What Does A Heater Coil Do?
An appliance that heats air or water called a heater coil. The heater coil, which is usually electric, works as a resistor and heats up as the electric currents passing through it. The same kind of wire that is used in a heating coil is also utilized in typical domestic toasters. A rheostat switch governs how much heat the heater coil emits. Electric clothes dryers, ovens, and hot water heaters are a few examples of equipment that employ different types of heater coils to generate heat.
Heat is transferred to the target medium via electric heating coils from the heater. The heating element known as a coil is a part of the actual heating unit. A current of electricity is produced by the heater and flows into a coil, where it is converted into heat energy. To heat a medium, it can either be submerged directly in it or heated by heating an area that is not enclosed.
Types of Electric Heating Coil Elements
Depending on the purpose of the heating coil, there is an option to choose between covered or opened. These are the two major classifications of heating coil elements; covered and open. In summary, open heating coils are mainly used for indirect heating, while covered coils work best for any direct heating purpose. Even though open coils are economically affordable and very efficient to perform their purpose, they aren’t flexible enough for several applications.
- Covered Electric Heating Coils
Not all heating applications need exposed components. For instance, open coils are vulnerable to deterioration and corrosion during direct heating activities. Heater coils have a protective covering to stop this from happening. This sheath lowers the dangers of electricity and fires while shielding against the weather.
When selecting an immersion heater, the sheath material is critical. The qualities of the intended media should be taken into consideration while choosing the material. For instance, an Incoloy sheath would probably be used in severely corrosive conditions because of its corrosion resistance.
- Open Electric Heating Coils
The components are visible in coils with open ends. They have quick heating periods since there is no requirement that heat be supplied through a protective covering. Minimal-cost, simple-to-replace parts make them low maintenance. The exposed components have the disadvantage of being more prone to damage. Open coil elements are mainly used in devices like ovens, metal heating, forced air and the likes.
