Estel - Model 22 kHz / 50-500 kW -FCI Generators for Induction Furnaces
Principal difference from TFC is in wider range of adjustment (with less influence to grid), more compact dimensions and higher frequencies working ability. Manufacturing of converters with power, voltage and frequency characteristics different from standard ones are available on Customer’s demand. All generators have IGBT-modules from world leading manufacturers.

- Power: 50 – 500 kW
- Frequency: 0,1 – 22 kHz
- Microprocessor control system
- IGBT-modules from world leading manufacturers
- Designed to comply with RoHS and REACH requirements
IGBT modules as power inverter elements seriously simplified generator’s power scheme:
- leveling reactor critically decreased in gabarites
- start block excluded
Thus overall gabarites and weight were decreased accordingly.
Microprocessors system principally widened custom characteristics.
On a contrary to TFC, FCI generator can work under 
that increases efficiency.
Generators may be delivered in the following set:
- generaator
- generator with integrated cooling system
- monoblock power supply unit (generator, capacitor bank and cooling system)
- generator with separate interface cabinet
- generator with separate cooling system cabinet
