Furnace capacitors

Furnace capacitors

In a machine-building industry an inductive heating of metals is widely used by high frequency currents (surface hardening and steel alloying, forging, stamping and rolling, metal melting, soldering, etc.). Furnace plants are used for inductive heating of metals. Inductive heating is connected with a big consumption of inductive current by inductor what stipulates a very low power factor of the plants. To increase power factor of inductive furnace plants the following power capacitors of EEVP, EEPV and EEPVP, KEEPV series are used which are designed and manufactured according to innovation technologies and meet international standards requirements for furnace capacitors.

Application:
to increase power factor of furnace plants with frequency from 0,5 up to 10 kHz.
