DHE, a leading Industrial coil heater manufacturer in India, Offer a coil heater has a high degree of adaptability and can be adapted to a variety of applications, such as a machine nozzle or ducting, through the spiralization of straight electric heating profiles and pipes. Coil heaters provide a high thermal performance within the coil section, and are available in a range of wattages and surface loads. They are capable of providing high performance in small areas up to a temperature of 750°C, and can be designed with or without integrated temperature control units. For precise operation of each individual coil heater, we can optionally include thermocouple type “J” and “K”.
DHE offers Electric Coil Heaters that can be classified based on their levels of energy input and heat output. Furthermore, they can be categorized according to the shape of the heating coil and whether the design is open or closed.
Open-coil heaters have the metal coil directly exposed. Because of this, heat has no covering to protect it. As a result, there is excellent efficiency in the heat energy transfer from the coil to the surrounding medium. These designs are considerably less expensive and require less upkeep than other options. The Coil, however, can be vulnerable to damage and might not be suitable for all heating applications, particularly when safety is an area of concern. They act as a de facto way to reduce the amount of watt density needed and stop heat-sensitive materials from degrading.
DHE offers Silicon carbide has a high electrical conductivity compared to other ceramic materials. The elements are formed by pressing or extrusion followed by sintering. Rods and tubes are the most common types of heating elements. They have a diameter of 0.5 to 3 inches and a length of between 0.2 and 3.5 meters. They have metallic ends for electrical connections and often have both connections on one end. They often have two helical slots that stop short of each other, similar to a twisted hairpin shape.
DHE offers Metallic heaters have the metal heating element directly exposed. Because of this, heat has no covering to protect it. As a result, there is excellent efficiency in the heat energy transfer from the Metallic heating element to the solutions. These designs are considerably less expensive and require less upkeep than other options. They act as a de facto way to reduce the amount of watt density needed and stop heat-sensitive materials from degrading.
DHE offers Ceramic Bobbin heaters are a unique kind of steatite heating element that can be used to both directly heat air and indirectly heat liquids, air, and gases that have been inserted into radiation tubes. These tubes are inserted into the medium, and the tube is then fitted with a bobbin heater. In order to create the desired length of bobbin heaters, ceramic segments are assembled. Users can fit open heating coils in the recessed areas of the segments. Through this design, the heating coils will maintain good electrical insulation and be shielded from contact with the chassis.
Now it is simple to replace the ceramic heater without draining or opening the tank. The tubes come with a flange or thread for simple attachment as well as sensors, thermostats, or limiters that are integrated into specialized connection boxes.
DHE offers the Bundle Rod Heater, which features a slotted circular ceramic disc that holds the multiple rod heater elements. Bundle Rod Heaters are used with radiant tubes; they produce a higher power output, avoid refractory corrosion, and prevent gaseous impurities in processed materials. These heaters are designed for long-term and maintenance-free use. Elements can be made from ferritic alloys up to 1250 °C and from NiCr alloys up to 1100 °C.
A radiant heater is suitable for Industrial ovens and furnaces for aging, annealing, brazing, hardening, heat treating, holding, melting, muffle, pitting, powder coating, or sintering.
We at DHE Heaters Pvt. Ltd. produce the top of the line temperature sensing devices also known as 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 480ºC. 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 1200ºC. These sensors are available is a huge range of physical packages with a variety of lead wire, housing, and mounting options.
