High-power electric heating elements are high-wattage thermal components primarily used for efficient heating in industrial applications, featuring high power density, rapid heating, and long service life design.
Structure and Materials
Constructed with seamless stainless steel tubes as the outer shell, filled with high-purity magnesium oxide powder for insulation and thermal conduction, and internally wound with spiral resistance wires for electrical energy conversion. Shell materials include options such as 304/316L/310S stainless steel, with temperature resistance ranging from 600°C to 927°C.
Power and Voltage
Power range spans from 60W to 2000W, operating voltages support 24V to 380V, and installation is secured via various methods such as flanges and screw threads. For instance, industrial water tank heating elements utilize flange fixation with power up to 1000W; specialized heating rods for 3D glass bending machines offer 350W power and withstand temperatures up to 927°C.
Application Scenarios
Suitable for heating in industrial equipment such as plastic injection molding machines, 3D curved glass bending machines, pharmaceutical machinery, as well as precision instruments including semiconductor welding equipment and wind turbine generators.
Technical Parameters
Power deviation: ±10% when ≤100W, ±5%~10% when ＞100W;
Insulation resistance: ≥50MΩ in cold state, ≥1MΩ at operating temperature;
Safety certification: CE certified, ensuring stable operation in high-pressure environments.
Usage Precautions
Ensure the heating zone is fully immersed in the medium; dry firing is prohibited. When melting solid media such as asphalt or paraffin, reduce voltage to the rated value before increasing pressure. Surface carbon buildup must be promptly removed to maintain efficiency.
