Ribbed Tubular Heaters are advanced heating solutions designed to outperform standard tubular heaters by incorporating tightly wound spiral fins that significantly increase surface area. This design enhances convective heat transfer to air and non-corrosive gases, allowing for higher power density in compact spaces such as forced air ducts, dryers, ovens, and load bank resistors. The increased surface area reduces sheath temperatures, improving efficiency and extending the heater's lifespan.
Constructed using WNH ribbed tubular elements, these heaters feature fins mechanically bonded to the sheath through furnace brazing, ensuring thermal conductivity and stability. The optimized fin spacing and size maximize performance while preventing fin vibration at high air velocities. For demanding environments, stainless steel fins securely wound on alloy sheaths are available for higher temperature or corrosive applications. Steel finned units can also be equipped with protective coatings for mildly corrosive or high-humidity conditions.
These heaters are ideal for applications requiring forced air heating, such as premises heating, closed drying circuits, charge benches, and similar systems. They operate efficiently up to 200°C (with airflow of 4 m/sec), making them suitable for a wide range of industrial and commercial uses. With their heat transfer, durability, and adaptability, Ribbed Tubular Heaters deliver reliable and efficient performance in challenging environments.
