Customized Ribbed Tubular Heating Element is a highly versatile and durable heating solution designed for efficient air and non-corrosive gas heating in industrial applications. Constructed using WNH robust tubular elements, these heaters feature tightly wound spiral fins that significantly increase convective surface area, enabling faster heat transfer and higher power density in compact spaces. The fin spacing and size are meticulously tested and optimized for peak performance, while furnace brazing bonds the fins securely to the sheath, enhancing conductive efficiency. This design lowers sheath temperatures, prolongs heater life, and allows for higher wattage levels within the same flow area.
For high-temperature or corrosive environments, stainless steel fins securely wound on alloy sheaths are available, ensuring reliable operation under demanding conditions. Steel finned units can also be equipped with protective coatings for mildly corrosive or high-humidity applications. Compared to open coil heaters, ribbed tubular elements are safer, minimizing fire risks from combustible particles and electrical shock hazards. Their rugged construction ensures increased service life and reduced maintenance, making them ideal for continuous operation.
These heaters are widely used for forced air heating applications, such as heating premises, closed drying circuits, charge benches, and more, operating efficiently up to 200°C (with airflow of 4 m/sec). They are also suitable for conduction, convection, and radiation heating in stoves, industrial ovens, drying cabinets, air conditioners, and other systems. Capable of withstanding temperatures up to 750°C (1382°F), they can be customized into unique shapes to meet specific industrial needs.
