How is a calrod element constructed?

A calrod element is constructed using a coil of nichrome wire that is insulated within a metal tubular sheath. This construction is essential for a few reasons. First, nichrome wire is a common heating element material due to its high resistance and ability to withstand high temperatures while providing efficient heat generation.

By insulating the nichrome wire within a metal tubular sheath, the design ensures that the heat generated by the wire is effectively transferred to the surrounding environment or food product while also being protected from damage. The metal sheath serves as a stable structure that can also help with heat distribution and safety, preventing the risk of wire exposure to moisture or contaminants that could lead to short circuits or failure.

This construction method allows for a high power density and effective thermal response times, making calrod elements suitable for various applications in commercial food equipment, such as ovens and cooktops.
