What is Serpentine Heaters?

Serpentine heaters are electric heating elements produced in a coiled or spiral shape. These heaters can consist of one or two different alloys and can have cylindrical coils made with the most suitable resistance wires.


Types of Serpentine Heaters

  • Spiral Serpentine Heaters: Metal wire, in tube or cylinder form, is coiled spirally to create a heating element. These heaters are used in many industrial and domestic heating applications.
  • Tube Serpentine Heaters: Heating elements placed inside metal tubes. They are commonly used for heating liquids or gases.
  • Straight Serpentine Heaters: Heating elements made from flat metal plates or wires. Straight serpentine heaters are generally preferred for heating flat surfaces.
  • U-Shaped Serpentine Heaters: Heater with a U-shaped structure designed especially for heating liquids. Liquids heat up as they pass through the serpentine heater.
  • Custom Design Serpentine Heaters: Specialized serpentine heaters designed and shaped for specific applications. For example, there are serpentine heaters designed for industrial ovens or chemical processes.
