What is element density?
Element density is the ratio between the wattage of an element and the surface area of that element. The element density is usually 40D, 80D, 120D or 160D and this number reflects the wattage per square inch. For example: an element that is 3,000 watts and has a density of 80D would have a surface area of 38 square inches (3000W/80D). The lower the density, the larger the element and the lower the operating temperature of the element. The lower the operating temperature of the element (per sq. in.), the longer the life of the element.
