RFM water-cooled capacitors are the compensation capacitors for medium-frequency induction furnaces. They correct power factor and form the resonant tank with the induction coil.

Air-cooled RFM capacitors are used where a water circuit is not wanted on the capacitor itself. They serve the same tank-circuit duty on small and medium furnaces.

The capacitor bank is the assembled rack of medium-frequency capacitors, busbar and water manifold next to the furnace. A large single-unit kvar rating keeps the pit small and the high-current loop short.

Every figure in these tables is taken from the factory sheets in the product folder and is written in English. 1 metric ton = 1.102 US short tons. Power-supply ratings can still be negotiated to the customer requirement, as the sheet itself states. American standards are the US specifications normally requested with this equipment.
