Frequently Asked Questions
What is the function of an induction heating capacitor?
Induction heating capacitors provide the necessary reactive power required to maintain electromagnetic fields in induction furnaces. This optimizes the power system factor and increases overall energy utilization efficiency.
What cooling methods are available for these capacitors?
We offer water cooling, air cooling, and natural cooling methods based on your specific operational and environmental requirements.
What are the water quality requirements for water-cooled capacitors?
The cooling water must be soft water, free of impurities, and maintain a PH value in the range of 6 to 9 to prevent blockage or corrosion.
Can Flair customize the capacitor configuration?
Yes, we provide customized solutions including options for insulated or non-insulated cases, pressure switches, internal discharge resistors, various water tube designs, and custom terminal connections.
What are the temperature limits during operation?
The ambient temperature range is -20°C to +50°C. For water-cooled configurations, the inlet water temperature must not exceed 35°C, and the outlet water temperature must not exceed 45°C.
What case materials are used for the capacitors?
Depending on the specifications, we use high-quality Aluminum alloy, stainless steel (with a typical thickness of 3mm), or brass to manufacture the capacitor cases.
