The folded tubular heater is designed with a compact bent structure, providing a larger heating surface and enhanced heat transfer efficiency. When current passes through the resistance wire inside, the heat generated is conducted through high-purity magnesium oxide insulation powder to the metal sheath surface, and then efficiently transferred to the heated medium such as air, liquid, or solid components. With its folded configuration, the heater can deliver higher power density within limited installation space, making it ideal for applications requiring concentrated heating or compact layouts.
This heating tube features a robust construction, strong mechanical strength, long service life, and stable performance. Its flexible installation options allow for various combinations and arrangements, making it convenient for system integration and maintenance. The folded design not only saves space but also improves heating efficiency, widely used in mold heating, plastic machinery, liquid heating, air heating, and other industrial equipment.
Lengths, voltage, power, and bending shapes can be customized according to customer requirements. With advantages such as high efficiency, reliability, and durability, the folded tubular heater provides a cost-effective and dependable solution for diverse industrial heating applications.
