The furnace water-cooling system ties the coil, the yokes, the power supply and the capacitor bank to the cooling tower. It is designed with the furnace, because a melt cannot run without water.

Key features
- Separate circuits where coil water must stay cleaner than spray water
- Pumps, valves, heat exchanger or closed tower, and temperature switches
- Interlocked with the power supply: low water stops the furnace
- Laid out for the pit, the capacitor room and the tower together
Construction
- Pumps, closed tower or plate exchanger, headers, flow switches and emergency water.
Working principle
Each cooled part has a flow and a temperature limit. The supply will not stay on if coil water or capacitor water is lost.
Applications
Steel, cast iron, stainless steel, copper, aluminum, aluminum alloy, brass and other non-ferrous metals.
Complete system integration
This equipment sits in the same line as the power supply, the capacitor bank, the induction coil, the magnetic yoke, the furnace body and the cooling system. A quotation can cover one item or the full line.
Customization
Capacity, voltage, frequency, dimensions and connection layout can be made to the furnace design. Send the drawing or the duty data below.
Catalog sheets
Questions before a quotation
Can the rating be customized?
Yes. Capacity, voltage, frequency, tube size and connection layout follow the furnace drawing and the metal.
What do you need for a quotation?
Furnace capacity, metal, melting temperature, melting rate, working hours, input voltage, frequency if known, tilting method and cooling-water conditions. A drawing helps.
Do you supply a single machine or the complete system?
Both. A spare coil, yoke, capacitor or cooling tower can be quoted alone. A new foundry line is quoted as a complete system.
Which metals can be melted?
Steel, cast iron, stainless steel, copper, aluminum, aluminum alloy, brass and other non-ferrous metals. The lining and the frequency follow the alloy.
Will you confirm the catalog numbers before manufacture?
Yes. The sheets on this page are the factory catalog for selection. The quotation states the rating that will be built.
