In its production programme FEMOD includes a wide assortment of inductors for all metalurgical applications. They feature various windings for quenching, induction heating, high-frequency welding, melting, local preheating, thermal treatment, etc., with power ranging from several tens of watts up to over 2 MW, operating frequences of 50 Hz up to 450 kHz, and all voltage levels used for this application.
Most commonly used material for inductors is pure electrolytic copper, or any other alloy or metal for special application required by customers.
Cooling fluids for inductors are water, air, various emulsions and cooling oils or gaseous or liquid mixtures adapted to technological requirements.
