Ceramic heating elements

The currently smallest heating element can be seen in the picture above with dimensions of just 7x3x1.5 mm and a maximum temperature of 500°C.

Despite its small dimensions, the HS flat heater is extremely powerful with a nominal output of over 30 W. The small flat heating elements are primarily used where heat needs to be generated precisely and with high power density in a small installation space, for example in nozzle heating systems, for dynamic heating of tool tips – for example in pick-and-place applications, flip-chip or die-bond processes in electronics and semiconductor production.

Due to the low mass of the heating element, there is no need to heat a lot of surrounding Material unnecessarily: This helps to save energy by preventing waste heat from escaping into the surroundings of the heating element. The “thermal mass” remains low, the heating element reacts dynamically when heating up and also cools down again quickly.

With a nominal output of over 40 W, the Type HR heating element is a powerful miniature heater. The square design of the width and height of the heating element means that the side surfaces can also be used for heat transfer. This makes the Type HR ideal for partially recessed mounting, for example for space-saving and targeted heating of high-power machine parts, such as in plastic injection molding machines or packaging machines.

With its practical square base area of 12 x 12 mm, the Type HT heating element is often used as a heated sample carrier in research and development applications. The good chemical resistance of the heating element’s silicon nitride ceramic allows such Usage even with aggressive sample material. The hardness and wear resistance guarantee Lengthy usability. Other areas of application include microelectronics and medical technology.

Type CLB heating elements can be used to achieve maximum surface performance and heating rates. The version according to item no. BA FLE 100303 has a nominal power of over 230 W – with a base area of only 14 mm x 14 mm! With this power, the heating element can heat up at over 150 K/s. Particularly important here is to use suitable control technology whose control speed can keep up with the heating element.

Due to the contacts arranged close to each other on the sides, the electrical contacting of the Type HJ heating element can be realized in a very space-saving manner. This makes the heating element particularly suitable for mounting in cavities with contact on both sides of the material to be heated, for example in metal tools such as deep-drawing and injection molding tools.

With a maximum temperature of 1,000°C and a heated zone of 35 mm x 25 mm, Type RDB is a very universal heating element: it can be used both as a contact heating element and for radiant heating. This type of heating element is also available in many different configurations for different operating voltages and outputs as well as with and without a hole for an optional Temperature probes. Type RDB is used, for example, as a heating element for heating samples in research & development applications, as a radiant heater for welding plastics and as a high-temperature heater for coating applications.

The maximum temperature of 1,000°C and the favorable dimensions of the heated zone of 50 x 50 mm allow the Type HV heating element to be used for a wide variety of applications. For example, by using several Type HV heating elements with a suitably arranged “cold zone”, cuboid or cube-shaped bodies can be heated up to 1,000°C.

Type IP (IPR/IPL) glow igniters make it possible to achieve (ignition) temperatures of up to 1,000°C with a very compact heating element with 24 V nominal voltage. The two available versions IPR and IPL differ in the orientation of the electrical contacts.

However, the small glow igniters can not only be used as igniters – for example for wood pellets – but can also be used for contact heating of various substrates and for igniting process gases.

Type IPB glow igniters make it possible to achieve (ignition) temperatures of up to 1,000°C with a very compact heating element. The two available versions differ in the orientation of the electrical contacts. However, the small glow igniters can not only be used as igniters – for example for wood pellets – but can also be used for contact heating of various substrates and for the ignition of process gases.

Glow igniters measuring 75 x 14.7 x 4.4 mm are available in a variety of different performance classes. With free convection and radiation to air at room temperature, these heating elements are designed to reach their target temperature when operating at nominal voltage without additional control technology. The robust design of these heating elements in conjunction with the good oxidation resistance of the silicon nitride ceramic ensures a long service life – both in continuous operation and under cyclical stress. Glow igniters are mainly used to ignite wood pellets in heating systems.
