CELES IS generators are static frequency converters. Their power range is 50 kW to 4 MW for applications that require operating frequencies between 500 Hz and 50 kHz.

The CELES IS is recommended for induction heating applications in a variety of industries:

  • Heating for steel workpieces (strips, rails, tubes, rods, etc.)
  • Brazing for electric motors
  • Metal and glass oxide melting
  • Quenching
  • Pre-forming heating
  • Graphitization furnace
  • Ozone generator
  • Drying for line workpieces, paints, etc.

Fives tests its generators and their applications on a testing platform at full power and full current, so its customers know we can stand behind the performance of our equipment.

The Celes IS equipment range guarantees:

  • Low operating costs
