The FBT series is a closed-circuit cooling tower for furnace coil water, power-supply water and capacitor water. The process water stays inside a coil and does not touch outside air, so the furnace circuit stays clean.

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.
Key features
- Closed loop: no scaling inside the furnace cooling circuit
- No open pond on the process-water side
- Antifreeze duty for cold climates
- Low-power spray pump and fan, with speed control on the tower
- Catalog models from the FBT-60 / FBT-100 class upward
Construction
- Heat-exchange coil, spray section, fan, basin and the furnace pump set.
Working principle
Hot furnace water passes through the tower coil. Spray water and air take the heat away. The furnace water returns at the temperature the coil and the power supply require.
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.

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.
