SER Drives and RCD Upgrade:

  • Extend the operating speed range of the mill, allowing the plant to adapt their processes to the new requirements as the production develops
  • Increase the load capacity of the SER drive or RCD allowing processing more material in the plant.
  • Provide reactive power compensation with the SER drive for unity power factor.
  • Drastically reduction of harmonics content generated by the SER drive.
  • Upgrade discontinued parts with new ones with fully functionality and continuity (PLC, HMI, power semiconductors, etc)
  • Protection against grid faults and/or asymmetric voltage drops.
  • Cooling improvement for extreme hot environments.

LRS Upgrade:

  • Starting torque and speed monitoring and control.
  • Frozen charge protection relay.
  • Upgrade from AK-EP to MAK300 type.
  • Starting monitoring, conductivity monitoring…
  • Increase of power/torque to allow more load in the mill.
  • Modification for operation with SER Drive.
  • Improve resistance ratio to reduce the torque pulsation at the beginning and end of starting.
  • Protection against grid faults and/or asymmetric voltage drops.
  • Cooling improvement for extreme hot environments.
