Modular Compensation
Built for Zero Downtime

The GRIDFIX Series, developed by Forte Energy, consists of reactor-based, thyristor-switched modular compensation drawers designed for the high-speed, reliable and scalable compensation needs of modern industrial facilities.

These systems maintain a stable power factor even during sudden load changes, increasing energy efficiency and extending system life. Its drawer-type design turns each stage of the system into an independent module, enabling fast maintenance and easy expansion — allowing the faulty module to be replaced without shutting down the entire system.

  • Ultra-fast thyristor switching with a ≤10 ms response time
  • Harmonic filtering with detuned reactors (%7 or %14)
  • Easy maintenance and expansion thanks to modular drawer design
  • Plug & Play modules — replacement without production downtime
  • Long-life capacitors (>250,000 hours)
  • DSP-based intelligent control ensuring continuous cosφ ≥ 0.99
  • GRIDFIX drawer panels comply with IEC 61439-2 Form 4B standard
