    Technical Parameters

    Iron Cast Heater Characteristics

    Cast iron coil heaters utilize a tubular heating element as the heating element, which is bent into shape. After entering the mold, the outer shell is made of high-quality metal alloy and centrifugally cast into various shapes, including round, flat, right-angle, air-cooled, water-cooled, and other special shapes. After precision machining, they adhere closely to the heated object.
    Cast Aluminum Coils

    Offers a surface load of 2.5-4.5W/cm², with a maximum operating temperature between 300-450°C.

    Cast Iron Coils (Type 1)

    Offers a surface load of 3.5-5.0W/cm², with a maximum operating temperature between 500-600°C.

    Cast Iron Coils (Type 2)

    Offers a surface load of 4.5-6.0W/cm², with a maximum operating temperature between 550-700°C.

    High Efficiency & Uniform Heating: Metal cast coils offer high efficiency and uniform heat distribution. The metal alloy's excellent thermal conductivity ensures uniform heating surface temperature, eliminating hot and cold spots in the equipment.

    Robust Physical Properties: They offer advantages such as long life, excellent thermal insulation, strong mechanical properties, corrosion resistance, and magnetic field resistance.

    Energy Saving: Adding insulation to the outer heat dissipation surface and sintering the inner heat dissipation surface with infrared radiation can save 35% of electricity.
