Our Company
  • Our Softstarter is an all-in-one solution with the lowest possible
  • start current and without any harmonics.
  • With more than 40 years in design & manufacturing of Softstarters
  • we will guarantee the motor always starts safely.
  • We specialized in motor starting and undertake the entire
  • calculation and responsibility from design, manufacturing to test &
    commissioning of the Softstarter.
  • Regardless of industrial sector or prime mover application we will
    produce the ideal starter taking into consideration your network
    condition e.g. volt-drop, minimum start-current & time…etc.
  • To date, more than 7,500 units are installed worldwide.
  • Our close collaboration with our partner in India (ISO 9001 & ISO
    14001) enables us to deliver the most cost effective solution.

All types of squirrel cage motors
(Asynchronous and Slip-ring Motor)

What is a Harmonic Free HFDSR
Dynamic Series Reactor Softstarter?
  • Pure analogue method to control the inherent analogue process
    of motor starting.
  • Pure sinusoidal function.
  • Highly efficient air core technology for linear motor acceleration.
  • Only method to start the motor in 1.2 x FLC.
  • Build strictly as per IS 5553 part 3 / IEC 60289/076
