Cartridge heater often considered as component heater has a heating coil wound on a ceramic core and are cylindrical-shaped, heavy-duty Joule heating element. Electricity flows through coil when a two or three-phase voltage is applied. The electricity heats the coil and, subsequently, the cartridge sheath. The watt density (in Watt/inch2) depends on the number of spirals or turns per inch. The sheath comes in contact with the surface being heated. Insulation in the cartridge heater ensures that the heating wire never comes in contact with the sheath and protects the sheath from melting in case of any mishap. The leads that come out of the heater terminal have metal conduit, or silicon sleeves to protect from high temperature. Lead wires are often fiberglass or silicon rubber. 

Ceramic band heaters are medium-to-high temperature heaters that can deliver up to 1600°F (870°C). The heating element (Nichrome wire) is embedded in a flexible outer wall made of interlocking ceramic tiles, assembled like a brick wall. A ceramic fiber insulating mat and a stainless steel/ Aluminized Steel jacket cover this assembly. This makes them flexible, highly efficient, prevents heat loss and reduces electrical consumption by 20%. An energized ceramic heater that operates at 1200°F internally will have around 400°F on its outside shell. These durable heaters have versatile configurations which allow selection of clamping mechanism, terminal styles, holes and cut outs and perforations. Uniform heat distribution is an added advantage of ceramic band heaters. Limitations on the width of these heaters within a certain incremental range of sizes, is due to ceramic tiles that are available in specific lengths. Ceramic Band Heaters afford customers a means to heat large cylinders from intermediate to high temperatures without concern of failures due to "Hot-Spotting". A layer of thermal insulation reduces ambient heat loss and power consumption.

A blower assembly is used to distribute air in various kinds of equipment. It is commonly seen in cars, furnaces, and home appliances. During forging or furnace operation, air is the utility that should be available at all time in order to ensure a smooth and standardized operation.

Supplying air manually will reduce productivity and more man hour to accomplish a given task. 

Mica band heaters offer efficient and economical heating solutions to pipes and tubes that require external indirect heating. These heaters are used to heat-up the external surface of drums or pipes for a gradual heat transfer. A mica core surrounds the precisely wound heating element, producing a thin, efficient heater. The mica core is enclosed in a continuous corrosion resistant sheath and formed. All full mica band heaters are designed with closed ends to protect against contamination. The maximum sheath temperature is 800°F and is used mainly in plastic industry. Terminal boxes can be provided that protect terminations and also have the option of temperature controllers to help regulate applied heat. Mica is used as it provides exceptional insulation, dielectric strength and heat transfer capability for long heater life. Insulation is required to direct the heat to the application, avoid heat loss and slow heat-up time. In order to maintain a balance between the insulating characteristics of mica and the ease of heat transfer from the heating core, the thickness of each mica layer is cautiously selected. Various terminations are available with mica band heaters keeping in mind the diameter, width, voltage, operating temperature and cost. Several types of dimension, wattage, voltages and material are available to suit different applications.

Famously known as “flexible heaters”, silicone rubber heaters are composed of fiberglass reinforced silicone rubbers that are rugged, moisture and chemical resistant, flame retardant, have high dielectric strength and are non toxic. Wire or etched foil heating circuits are positioned between two “wafers” of silicone which provides flexibility and strength. Design versatility permits zones of higher or lower heat concentration as needed. They are capable of flexing and will conform to contoured surfaces. They can also be pre-formed to complex shapes and can withstand mechanical shock and vibration. Designed to meet the requirements of various low and medium temperature applications, they improve heat transfer; speed warm ups, and decrease wattage requirements. The silicone Fiberglass-reinforced silicone rubber gives the heater dimensional stability without sacrificing flexibility. Thermostats or RTD can be mounted for temperature control. Teflon lead wires can exit any location to make suitable connections.  Different mounting methods such as pressure sensitive adhesive, field applied adhesive, Velcro etc. are available according to the requirement.

Duct heaters are heat transferring devices which are an assembly of heating elements mounted in a frame or duct. Preferably used for non-pressurized air-heating systems, there are three types of duct heaters available: open coil, tubular or finned tubular heating elements that are either flanged or inserted in the duct. The individual elements are removable through the housing of the assembly, which eliminates the need to pull the complete heater from the ductwork. This reduces downtime costs because the heating elements can be replaced individually. Being the most easily adaptable heating solution, they are easily installed in applications requiring a wide range of temperature versus air flow combinations and offer greater reliability, energy efficiency, quicker response time and reduced infiltration from the air steam. Duct heaters can be equipped with a temperature control system and wired in various power configurations

Bobbin heaters are mainly used for direct heating of air and indirect heating of liquids and gases where the element is fitted into a pocket in the process tank or system so that the element may be replaced without draining down the system or vessel. Highly energy efficient as 100% of the heat is generated within the solution. Extensively used for transmission of heat, these heaters are available in various specifications that meet the individual necessity in the best possible manner. Bobbin heaters are made with sheathed and without sheathed material. The sheath material ranges from nickel plated mild steel, copper, nickel plated copper to stainless steel. Resistance wire are supported on refractory insulators and connected to a terminal block at one end. Construction is done with Ceramic link bobbins in either single or 3 phase connections. Thermowell can be provided for accurate temperature sensing or other controls can be provided as well. The element allows easy installation and handling. They are normally manufactured for horizontal mounting, but may be specially designed and constructed for vertical installation.  Designed for any voltage or wattage within manufacturing limits, bobbin heaters are mainly used for low watt density heating and low temperature range. Known to be one o

When the customer demands are such that through-the-wall heaters cannot be installed, portability is required, heaters are to be removed without emptying the tanks, or when there is no access to the liquid medium except from the top, then over the side heaters is the right option. Various shapes and sizes are provided to fit customer dimensions such as,  “ installed-from- the- top” ( L or O shaped) which can easily slide into tanks, vertical loop which are suited for open tank applications or drum heaters for direct immersion in drums. Brackets, risers, legs or junction boxes are used to support the heater if desired. Over the side immersion heaters can be installed in the upper portion of tanks, with the heated portion directly immersed along the side or at the bottom, hence the name. This not only provides ample operating space in the tank, but also allows easy removal and portability. Together with thermowells and control system, this industrial heater, renders practicality and economic feasibility. Mobility is the unique feature of this heater, hence can be used in more than one container, making it a preferred choice for projects. Over the side immersion heaters are the most peculiar heater and stands out among st the immersion heaters.

Known for its versatility, ruggedness and dependability, tubular heaters can virtually be factory-configured to suit a variety of industrial heating applications. Tubular elements are frequently regarded as the foundation of all heating elements. The basic design consists of a resistance wire/coil precisely centered in a metal sheath. This wire/coil is surrounded by magnesium oxide to provide efficient heat transfer from coil to heating medium. Diameters are varied to give customized design and adjustable watt densities for best performance and long life. Bending radius is carefully chosen so as to give optimum performance. Tubular heating elements perform heat transfer by all three modes (conduction, convection and radiation). They are available in both single ended and double ended designs.

Finned tubular heaters are superior to tubular heaters since fins greatly increase surface area, permit faster heat transfer to air and permits putting more power in tighter spaces—like forced air ducts, dryers, ovens and load bank resistors resulting in lower element surface temperature. They are made of up of tubular heating elements and are equipped with electro galvanized steel fins. Mechanically bonded continuous fins assure excellent heat transfer and helps prevent fin vibration at high air velocities. As the surface area is increased and heat transfer is improved due to fins, it results in lower sheath temperature and maximizing of element life.

Open coil heating elements have open circuits consisting of coiled resistance wire (usually Ni- Chrome or FeCrAl) fixed onto a supporting element that heat the medium directly. Termed as the most efficient and versatile while also the most economically feasible solution for heating, these elements have fast heat up times that improve efficiency and have been designed for low maintenance and inexpensive replacement parts. When an electrical current is applied to the wire, it gives off heat. The wire is connected to the control panel which regulates the amount of heat provided by the electric heater and fills the tunnel of the air handling unit. Because of the low mass and fast response time, SSR or SCR switching devices are advisable.  They serve as an indirect solution to decrease watt density requirements and prevent heat sensitive materials from breaking down. The heater can be formed into a compact, coiled nozzle heater supplying a full 360 degrees of heat with optional distributed wattage.

Infrared radiant heaters are electric heaters specifically designed to emit infrared heat, where heating by other means is not ideal. As they rely on infrared energy, they are able to transmit heat without losing it to the outside. Infrared heaters use either quartz element or tubular element that radiate ample heat because it attains high temperatures. Terminals are protected by waterproof housing and are used in conjunction with control panels. If the tubular elements need to be replaced, they are available at an economic cost. Different lengths and sizes are available to meet specifications. Radiant heaters are high intensity heaters and used where high temperatures are necessary. These heaters are simple, economic, easy to clean, cost effective and efficient.

Circulation heater (a.k.a inline heaters) is basically an immersion heater covered by an anti-corrosion metallic vessel chamber. It is accompanied by National Pipe Thread (NPT) screw plug or ANSI flange heater assemblies mated with a pressure vessel. The vessel is mainly used to provide insulation to prevent heat loss in the circulation system. An inlet flange transports the fluid into the circulation system, which is then circulated and heated until the desired temperature is reached. The heating medium will then flow out of the output flange at a fixed flow rate decided by the temperature control mechanism. Since it is a compact heating system, the operation is fast and executed in a short time. The heat generated is evenly distributed and the efficiency of the heater is high. Drain valves are also provided to remove leftover fluids or residues. Temperature sensors can be used with any control to achieve the desired temperature range. To manage the liquid flow rate of the heater, the wattage can be manipulated. When the requirement is such that liquid is to be pumped around anyway, a circulation heater is a logical choice.

Screw Plug Immersion Heaters consist of hairpin tubular elements welded or brazed into a screw plug and provided with terminal enclosures for electrical connections. They can be screwed through a threaded opening into a tank wall or vessel. Welding or brazing depends upon the element sheath and plug material compatibility. Depending upon the customer requirement, thermo wells, thermostats or control panels can be used with these heaters to meet the objective of precise temperature control.

As the name suggests, bundle rod heater consists of circular ceramic beads that hold the heating elements. Also known as Tubothal Heating elements or Bayonets, they are designed for long life and maintenance free operation. 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 

Thermocouple is the most universal, expedient, and versatile device used to measure  temperature. It is a sensor that measures precise temperature within a wide range. Manufactured by joining together two dissimilar metals at one end, the thermocouple alloys are usually in the form of wire. A reference junction is also included at the opposite ends of the parent material. By heating or cooling the junction between dissimilar metals, a temperature gradient is produced, which generates a voltage. This voltage is converted into units of heat calibration at the ends of thermocouple wires. The heat generated is converted into useable units that serve as input signals for controllers. Thermocouples are suitable to be used in temperature ranges from -200 to 2316 °C [-328 to 4200] °F. Widely used in high temperature applications, they are less expensive in most cases and can withstand higher temperatures than RTDs. 

Resistance Temperature Detectors (RTDs) are temperature sensors composed of certain metallic elements whose change in resistance is a function of temperature. As the name  implies, these are sensors used to measure temperature by correlating the resistance of the  RTD element with temperature. A small current is passed through pure electrical wire and voltage which is proportional to resistance, is measured and converted to units of temperature. Manufactured by winding a wire (wire wound elements) or plating a film (thin film elements) on a ceramic or glass core, it is sealed within a ceramic or glass capsule. RTDs offer a wide temperature range (-50 to 500°C for thin-film and -200 to 850°C for wire-wound), so selecting the proper element and protecting sheath material is important for functionality. Excellent degree of repeatability, stability and accuracy has made RTDs a common name in laboratory and industrial processes. 

Control panels are, by far, the most reliable and steady solution for controlling the heating system. Choosing a proper controller and panel design helps ensure a trouble free  operation and regulation. In order to meet the demands of various process control applications, control panels can be entirely customized to meet targets. Installing a control panel with the heating system not only maintains the stability and the heat transfer efficiency of the heating system, it also provides safety and prevents issues such as overheating and chemical disintegrations.
