The cartridge heater from Shanghai Pollux Group Co., Ltd. is a tubular heating element constructed with a nickel-chromium alloy wire wound around a magnesium oxide core rod. The design incorporates high-purity magnesium oxide powder as insulation between the heating wire and the outer sheath, ensuring both thermal efficiency and electrical safety. The air inside is compressed to enhance durability, resulting in a robust and reliable product.
This heater stands out for its small diameter, which can range from 3mm to 35mm, and its length, which is not limited and can extend up to 2000mm. It delivers high power output, achieving surface watt densities of 20 W/cm² or even 60 W/cm² in specialized configurations. The heater’s simple structure, high mechanical strength, and long service life make it ideal for demanding industrial applications where space and efficiency are critical.
Industrial buyers choose this heater for its versatility, as it can be bent into various shapes and easily disassembled for maintenance. It is commonly used in machinery requiring precise, localized heating, such as in the plastics, packaging, and food processing industries. The supplier offers customization options for fixed accessories or thread structures to meet specific installation needs.
