Electrical heating is a process in which electrical energy is converted into heat. Electric current when passes through the element encounters resistance, which leads to the heating of the element. From hair drier to toaster to industrial smelting, electric heating element helps to get the desired temperature. Commercial heaters are an economical solution for heating large areas like construction sites. The electric heating elements are applied for space heating, cooking, and water heating and industrial processes.
Common types of elements: Common electric heating elements include, Band heaters- mainly used for indirect heating, Cartridge heater- used for heating oil, sugar or air. Mainly used for melting plastic pellets, Circulation heaters- used for heating flowing gases or liquids, Radiant heaters- used to transfer energy from a heat source to an object.
Besides these, there are a number of other heating elements available these days. The commercial and warehouse heaters are also available. These may operate as electric, propane or natural gas heaters. Many commercial heaters are used indoor to heat very small to large spaces.? Commercial heaters include Salamander- burner producing 1850O of intense heat, and Bed bud treatment- it deals with infestations. It is done with the help of steam cleaning or heat treatments.
Immersion heaters, VLE Fan heaters, tubular heaters are few industrial heaters commonly used. The immersion heaters are used for heating gases and liquids. The VLE Fan heaters are designed for harsh weather conditions. The tubular heaters on the other hand are the most versatile one.
The industrial heaters have uniform heat distribution and long life. These can heat elements according to desired shape and size. The heaters are generally fitted with an integral high limit safety cut out and thermostat unless otherwise required. Heater treatment enclosures are also incorporated.
How to choose a heating element
Before choosing a heating element it is necessary to assess the heating system. The unit specifications are important in order to handle the power requirements. The heating elements, needless to say, require proper maintenance.? The Voltage requirement by the electric heaters must be checked beforehand. It is paramount to consider the safety of the equipment.
Electric heaters are very common when it comes to commercial heating. The electric commercial heaters can be either fixed or portable in nature. Before selecting a heater check. Whether pre-heating is required, if the heaters are noisy.
The ambient temperature of the motor should be checked before purchasing heaters. The output of the motor varies with the temperature. The heater element table must be checked. This gives the calculated service factors of the motors. The tables accommodate motors having service factor 1.15 or more.
Electric heating elements, which need to reach higher temperatures, commonly use ceramics. An industrial heating element is mainly composed of platinum or silicon carbide. The heaters are versatile and are available in various colours, shapes and sizes to match style and environment and of course budget. There are some well known industrial heaters and heating manufacturers in India for quality of their products.
