Benefits
Our heating resistor elements are easy to use and designed to ensure a long product lifetime. In addition to standard sizes, we also manufacture tailor-made ceramic heating elements to meet your specifications and requirements.
- Long product lifetime
- Beads in heating elements are high-quality aluminum oxide (Al2O3; 95 %) ceramic. The material is according to IEC 672 group C-700.
- Heating elements with any risk of tail breakage are equipped with tail supports to ensure a long product lifetime
- Even heat distribution
- Heatmasters heating elements provide even heat distribution to ensure accurate heat treatment processes
- Custom solutions
- We produce tailor-made elements to meet your specifications and the ISO 17663:2009 standard
- Designed to work
- With half a century of experience working on-site, our ceramic heating elements have been designed using the highest quality standards and feedback from our Wizards of Metal and customers across the globe
- Wire material is nickel, which does not heat up during the heating process
- Easy to attach
- Attaching the heating elements is easy, using a steel band or magnetic clamps. The banding tools (band tensioner and sealer) are easy to use.
