Heating

Heating requirements are critical in many different processes in the manufacturing industry, to fulfil such requirements heating elements are used heavily because they can be shaped and customised to different size, specification, configuration. The option to change different materials allows for most applications across different industries. But the fundamentals remain the same, these heaters convert electrical energy to heating energy and the heat is disbursed through contact with air, liquid, and solids.

Since the heaters allow for flexibility, many will find them being used in infrared heaters, flexible heaters, quartz heater’s just to name a few. All these heaters can be found in industrial or commercial application whether to control or maintain a certain temperature. The most widely used heating element today, also one of dpstar’s mainly supplied and distributed heater in Malaysia is tubular heaters, they can be found on kitchen stovetops and dishwashers. While other heating elements can be seen in industrial and commercial application in kilns, tanks, and drying ovens.

dpstar’sheating elements is produced under our trademark Maltec-H brand, we are one ofthe largest makers and suppliers of such heaters in Malaysia and South-eastAsia. 

RTD – Resistance Temperature Detector

An RTD ( resistance temperature detector) is a temperature sensor that operates on the measurement principle that a material’s electrical resistance changes with temperature. The relationship between an RTD’s resistance and the surrounding temperature is highly predictable, allowing for accurate and consistent temperature measurement. By supplying an RTD with a constant current and measuring the resulting voltage drop across the resistor, the RTD’s resistance can be calculated, and the temperature can be determined.

Different materials used in the construction of RTDs offer a different relationship between resistance and temperature. Temperature sensitive materials used in the construction of RTDs include platinum, nickel, and copper; platinum being the most commonly used. Important characteristics of an RTD include the temperature coefficient of resistance (TCR), the nominal resistance at 0 degrees Celsius, and the tolerance classes. The TCR determines the relationship between the resistance and the temperature. There are no limits to the TCR that is achievable, but the most common industry standard is the platinum 3850 ppm/K. This means that the resistance of the sensor will increase 0.385 ohms per one degree Celsius increase in temperature. The nominal resistance of the sensor is the resistance that the sensor will have at 0 degrees Celsius. Although almost any value can be achieved for nominal resistance, the most common is the platinum 100 ohm (Pt100). Finally, the tolerance class determines the accuracy of the sensor, usually specified at the nominal point of 0 degrees Celsius. There are different industry standards that have been set for accuracy including the ASTM and the European DIN. Using the values of TCR, nominal resistance, and tolerance, the functional characteristics of the sensor are defined.

dpstar manufactures Maltec-RTDs for many industrial applications. From single- or dual-element RTDs to Pt100’s we have the right sensor They have been used for many years to measure temperature in laboratory and industrial processes, and have developed a reputation for accuracy, repeatability, and stability.

Open Coil Element

Open coil elements are the most efficient type of electric heating element while also the most economically feasible for most heating applications. Used predominantly in the duct heating industry, open coil elements have open circuits that heat air directly from the suspended resistive coils. These industrial heating elements have fast heat up times that improve efficiency and have been designed for low maintenance and easily, inexpensive replacement parts.

Open coil heating elements from dpstar  are typically made for duct process heating, forced air & ovens and for pipe heating applications. Open coil heaters are used in tank and pipe heating and/or metal tubing. A gap is required between the ceramic and the inside wall of the tube. Installing an open coil element will provide excellent and uniform heat distribution over a large surface area. 

Open coil heater elements are an indirect industrial heating solution to decrease watt density requirements or the heat fluxes on the surface area of the pipe connected to the heated section and prevent heat sensitive materials from breaking down.
 

dpstar also manufactures other Industrial heating products such as Infrared heaters, control panels, Circulation heaters and more.

Infrared Heater

Ceramic infrared heat elements are efficient, robust heaters which provide long wave infrared radiation. The ceramic heaters and infrared heaters are used in a diverse range of industrial and engineering applications such as thermoforming heaters, packaging and as heaters for paint curing, printing and drying. They are also used very effectively in infrared outdoor heaters and infrared saunas. Ceramic elements produced by Ceramic include ceramic trough elements, ceramic hollow elements, ceramic flat elements, and ceramic infrared bulbs.

Ceramic elements operate in the temperature of 300°C to 700°C (572°F – 1292°F) producing infrared wavelengths in the 2 – 10 micron range. Most plastics and many other materials absorb infrared best in this range, which makes the ceramic heater the most popular infrared radiant emitter on the market. A range of aluminized steel reflectors are also available to ensure the maximum amount of infrared radiation is reflected forward to the target area.

Heating element

Heating elements are used to produce high temperature in electric heaters. Electric heating elements can be seen or found in electric heating machinery and can come in all shapes and sizes. Heating Elements by dpstar Manufacturing (Malaysia) brand Maltec - H are produced and customised in with different specifications and material for different application, but their overall function remains the same: to convert electrical energy into heat energy, then to transfer that heat energy to or through air, liquid or solids by convection, conduction or radiation.

There is a wide range of industrial heating elements that can be used to fulfil all kinds of machinery, systems, and applications. dpstar Group is a top and renowned heater supplier and distributor in Malaysia, the types of these heaters are infrared heating elements, immersion heater elements, flexible heating elements, quartz heating elements and many more just to name a few. Many of such heating element varieties can be found in general household appliances in daily life. For example, tubular heating elements, one of the most general types of heaters which can be bent or made in different shapes, are used in consumer ovens and in dishwashers. Heating coils can be tubular, such as stovetop elements, or they may be wire, such as those that are used in toasters. Wire heating elements are almost certain to be found in commercial dryer heating elements; kilns, surface treatment heaters and many other kinds of dryers make use of wire elements. Ceramic heating elements, many of which are SiC heating elements, are used for convectional heating, such as in space heaters, furnaces and semiconductors. Heater elements have the capacity to produce temperatures as high as 1300° F.
