Metallic Wire Elements
Metallic wire elements are typically the most economical method of heating for industrial applications.
Product Description
Metallic wire elements are typically the most economical method of heating for industrial applications. They are manufactured from a range of resistance heating alloys chosen based on application requirements such as power, temperature, operating atmosphere, and mechanical requirements.
While there are typical standard configurations preferred in the industry, metallic wire elements are often made to fit the unique application where they are used, with detail such as the power output, lengths, number of shanks, terminals and more being highly configurable.

* The typical application temperature when operating in ordinary dry air. The maximum heating element temperature is even higher.
** Maximum power is not possible for every voltage and connection configuration. Having a suitable supply voltage and connection configuration may be necessary to achieve maximum power.
