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

Cartridge Heater
The construction of high temperature cartridge heaters positions a nickel-chrome resistance wire precision wound around a magnesium oxide core. It is inserted into a stainless or Incoloy tube locating the resistance wire close to the sheath. The core is centrally positioned within the tube and filled with magnesium oxide powder. Nickel pins pass through the centre of the core making contact with the resistance wire at both ends. The whole is assembly is highly compacted by a swaging operation and thus ensuring excellent heat transfer to the external sheath. This allows for operating temperatures to 800ºC and high watt densities. One end of the heater is closed with a welded metal end-disc and wire leads exit at the opposite end which is typically closed with a lava seal. A variety of wire leads and lead protection options are available. Heaters can be supplied with internal thermocouples, mounting fittings and many other options.

Inline Heater : SAW HEAT ® inline water heater is composed of an immersion heater covered by an anti-corrosion metallic vessel chamber. This casing is mainly used for insulation to prevent heat loss in the circulation system. Heat loss is not only inefficient in terms of energy usage but it would also cause unnecessary operation expenses. A pump unit is used to transport the inlet fluid into the circulation system. The fluid is then circulated and reheated in a closed loop circuit around the immersion heater continuously until the desired temperature (up to 800°C) is reached. The heating medium will then flow out of the outlet nozzle at a fixed flow rate determined by the temperature control mechanism. Tools such as the RTDs and digital thermocouples can be used to precisely control the temperature of the heating system. For extra protection, optional components such as moisture resistant or explosion-proof housing are available for special applications. Drain valves are also available on the circulation heater to facilitate the procedure with the system maintenance, whereas the leftover fluid or residues (such as water or Calcium) can be easily removed from the equipment. Special mounting options are available for the target application’s mobility requirement. The flange immersion heater inside the circulation unit can be customized by SAW HEAT®’s manufacturing depending on the chemical and physical properties of the target fluid. Other customization options, such as the equipment orientation (vertical or horizontal) or flange type, are also available to consider for your target application.Inline heaters comprise of heating elements that are mounted in a rounded tube. Often, the flanged heater is thermally insulated by either the side or inline operation so that the efficiency of the heating process can be increased. This is particularly done when a flowing medium has to be heated. Almost all inline heaters use thermocouple sensors that can be integrated with any control to manage the temperature range. Different applications call for varying options for the terminal enclosure, sheath material, flanged connections, and temperature ranges. Several mounting options are also available such as integral mounting utilizing SCRs and remote mounting which uses contactor control panels. A vessel heater is manufactured as a packaged unit which contains several components such as heating element, chamber, thermostat, sensors, insulated material, brackets for mounting andelectrical connections. The efficiency of this heater is high as all heat is produced within the substance or vessel. The operation is fast and executed in a short time. The heat generated is evenly distributed throughout the substance. Many applications make use of industrial heaters. The most common of these are heating oils, corrosive solutions, water cooled engines, oil sump heaters, process kettles, blending mills, molding dies, steam superheating and preheating purposes such as viscosity pumping and oil delivery to burners.
Hopper Heater
Thermocouple Sensor
Thermocouples A thermocouple is a sensor for measuring temperature. It consists of two dissimilar metals, joined together at one end. When the junction of the two metals is heated or cooled a voltage is produced that can interpreted by a temperature controller, high limit or display device. There are two common constructions for these: Tube and Wire and Mineral Insulated. The tube and wire uses an empty stainless tube with a wire inside which has a welded tip incorporating the wire junction. This construction is typically used to 900?C. The Mineral Insulated construction uses a highly compacted stainless sheath with solid conductors encased in magnesium oxide insulation. This construction offers a wider variety of diameters, allows for the sensors to be bent in the field and for temperatures to 2200?C. These sensors are available is a huge range of physical packages with a variety of lead wire, housing, and mounting options. RTD's Resistance Temperature Detectors (RTDs) are temperature sensors that contain a resistor that changes resistance value as its temperature changes. RTDs are also available in a Tube and Wire and Mineral Insulated construction. They are more accurate than thermocouples and are typically used for temperature sensitive and laboratory applications. We offer these in a variety of constructions and physical packages but are constrained by the size of the resistor beads. There are restrictions to the diameter and lengths of the available constructions
