Coil Heaters: Types and Uses

Heater coils are mostly resistive elements that consume whole active power and dissipate the same as heat. It uses the Jule effect (H= I2 x R x t), in order to produce this heat. Overheating is the main cause of heater failures since every heater has a certain power dissipation capability beyond that it can fail. Knowing the options available and the common uses for each electric coil heater type can help you, as a businessperson, choose the best coil heater for your needs. Let’s look at various kinds of coil heaters and their uses. 

  • Flat coil heater: This kind of heater is relatively simple in design. It is a heater that is wound around a flat coil. Thus, it is easy to place inside a variety of objects due to this flat shape. Uses: This kind of heater is most often used in injection molding machines for plastic and metal of varying sizes. Warning: Do not use this coil for temperatures exceeding 1000 F for extended periods of time.

  • Maxi coil heaters: These have larger physical dimensions (10mm wide x 3.8mm high) and are suitable for increased wattage and robust working condition requirements. Their bigger size makes them ideal for large injection molding machines or large die casting machines and metal molding equipment.

  • Axial clamp heater: Axial clamp mini coil heaters are a proven performer for high cavitation applications including pre-forms, caps and closures, and razors. This kind of heating element is suited for high caution applications.

  • Formable coil heater: As the name implies, a formable coil heater is a heater that can conform to a variety of shapes without damaging the heating elements contained within. Because this element is so flexible, it is excellent at heating challenging objects.

  • Round coil heater: Round coil heaters are simple in design and are capable of heating a variety of tricky objects.
