Resistance heating element A heating element converts electrical energy into heat through the process of resistive or Joule heating. Electric current passing through the element encounters resistance, resulting in heating of the element. Unlike the Peltier effect, this process is independent of the direction of current flow. Nichrome Most heating elements use nichrome 80/20 (80% nickel, 20% chromium) wire, ribbon, or strip. Nichrome 80/20 is an ideal material, because it has relatively high resistance and forms an adherent layer of chromium oxide when it is heated for the first time. Material beneath this layer will not oxidize, preventing the wire from breaking or burning out. Resistance wire: Metallic resistance heating elements may be wire or ribbon, straight or coiled. They are used in common heating devices like toasters and hair dryers, furnaces for industrial heating, floor heating, roof heating, pathway heating to melt snow, dryers, etc. The most common classes of materials used include:Kanthal (FeCrAl) wires , Cupronickel (CuNi) alloys for low temperature heating Scarlet Helical Coil Heating Elements Scarlet Helical coil heating elements are manufactured in continuous coils or around ceramic spools and are adaptable to many types of industrial ovens and furnaces. They provide a broad power density range for application flexibility. Furnace downtime associated with element maintenance is reduced because elements are replaceable in sections. Furnace Type: Carburizing, hardening, glass annealing furnaces and dies casting machines are equipped with helical coil heating elements. Benefits: Easily configured to furnace chamber , Wide temperature range Multiple mounting options , Can be replaced in sections Long service life , Quick delivery of any size order , Downtime-reducing stocking program Primary Element Alloys: 80/20 and 70/30 Ni/Cr , Fe/Cr/Al Maximum Element Temperature: Ni/Cr: 2100° F (1150° C) ,Fe/Cr/Al: 2280°F (1250° C) Power Rating: As required.

The elements can be provided in almost any length but the standard dimensions available are 68 to 170 mm (2.6 to 6.6 inch). These heaters can be used as standalone elements or inside radiant tubes. Because of the ingenious design, Bundle rod heating elements deliver a much higher power than conventional cartridge heaters. In combination with radiant tubes, a system is created which delivers high power, is rugged, versatile and needs low maintenance. Designed & manufactured in low voltages for faster heating in order to achieve temperatures quickly, these heaters can be mounted horizontally or vertically. Either NiCr alloy (Mara Nicro)or FeCrAl alloy(Mara FeCrAl) can be used as heating element. For temperatures up to 2100°F (1150°C), Austenitic (NiCr) alloy (80/20 or 70/30) and for temperatures up to 2597°F (1425°C), Ferritic (FeCrAl) alloy can be used. Superior Power Output Bundle rod elements, with a higher power output, leads to major saving in cost and maintenance. Also when combined with radiant tubes, they give highest power rating (up to 100 kW) as compared to any other heater. Easy installation Due to its ruggedness and versatility, bundle rod elements are easy to install and replace. Compatibility with radiant tubes allows installation to be either horizontal or vertical depending on the application. Easy repair and high temperature performance gives it an edge over others. Custom designed for the voltage and wattage required, bundle rod heaters are used in heat treat furnaces and die casting machines to molten salt baths and incinerators.

Chapter 5 Historical introduction Summarized history of air heating and sheathed heating elements Copyright: Jacques Jumeau 1st edition 2015/11/26 Copy is allowed, provided you cite the origin: Ultimheat Museum 1 Update 2019/02/20 Historical introduction Summarized history of air heating and sheathed heating elements The invention of sheathed heating elements comprising a metal tube swaged around a coiled heating wire, and which is insulated by compressed magnesia, was an essential step of the electrothermics development. Thanks to their mechanical strength, impermeability and resistance to corrosion, these are the most professional heating technical solutions. The appearance of these heating elements, now universally used, was the result of a combination of different advanced techniques of the early 20th Century. Over the last two decades of the 19th Century, the emergence of electric heating had revealed the need to find reliable solutions for converting electricity into heat. The first electrical heaters were platinum wires (inherited laboratory equipment), nickel silver or even iron. Research carried on resistive elements with greater resistivity and good temperature resistance. On October 12, 1878, St. George Lane Fox-Pitt filed patent in England 4043, in which he developed the use of electricity for lighting and heating. This patent, based on the use of platinum filaments, was not followed for heating but it was the basis for the development of electric bulbs. In 1884, French Henri Marbeau, a pioneer in the manufacture of Nickel in New Caledonia and France, founded the company "Le Ferro-Nickel'' in Lizy sur Ourcq".

  • On the Electrical Behaviour of Metal Mesh Heating Elements for Resistance Welding of Thermoplastic Composites
    This is an Accepted Manuscript of an article published by SAGE in The Journal of Thermoplastic Composite Materials on 2015, available online: DOI: 10.1177/0892705712475012 CHARACTERISATION OF A METAL MESH HEATING ELEMENT FOR CLOSED-LOOP RESISTANCE WELDING OF THERMOPLASTIC COMPOSITES Irene Fernandez Villegasa, Harald E.N. Berseea aStructural Integrity and Composites, Faculty of Aerospace Engineering Delft University of Technology, Kluyverweg 1, 2629 HS Delft, The Netherlands Corresponding author: Irene Fernandez-Villegas, T:+31152789745, F: +31152781151, [email protected] ABSTRACT Resistance welding is one of the most suitable and mature welding techniques for thermoplastic composites. It uses the heat generated at the welding interface when electric current flows through in a resistive element, frequently a metal mesh. Closed- loop resistance welding relies on indirect temperature feedback from the weld line for process control. Its implementation is more complex than the most common open-loop welding, but on the contrary it does not in principle require the definition of processing windows for each welding configuration and it allows for constant-temperature welding. The temperature at the welding interface can be indirectly monitored through the resistance of the heating element. The relationship between resistance and temperature, expected to be approximately linear for a metal mesh heating element, can then be used to translate the welding temperature into a target resistance value for the process control routine. Despite the apparent straightforwardness of this procedure, the research results presented in this paper prove that different types of characterization tests yield different 1 This is an Accepted Manuscript of an article published by SAGE in The Journal of Thermoplastic Composite Materials on 2015, available online: DOI: 10.1177/0892705712475012 resistance versus temperature relations for a metal mesh heating element, which can lead to significant temperature deviations when used in closed-loop processes.

  • How to Determine If an Electric Heater Is Good Or Bad Using an Ohmmeter By: Admin - November 06, 2020
    How to Determine if an Electric Heater is Good or Bad Using an Ohmmeter By: Admin - November 06, 2020 (abcimg://ohm%20meter) Your Watlow® electric heater (/en/products/heaters) is designed to hold up to years of use in some harsh industrial conditions. Over time, the electric insulation may deteriorate and you may experience performance issues. Both heaters and power and temperature controllers are subject to performance issues, so it is important to inspect both for signs of wear and breakdown. Here we will cover all you need to know about ohms, ohmmeters and signs that your electric heater needs to be repaired or replaced with a new Watlow unit. Understanding ohms Before you check your heating products to see whether they are working effectively, it is important to understand ohms, watts, volts and amps. These electrical units allow you to compare the output of various heaters and identify signs of an inefficient or failing heater. According to Ohm’s Law the current is equal to the voltage divided by the resistance. This can also be expressed in the following equation: I = V/R (where I = current, V = voltage and R = resistance) The current of a thermocouple (/en/products/sensors/thermocouples)or other electrical device is measured in amps, the voltage is measured in volts and the resistance is measured in ohms. A high level of resistance is necessary to transform electrical energy into heat energy. The thickness, material and other factors of the conductor affect its efficiency and available temperature range. Resistors are made of materials that have a high level of electrical resistance.
