Finned heating tubes are electric heating elements that enhance thermal efficiency by increasing the heat dissipation area through a fin winding process, primarily used in industrial heating scenarios.
Structure and Materials
Composed of stainless steel, modified magnesium oxide powder, high-resistance electric heating alloy wire, and stainless steel heat dissipation fins, manufactured using advanced processes to ensure a dielectric strength of 2000V/min and an insulation resistance >50MΩ. 

Main Features
Efficient Heat Dissipation: The fin design expands the heat dissipation area by 2-4 times, increases surface load by 2-3 times, and improves thermal efficiency by 2-3 times compared to conventional elements.
Rapid Heating: Utilizes high-resistance electric heating alloy wire for faster heating speeds.
Durability: Long service life, supports customized voltage, power, and dimensions, and can be embedded in air blower ducts or static/flowing air heating scenarios.
Application Areas
Suitable for oven and drying tunnel heating (air medium), as well as industries such as mechanical manufacturing, automotive, textile, and food processing.
