1200 1400 Heating Elements for furnaces

Above 1200 C has always presented issues for the standard Fe-Cr-Al heating elements. For that reason, Kanthal created APM wire. At MELLEN, we have done extensive testing of the different combinations of heating element element wire and we have discovered that, although APM wire is a real improvement over standard Fe-Cr-Al, its really just half of the equation to operation at 1300 C. The current industry standard method of taking a regular ceramic clamshell or flatplate and stuffing APM wire in it instead of the normal Fe-Cr-Al and calling it a 1300 C element, just doesn't cut it. Here at MELLEN we have discovered that small diameter APM wire (1.0 mm - 1.5 mm) gives only a marginal improvement to the life at elevated temperatures. That why when you come to us and ask us for a standard clamshell or flatplate made from APM wire, you will notice that we quote it as a 1250 C element and recommend that you keep the operating temperature at or below 1200 C for increased life. It is this EXACT issue that prompted us to begin research into extending the life of our standard 1300 C heating elements. What we have come up with are three distinctly different elements, each with its own advantages and disadvantages - Our series 12.5C and 12.5V, standard APM wire 1.5 mm or smaller in ceramic holders or our special vulcan design, Series 13VHD, Heavy Duty APM windings (2.0 mm or larger) in our special Vulcan series holders or finally Series 13VREH, an extremely thick, specially designed wire specifically made to radiate heat better at high temperatures. With these three designs MELLEN has covered the range of people who need to go only occasionally above 1200 C all the way to people operating at 1300 C constantly. If you fit into that range, then read on below for specific descriptions of the three different series of elements, as well as their advantages and disadvantages.

MELLEN can raise your operating temperature in more ways than one, the hotter the better.
