Heatecx Limited
This high-temperature industrial heater is an indispensable tool in welding engineering and pressure vessel manufacturing. With a capacity to reach temperatures of up to 1050°C, the LH-KJS model is positioned as one of the most robust and reliable industrial ceramic pad heaters on the market. Its main application focuses on the internal heating of large-volume structures, such as spherical tanks and large pressure vessels, where thermal uniformity is critical. The inherent flexibility of its design allows for optimal adaptation to various geometries, making it a versatile solution for custom heaters in large-scale projects.
The LH-KJS Ceramic Pad Heater, also known as an internal frame heater, is a cutting-edge solution designed for high-efficiency industrial heat treatment. This flexible ceramic heating element uses a 0Cr25Al5 alloy heating wire, a nickel-chrome-aluminum material renowned for its exceptional high-temperature resistance and rapid heating capability. Its simple structural design facilitates operation and installation in complex industrial environments. It is the ideal choice for processes demanding precise and uniform weld preheating, as well as for the annealing and post-weld heat treatment (PWHT) of alloy steel components, guaranteeing the integrity and durability of welded joints.
LH-KJS Ceramic Pad Heaters are widely used in various industrial applications requiring rigorous thermal control:
Preheating before welding: Essential for reducing the risk of cracks and improving weld quality in high-alloy materials and considerable thicknesses, especially in the manufacturing of pressure vessels and complex metal structures.
Annealing: Thermal process to restore the ductility and reduce the hardness of metals after welding or cold forming.
Post-Weld Heat Treatment (PWHT): Fundamental for relieving residual stresses and improving the mechanical properties of welded components, prolonging their service life and ensuring operational safety.
Internal heating of spherical tanks and large pressure vessels: Its internal frame design allows for efficient and uniform heating of large volumes, crucial in the petrochemical, energy, and processing industries.
Heat treatment processes in the metallurgical industry: Where precise temperature control is required for modifying material properties.
High Efficiency and Rapid Heating: The 0Cr25Al5 alloy heating strip ensures optimal heat transfer and rapid ascent to the desired temperature, optimizing process times.
Wide Temperature Range: Capable of operating up to 1050°C, making it suitable for the most demanding high-temperature heat treatment applications.
Robust and Durable Design: Built to withstand the most severe conditions in industrial environments, guaranteeing a long service life and consistent performance.
Easy Operation and Installation: Its simple and flexible structure allows for quick setup and disassembly, reducing downtime.
Application Versatility: Ideal for a variety of part geometries and sizes, from industrial pipes to large metal structures.
Improved Weld Quality: Significantly contributes to the reduction of defects and the increase of mechanical strength in welded joints.

We understand that each industrial project has its own requirements. Therefore, we offer customization options for the LH-KJS heaters, adapting to the specific needs of our clients. Although the standard model has predefined dimensions and powers, we can work on made-to-measure solutions for different voltages, powers, and sizes, as long as they remain within the safe operational limits of the material. Our engineering team is available to collaborate on the design of custom ceramic heaters that perfectly fit the geometries and thermal profiles required by your most demanding applications. Contact us to discuss your specific requirements and obtain an optimized industrial heating solution.
The service life of flexible ceramic heaters in an industrial environment can vary significantly, influenced by critical factors such as operating temperature, frequency of use (duty cycles), the quality of the heating material (like the 0Cr25Al5 alloy), and the preventive maintenance regimen. Generally, a high-quality industrial ceramic heater, operated within its specifications and with proper care, can offer hundreds or even thousands of hours of service. Factors such as exposure to mechanical shocks, corrosion, or overheating can drastically reduce its durability. To maximize the longevity of ceramic pad heaters, it is essential to follow the manufacturer's recommendations and perform periodic inspections to ensure optimal operation.
