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.
DHE offers U-shaped multi-finger tubular heaters as well as custom-bend tubular heaters. The double-ended heating element can be shaped into a variety of shapes, such as spiral, compound, multi-axial, and multi-plane, from standard bend configurations. Furthermore, custom-bonded heating elements with tighter tolerances are available to meet the requirements of particular applications. Multi-shape heating elements offer a wide range of mounting and termination configurations, making them highly sought-after by industrial customers.
DHE offers Finned Tubular heaters that are fitted with fins are more efficient than those without. This is due to the fact that the fins increase the surface area, allow for a quicker heat transfer to the air, and allow for increased power output in confined areas. They're made up of tubular heaters and have electro galvanized steel fins. They can be designed in a wide range of electrical ratings, diameters, lengths, terminations, and sheath materials. Tubular heating elements are capable of conveying heat through all three of these modes: Conduction, Convection and Radiation. Tubular heating elements are available in single-ended and double-ended configurations
DHE Heaters, one of the leading Tubular Heater Manufacturers in India and a trusted name among Tubular Heater Manufacturers in Ahmedabad, offers high-performance tubular heaters known for their adaptability, durability, and reliability. These heaters are expertly engineered to meet a wide range of industrial heating requirements and can be factory-customized in terms of electrical ratings, diameters, lengths, terminations, and sheath materials.
The core design features a resistive wire or coil enclosed within a precisely centered metal sheath, surrounded by high-grade magnesium oxide. This construction ensures efficient heat transfer from the coil to the medium. Tubular heating elements effectively operate through conduction, convection, and radiation, offering excellent thermal performance in various applications.
Available in both single-ended and double-ended configurations, tubular heaters can suit diverse installation needs. Single-ended designs have both terminals on one end and come with flexible lead wires crimped to terminal pins, protected by silicone-enriched fiberglass sleeves. The double-ended version is highly flexible, ideal for custom bending during field installations.
With long-lasting construction and versatile functionality, DHE's tubular heaters are a reliable solution for demanding industrial environments across India.
DHE offers Tubular heaters are renowned for their adaptability, durability and reliability. They can be virtually factory-fitted to meet a wide range of industrial heating requirements. The fundamental principle of the design is to enclose a resistive wire or coil in a precisely centered metal sheath, surrounded by magnesium oxide, in order to facilitate the efficient transfer of heat from the coil to the heating medium. They can be designed in a wide range of electrical ratings, diameters, lengths, terminations, and sheath materials. Tubular heating elements are capable of conveying heat through all three of these modes: Conduction, Convection and Radiation. Tubular heating elements are available in single-ended and double-ended configurations. Tubular Heaters with a single-ended design have both terminals located at one end of the heater. The other end is sealed. Lead wires that are flexible and are crimped to the terminal pin are equipped with sleeves made of silicone-enriched fiberglass. The double-ended is highly flexible in terms of bending, particularly when bending in the field. Both single-and double-ended structures have a lot of built-in features that help them last a long time.
DHE offers manifold Tubular heaters are the most advanced technology solutions for injection-manifold heating needs. These heaters are mainly used for hot-runner molding systems and hot plates. The square part of the heating component facilitates optimal heat exchange and facilitates its installation with ease. A perfect fit helps transfer heat to the work surface. With our experienced benders and special bending tools, we can bend intricate shapes. Manifold heaters come in a variety of sizes, including 6mm, 7mm, and 8.5mm diameter heaters with threaded studs and lead wire termination.
