1What is the material that is used as the basis for most heating elements?
Nichrome wire
2Describe the construction of a calrod element?
Coil of nichrome wire insulated within a metal tubular sheeth
3Why is the calrod element the most popular type of element used?
Can be bent into any shape and is virtually unbreakable
4What is the purpose of the cold pin in a calrod element?
To keep the mernimal commentions from overheating, and to determine the part of the heater that does get hot
5What are some of the materials that can be used to make the sheath for calrod elements?
Aluminum, steel, monel
6Why is the watt density of an element an important consideration in its design?
It determines how hot the element will get per inch
7Elements with the higher watt density are used in what applications?
Immersion
8Why must immersion elements always be submersed in liquid when energized?
The high watt density will melt the sheeth
9An immersion element that has the sheath split apart and swollen indicates what?
The unit ran dry or "dry fried"
10What are stainless steel calrod elements normally used for in our foodservice industry?
Fryers
11Do all stainless steel elements appear shiny, like you would normally expect stainless steel to appear?
No, some are black
12What does the annealing process to a stainless steel elements do to its appearance?
Turns it black
13Failures of calrod elements used on grill and ranges can often to attributed to what problem?
The elements are not clamped tightly to the griddle plate
14What usually causes the terminal connections to burn off the end of an element?
Loose or burned wire connections
15Describe an element platen?
A calrod elements molded into an aluminum or steel blaock to better spread the heat
