China Electric Flange Immersion Heater Suppliers - High-Pressure Heating Solutions from a Reliable Factory

Flange-type electric heaters, also known as plug-in electric heaters, are widely used electric heating devices in industrial applications. Manufactured by leading China suppliers, these heaters are ideal for heating and heat preservation in various industries, including petroleum, chemical, food, and machinery. They are highly effective in heating liquids, gases, and low-melting-point metals, making them essential for storage tanks, containers, and pipelines, Our factory produces these electric heaters with a robust construction of U-shaped tubular electric heating elements, which are densely welded to a flange. Utilizing high-quality materials such as stainless steel, nickel-chromium alloy wire, and modified magnesium oxide powder, our products adhere to strict industry technical standards. The core components feature argon arc welding or modular assembly, allowing for the independent replacement of single electric heating tubes, significantly lowering maintenance costs, Offering voltage adaptability of 220V/380V and a power configuration range from 2KW to 10000KW, our electric heaters boast a thermal efficiency of over 90%. Equipped with a built-in PID temperature control system and interlock protection devices, they ensure safe operation by automatically shutting off in case of over-temperature or low liquid levels. Certain models also hold ExdⅡBT4 explosion-proof certification, Our innovative mounting structure design includes movable wheels and vibration-damping components, enhancing deployment flexibility and safety. Trust our China factory for reliable and efficient flange-type electric heaters tailored to your industrial heating needs
