Advanced Digital Inverter

  • Microprocessor controlled IGBT invertors, provide precision PWM output power.
  • Constant input power factor across all loading conditions resulting in cos phi >0.95.
  • Monitor and diagnose data anywhere in the world with digital remote access.

Selectable Frequency Control

  • Low frequency induction gives deep heat generation and rapid heat soak times, LFi provides a selectable frequency output capability of 20-200 Hz to allow for heating process optimisation.

Zone Synchronisation

  • LFi coil zones have phase synchronisation to eliminate magnetic field cancellation between zones resulting in improved temperature uniformity and coil efficiency.

Compact Footprint

  • 800kW across up to 5 independently controlled zones in a single compact 2.0m x 2.4m cabinet.
