About Induction Heaters

Induction heaters use an electrical source to drive alternating current (AC) through a coil to heat metal objects. The passage of current through the electrically conductive coil generates an intense and rapidly changing magnetic field that causes eddy currents to flow through the workpiece. The high frequency used in induction heating also forces AC to flow in a thin layer towards the surface of the workpiece, increasing the effective resistance of the metal object to the passage of the large current. For ferrous materials, the alternating magnetic field inside the coil repeatedly magnetizes and de-magnetizes the iron crystals, causing considerable friction and heating. Heating due to hysteresis loss is greatest for workpiece materials that have a large area. Induction heaters usually incorporate the coil with a tank circuit so that either the current or the voltage becomes sinusoidal. This minimizes inverter losses and radio frequency (RF) interference.

Products & Services Related to Induction Heaters

Band Heaters

Band heaters are ring-shaped heaters that clamp onto a cylindrical object and heat via conductive heat transfer.

Cartridge Heaters

Cartridge heaters are cylindrical devices generally inserted into a heated substance.

Circulation Heaters

Circulation heaters are used to heat moving or circulating fluids.

Cylindrical Ceramic Fiber Heaters

Cylindrical ceramic fiber heaters consist of an iron-chrome-aluminum (ICA) heating element and a thick layer of ceramic fiber insulation within a cylinder-shaped housing.

Drum Heaters

Drum heaters are used to heat containers of viscous materials. They can be wrapped around or placed inside containers that hold substances such as wax or grease.

Duct Heaters

Duct heaters are used to heat moving gas streams.

Explosion Proof Heaters

Explosion proof heaters are constructed with housings that can withstand explosions, protecting the materials being heated. This classification may also include housings, which can withstand sparking and flames.
