The right angle (RA) element is a heating element that has two cold ends, welded at right angles to the opposite ends of the hot section. The maximum recommended furnace temperature is 1425ºC (2600ºF). The element is manufactured of high density recrystallized silicon carbide. The two cold ends are low resistance silicon carbide. The diameters available range from 13 to 54mm and hot zone lengths up to 1500mm and cold ends up to 480mm long.
The RA element is ideal for launders where terminal connections are on the top of the furnace. The RA element has support holes in the cold end so the element can be installed with the cold ends through the roof. Cotter pins and washers are included with each element.
