Our Products
SpiroheatEelementsare made from thin walled tubes of Alpha Silicon Carbide, which are dense and resistant to oxidation. Spiroheat Elements operate in most industrial and laboratory Furnaces at temperatures up to 1600oC.
Spiroheat Elements being athin walled, fine grain form of reaction bonded Silicon Carbide, will withstand very rapid heating and cooling cycles, severe thermal shocks, and high Electrical loadings. The Spiroheat range of elementsareavailable in different product forms to suit a variety of heating processes.
Spiroheat Single Ended Elements have all terminal connections at one end. These Single Ended Elements are made of Reaction Bonded Silicon Carbide.
Typical density of Spiroheat Elementsare3.3 Gms./cc 3.4 Gms./cc. These are ideal where Furnace access is limited to any one plane.
One of the earliest Heating Element designs, the enlarged cold ends of the Dumbbell style element were originally made withover sizedcold ends to increase cold end cross section, lowering electrical resistance, thereby lowering cold end operating temperatures.
Modern Dumbbell AlphaRodby contrast, employ anadvancetechnology to keep the terminal ends cool by virtue of the decreased resistivity of the lower resistance cold end material used in the manufacturing process.
Oversizecold ends are therefore no longer necessary, the old style resistance ratio was 1:3, whereas the new DB resistance ratio is 1:40. Maximum temperature is 1550 deg. C. (For Dimensions, Resistance, etc. kindly contact us):
