Strip and Finned Strip Heaters are versatile surface and air heating elements, engineered for applications requiring uniform heating, durability, and high efficiency.
These heaters consist of a NiCr resistance wire wound inside a ceramic core, encased in a metallic sheath for protection and effective heat transfer. For higher airflow applications, continuous metal fins are furnace-brazed to the sheath, significantly improving convective heat dissipation and enabling compact designs with higher watt densities.
They are widely used in plastic machinery, ovens, dryers, load banks, hoppers, and conveyors, offering excellent thermal performance, mechanical strength, and long service life with minimal maintenance.
