HEATING RESISTORS

Heatmasters’ preheat and post-weld heat treatment elements are designed to ensure that the right heating element is used for the right job. The range of standard heating elements is large and it is easy to select the right kind of element in use. The company also manufactures tailor-made heating elements to clients’ specifications.

Quality means longer life
Heating elements are designed to take the demands of the process and working conditions into account. Thirty years of experience in on-site work have shown which constructions and materials are the most suitable.

Construction details
The resistance wire used in heating mats is NiCr 80/20, which is the most suitable for the job. The wire material used in the tails is nickel which does not heat up during the heating process.
In heating elements like types VLV, VLH, VPE and furnace elements, the wire is solid NiCr (80/20) wire in the form of a spiral.

The tail wire and the resistance wire are welded together to form a reliable joint.

Beads in heating elements are high-quality aluminium oxide (Al₂O₃ ; 95 %) ceramic. The material is according to IEC 672 group C-700. Basic colours are: white and pink

Heating elements in which there is a risk of tail breakage are equipped with tail supports. This construction ensures a longer product life.
