Technology and its advantages • igh surface power up to 150W/cm2 and h radiation emission e > 0.8 Our 100% ceramic heating elements are made of silicon nitride or aluminum nitride with an integrated ceramic heating conductor. Due to its low density, the ceramic material has a number of advantages over against conventional metallic heating elements. Temperatures up to 1,000°C can be handled with low energy consumption. This extraordinary technology enables manufacturing of high-performance ceramic heating elements in various shapes and sizes. Silicon nitride and aluminum nitride ceramics are...

Flat heating elements made of high-performance ceramics Our flat heating elements made of silicon nitride ceramics can be operated in air up to 500°C and optionally up to 1,000°C. The adjustment of the heater to the respective application is achieved through compensation of heat loss or integration of several zones for separate temperature control. Temperature sensors can easily be integrated for exact temperature measurement in the required exact location. Our flat heating elements are available in different standard sizes as well as in custom-made designs. The design of the heaters can be...

< kW hotplate for the operation in air up to 1,000°C with a sectional 2 view of the design of the heating conductor Hot plates for industrial applications Our hot plates are usually rectangular or round but can be adjusted to the dimensional requirements of your system. Features such as holes and slots for rotational alignment and shallow holes for thermosensors can be integrated. Using 3D design and FEA, the ceramic heating conductor can be designed exactly to the heat dissipation requirements of the application. Multi-zone heaters can be manufactured to achieve superior temperature...

< Ring-shaped tool heater with 1kW power at 40mm outer diameter Heating rings made of high-performance ceramics Our heating rings can be operated at temperatures up to 500°C and optionally up to 1,000°C. Various standard sizes are available as well as custom-made designs. Features such as holes, slots, grooves, and edge cutouts can be machined for fixation in the machine and for integration of thermosensors. The surface can be machined to flatness values down to < 1μm. Your advantages • Reduction of cycle times of your machines and processes. • Elimination of preheating time or reduction of...

Heating elements for packaging machines Heated comb for welding of foils > Our ceramic heating elements made of silicon nitride are available in various shapes and sizes, thus allowing the exact adjustment of the heating element to the dimensions of the goods to be packed. In general, our heaters are ring-shaped, rectangular or designed as heated rails. However, more specific shapes – such as ground cutting edges with directly heated blades or comb and cone structures – can be produced. Ramping curve of a heating element for packaging machines (45 x 25mm) 500 T in °C The good thermal...

Chip heaters – miniature heaters made of silicon nitride We provide miniature heating elements with a surface power of up to 150W/cm2 and heated areas as small as 1mm2. These heaters can be operated at up to 1,000°C in air and are characterized by very fast heating and short cycle times. In contrast to metals, the low dilation of the ceramic material allows the heater surface to remain exceptionally flat even with fastchanging temperature. Due to the mechanical strength of hot-pressed silicon nitride it withstands high load and shows excellent wear resistance. The inert and chemically...

Wafer heaters made of silicon nitride ceramics Our large-sized hot plates achieve very high temperature uniformity, their individually controlled multi-zone heating conductors compensating for heat loss. Even temperature profiles can be individually adjusted. Highest accuracy in surface treatment and low thermal expansion of the ceramic materials in use ensure steady heat transfer up to high temperatures. The cooling process can be accelerated by brazing a second ceramic plate with cooling channels onto the heater in a sandwich construction. Flanges for cooling media can be integrated, the...
