Thick Film Tubular Heaters

Thick Film Tubular Heaters, also called Thick Film Cylindrical Heaters, are high-efficiency heating devices that use tubular stainless steel or ceramic as the substrate, applying thick film heating technology to precisely coat the surface with conductive materials, heating resistors, and insulating materials, which allows them to convert electrical energy into thermal energy through the Joule heating effect to provide stable and precise heating, achieve high thermal efficiency at low power, ensure even heat distribution, reduce the risk of overheating, and deliver durable performance.

Thick Film Tubular Heaters have several standout characteristics. First, their stainless steel or ceramic substrate materials provide strong durability in high-temperature and corrosive environments. The thick film technology enables excellent thermal efficiency, ensuring that most of the input energy is converted into radiant heat (up to 92%). They typically operate within a temperature range of 300°C to 700°C, emitting infrared wavelengths that are ideal for various applications, especially where temperature control and energy efficiency are critical. Additionally, the design of these heaters helps prevent localized overheating, ensuring uniform heating.

Thick Film Cylindrical Heaters are widely used in multiple fields that require precise heating. In the food industry, they are employed for heating and baking bread, warming food, and maintaining temperature. They are also used in coating curing processes and plastic softening or welding. In the medical field, these heaters are found in heating systems and experimental equipment. In aerospace and automotive industries, Thick Film Tubular Heaters are ideal for high-demand environments due to their efficiency and reliability. By providing a stable heat source, they meet the needs of various industrial and commercial applications.
