Open coil heaters are a type of electrical heating element that are commonly used in industries and homes. They are made by taking a length of resistance wire and coiling it into a helix, which is then inserted into a housing made of metal or ceramic. When an electric current is passed through the coil, it heats up and radiates heat outwards.

Open coil heaters are compact, efficient and highly adaptable, making them suitable for a wide range of applications. They can be used to heat liquids, gases and solids in industrial processes, or to provide warmth in homes and offices. They are also easy to install and maintain, and can be customized to suit specific heating requirements.
