ECONOMICAL:Nesdra chooses high temperature Fe-Cr-Al heating wire for its standard series furnace electrical heaters, with additional elements to increase its high-temperature resistance. Compared to HRE heating wire and KANTHALTM heating wires, the standard 0Cr21Al6Nb wire provides lower working temperature, but shall be enough for many heat treatmeng companies who works at medium and low process tempertures. For them, Nesdra standard heaters is an economical solution. We strongly recommend customers choose Nesdra Supreme Heaters or even KANTHALTM heaters whose process temperatures are high.

TRACEABILITY:We know that the surface quality is critical to the quality of the heating elements, therefore we pay extra attention to minor details during production that may cause any defects on the wire: Not only are wires carefully checked during incoming inspection, but also we ensure that no metal tools are allowed during whole production to protect the wire from any scratches. With the serial numbers marked on each of our heaters, we can trace back to historical production records throughout warranty period and improve in case we discover issues in the field.

following conditions should be met to allow warranty to be granted :

  • the heaters have to be only used together with Nesdra radiation tubes.
