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.

Over-the-side Immersion heaters

dpstar Group is aleading manufacturer and supplier in Malaysia of liquid immersion heaters usedin tanks, vessels, or any other application where increasing the temperature ofthe said medium is required. Over-the-side immersion heaters are made for tanksand vessels due to the issues of installation of traditional immersion heaters.These heaters are typically made to certain customer specification and ismounted on the top or at the bottom of such tanks/vessels. Options for materialof such heating elements are in copper, steel, stainless steel, cast iron,Indology, titanium, and PFA coated. Dpstar manufacturing is a top customizeddistributor of heaters where they can be made to order, to all kinds ofspecifications, design to suit customer’s application. The large variation in heating elementmaterial and shapes of over-the-side immersion heaters offer a wide selectionso that the exact requirements of the application can be fulfilled whether itis water, oils, solvent, plating baths, salts and acid or any othervicious/corrosive liquids. Such over-the-side heaters offer flexibility andconvenience for installers as well as easy removal for cleaning of tanks andheaters, and also helps save space where needed.

Heating elements

Heating elements can be found as a core fundamental material within electric heaters and are typically consisted of an insulating core, a heat conductive coil wrapped around the insulation and a protected sheath made from stainless steel, aluminum, nickel or iron. Heating elements can have a short lifespan if the application is incorrect, hence the need and importance that a person/company using such heaters are consulted professionally so that the right material is used. Through dpstar’s Maltec - H (Malaysia) manufacturedheating elements, our experience of nearly 30 years in the field allows us to give expert advice on the right heater for every application. Replacement of such heaters within a short time period can be very expensive and be a waste of a company’s expenditure. Most industrial companies that use such heaters acknowledge our heaters because they no longer need to replace heating elements part of regular equipment maintenance so frequently. Hence maintenance department can keep less of these parts and lower their inventory. When heating elements are used wrongly in consumer items such as hair dryers or toasters, it is typically easier and less expensive buy a whole new unit than replace a single element. dpstar’s manufacturing division goes through strict quality control processes and we manufacturers industrial heaters of high quality and customers are able to save on spare part maintenance. Using the right heating element material for every application is very critical and important, as the safety and effective operation of a heating element depends on it. Using wrong heating elements can potentially cause danger and risks such as fires, burning, product damage, equipment breakdown and many other problems.

dpstar’s Maltec H heating elements is able to offer our wealth of experience for heater applications so that such extra costs and problems do not occur to our customers.

Thermocouple 

dpstar is the largest in OEM manufacturing and customization of  Heating Elements and Thermocouples in Malaysia. We supply direct to end-users and machine makers throughout Malaysia and the Asian region and also through our appointed distributors. We are the only  Thermocouples and Heating Elements supplier in Malaysia to be accredited with UL and CE certification and our trademark brand is  Maltec-T (Thermocouples) and Maltec-H (Haltering Elements) respectively.

Thermocouples consist of two wire legs made from different metals and it function as a sensor to measure temperature. The wires legs are welded together at one end, creating a junction and when the junction experiences a change in temperature a voltage is created. The voltage then can be interpreted to calculate the temperature.

Thermocouples come in various types, each with its own characteristics in terms of temperature range, vibration & chemical resistance, durability, compatibility etc..

The most common types are type J, K, T, & E.  For high temperature application type R, S, and B thermocouples are most commonly used.

Thermocouples are used in many industrial, scientific, and OEM applications. They can be found in nearly all industrial markets: Rubber/Glove, Power Generation, Oil/Gas, Pharmaceutical, F&B, Steel, Cement, Paper/Pulp industries etc.

Our experience of 30 years in this field allow us to give expert advice on the specific thermocouple for every application.
