A Medium Frequency (MF) Water Cooled Capacitor is a specialized high-current capacitor designed for use in medium frequency induction furnaces. It plays a vital role in the LC resonant circuit, working with the induction coil to achieve efficient energy transfer, power factor correction, and stable furnace operation.

The capacitor compensates the inductive reactance of the furnace coil and helps maintain resonance at the operating frequency. This reduces reactive power demand, improves electrical efficiency, and ensures uniform heating in melting and heating applications.

• Induction melting furnaces (steel, iron, copper, aluminum)
• Billet and bar heating systems
• Heat treatment and forging lines
• Induction brazing and welding

• Dielectric: Metallized polypropylene (PP) film, low loss
• Cooling System: Integrated water-cooled tubes for direct heat dissipation
• Casing: Welded aluminum/stainless steel, hermetically sealed
