce CO2 emission

Main applications
