Tubular heaters are the most versatile and widely used industrial heating elements, designed for direct heating of air, liquids, solids, and surfaces. Built with a NiCr resistance wire insulated with high-purity magnesium oxide and encased in a metal sheath, they provide efficient heat transfer, durability, and uniform performance.
Available in straight, bent, or custom-formed shapes, tubular heaters are suitable for immersion, radiation, or conduction heating. Their adaptability, robust design, and long service life make them the standard choice for a wide range of industrial and commercial applications.
