Reference:
In our foundry, we operate a medium-frequency furnace with a crucible capacity of 6t. In 2023, we had a complete refurbishment of the coil for this furnace performed, which we then installed in January 2024 and are currently operating. The quality of the refurbishment carried out by BV Coils is very good; the coil operates without any issues. We are very satisfied with the company's work and the price.
