Electric Heaters

Electric heaters are utilities used for heat generation. The use of electric heaters throughout industry, commerce and consumer products contexts is widespread and varied; the number of different heater configurations and applications grows almost daily. Some heater varieties resemble each other very closely. Band heaters and strip heaters, for example, are distinguished from each other only by the fact that band heaters are usually slightly smaller and more flexible than strip heaters.

The variety of electric heaters on the market is astounding, sometimes with cross over styles and sometimes not. Cartridge heaters sometimes qualify as immersion heaters, but not always. Sometimes, a heater’s name is descriptive of its use, as is the case with drum heaters. In other cases, a heater’s name is descriptive of its configuration, as is the case with tubular heaters. Some heater terms can be used interchangeably; air heaters and duct heaters are both used in HVAC filter systems to heat air, though a free-standing space heater could also be considered an air heater but not a duct heater. Both could be described as circulation heaters, though some circulation heaters are used to heat liquids in a containment system. All of these heaters can be considered process heaters, depending on their use, and they are all likely to feature wire or coil heating elements with ceramic, mineral or other insulation material. Despite the seeming interchangeability of terms and the confusion it can cause, each variety contributes to an important industrial process or commercial utility as well as some purposes in the context of consumer products.

Cartridge Manufacturers

Cartridge Heaters - Thermal Devices Cartridge heaters are small, cylindrical electric heaters used to provide localized or precision heat to materials and equipment parts in a variety of settings. Similar to immersion heaters, cartridge heaters are usually inserted into a material to heat the surrounding area; unlike immersion heaters, which are usually submerged in water or other liquids, cartridge heaters are inserted into small holes drilled in metal materials and parts that require internal heat. While capable of providing localized high temperature heating, cartridge heaters can also radiate heat throughout the interior of a material or product.

The type of localized, interior heating produced by cartridge heaters is used to heat specific parts of machinery used in packaging, die cutting, mold forming, hot stamping, labeling, sealing, printing, fluid heating, food service and many other industries. Hot plates, platens, semiconductors, shrink wrap machines and labeling machinery often use internal cartridge heaters to heat specific applicator parts. Plastic and rubber forming processes in particular make extensive use of cartridge heaters and other localized heating systems like strip heaters to assist in the plasticization of materials. Cartridge heaters are available in a wide variety of configurations and compositions to suit the equally wide variety of contexts in which they are applied.

Assembled with similar materials to other types of electric heaters, cartridge heaters are commonly formed from electric coils insulated by ceramic material and encased in a metal sheaths. Insulating materials may also be mica, mineral or fiberglass, depending on the desired wattage and application for the heater. Insulation is necessary between the heating coil and the sheath because contact between the two materials can cause short-circuiting. Sheaths can be constructed from a variety of materials including aluminum, copper, iron, nickel and stainless steel. Some cartridge heater configurations are folded in half, allowing the cartridge to expand as it heats, making contact with the material surrounding it on all sides, thereby providing more effective and evenly distributed heat. Engineers and designers must be extremely precise when using cartridge heaters in equipment, making sure to install cartridge heaters with the proper wattage, heat temperature and oxidation effects in relation to the material in which it will be immersed.

Despite the seeming interchangeability of terms and the confusion it can cause, each variety contributes to an important industrial process or commercial utility as well as some purposes in the context of consumer products.

An electric heater is any electric-powered device used to create heat. They are used in a great variety of contexts. In manufacturing and industrial processing, electric heaters can provide localized heat to an area within a machine to help shape or melt materials, heat liquid tanks, radiate heat through the air or preserve the molten state of a substance. Strip and band heaters as well as cartridge and air heaters are all frequently used for these purposes. In metal, plastic and rubber extrusion, for example, the friction generated as a natural expression of the extrusion process does not always generate sufficient heat to plasticize the materials intended for extrusion. Heaters can be used as a supplement to generate and sustain material plasticization, which contributes to a more efficient process and helps yield a higher-quality extruded product. Heat is an essential part of many other manufacturing processes as well. In packaging, foam fabricating, metal fabricating and food processing industries, cartridge heaters are most often inserted through a custom-sized hole into equipment parts that require localized or high temperature heat. Radiating heaters like immersion heaters and tubular heaters are used to heat liquid or air in water treatment facilities, residential applications, commercial buildings and many other applications.

Every electric heater consists of a few parts that are essential for electrical heat generation. Electric heating is the process by which electricity is converted into thermal energy. An electric charge is usually conveyed by electrons flowing through a medium. When such a medium is connected to an electrically resistant material, the electrons collide with the atomic particles of the resistor, causing them to vibrate. The noticeable expression of that vibration is heat. In the case of electric heating, the resistor is called the heating element. Heating element composition and configuration is variable. Coil heaters can be a simple metal resistor coiled into a spiral shape. Others can feature elaborate configurations and advanced ceramic insulators to maximize heat generation, direct heat distribution and otherwise control the qualities of the heat more effectively. Electric heaters only need heating elements to generate heat, but most of them feature some kind of insulation, and almost all of them feature a sheath of stainless steel, aluminum, nickel or another material to improve performance and extend operating life. Insulation is necessary in many types of electric heaters to retain and absorb electrical energy so that it can be released as heat energy by surrounding coils or materials.

Ceramics are the most common types of insulation, although electric heaters can be fitted with mineral, mica or fiberglass insulation as well, depending on the heater's application requirements. Radiating types of electric heaters transfer heat from ceramic cores or complete heating elements by moving heat through the air with fans, as is the case with space heaters, or through hot air ductwork systems, as is the case with duct heaters. Each application for electric heaters will require a standard for material make-up, temperature capacity and power. Non-electric heating systems can involve coal, wood, gas or water, although most of these alternatives are far less energy-efficient than electric heat generation. Electric water heaters, for example, are more environmentally sustainable and economical than other heating methods. Safety is another crucial concern when purchasing a heater. Different heaters respond in different ways to different environments and applications. Successful industry professionals carefully choose electric heaters based on a foundation of clear knowledge about the operating conditions in which an electric heater will be employed and to what tasks a heater will be applied.

Heating Element Manufacturers

Heating Elements Manufacturers – Hottwatt, Inc. Heating elements are a part of our everyday lives. When we get out of bed and turn up the thermostat, take a hot shower, blow dry and curl our hair, brew coffee or tea, cook breakfast and toast bread we are making use of different types of heating elements. These elements are often hidden within the appliances and equipment we use, and we don't even see them at work.

Electric heating elements are components that convert electrical energy into heat energy. This heat energy can then be used to perform work. Heating elements are made of material sturdy enough to withstand repeated high and low temperature cycles without melting or breaking down. They use radiation, conduction or convection to increase the temperature of the surrounding solids, liquids or gas. For example, the heating element in a hair dryer transfers its generated heat through the air by using convection. The heating elements in a toaster transfer their heat to the bread using radiation in order to evaporate the water in the bread and create toast.

Industrial Air Conditioner Manufacturers

Industrial Air Conditioners Manufacturers Industrial air conditioners are used for cooling in a variety of industrial, manufacturing and warehousing applications. Industrial air conditioners may be window or through-the-wall air conditioners, central air conditioners or ductless air conditioners. Often they must be equipped to cool large areas since industrial settings are rarely small.

Industrial environments range from single rooms within a larger facility to warehouse spaces that are literally several football field length sized rooms. The height of the space also varies, from towering ceilings to allow room for multiple shelving units in shipping warehouses to average height ceilings used for industrial manufacturing factories. This is why industrial air conditioners have numerous models that are utilized by individual companies, depending on the special needs of each. There are also other factors at play, more important then maintaining comfortable work environments for employees. Heat can have very negative affects on industrial machinery and the products stored in warehouse settings. Therefore, the expectations of air conditioners in these industrial spectrums are high, to properly protect the electronic and mechanical integrity of expensive industrial equipment. Agricultural and food and beverage processing plants also require certain temperatures to keep their products from spoiling, as do the warehouses that store the food before shipping. Temperature control is very important to the industrial world.

One type of industrial air conditioner, the window or through-the wall air conditioner is used to cool individual rooms. It is equipped with vents on both sides so that inside air can be brought in and cooled while outside air is blown in and out, acting as a heat sink. In comparison, central air conditioning uses ducts to transport cold air throughout a building. Central air conditioners are useful for maintaining a standard cool temperature in multi-room, multi-story buildings, although they may use more energy since more space is covered. Ductless air conditioners split the difference between through-the-wall and central air conditioning. In this type of air conditioner, an outside unit with the compressor is mounted on an exterior wall, while an inside unit with the evaporator is mounted on an interior wall or ceiling. Multiple evaporators may be attached to a single compressor. As for as being cost effective, ductless air conditioning may be one of the most economical choices for industrial companies. This is because ductless systems are able to target certain areas with heat removal rather then doing it to the whole space constantly, which uses less energy. Also, industrial air conditioners may not be able to be installed in certain spaces with accessible duct systems, which make ductless units even more desirable.
