Strip & Finned Strip Heater

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.

Advantages

  • Energy-efficient design reduces operating costs.

  • Versatility: can be used for both surface heating and air heating.

  • High performance: capable of handling high watt density with uniform heat distribution.
  • Compact design: finned models provide greater heat output in limited space.
  • Customizable: sheath materials, fin height, mounting tabs, and electrical terminations can be tailored.
  • Durability: withstands thermal cycling, vibrations, and mechanical stresses.

Applications

  • Plastic molding machines – platen, nozzle, and die heating.

  • Heating platens & dies for presses and molding tools.

  • Industrial ovens, dryers, and air handling units.

  • Load bank resistors for testing power systems.

  • Hopper, conveyor, and chute heating for moisture removal and material flow.

  • Cabinet and duct heaters for process air heating.

Features

  • Minimal thermal mass enables rapid heating response.

  • Very low pressure drop, ensuring maximum airflow efficiency.

  • Service-friendly design with replaceable coil assemblies.

  • Customizable shapes, lengths, and layouts for ducts, ovens, or chambers.

  • High-temperature insulation ensures long service life.

  • Optional protective guards for added safety in rugged conditions.
