The Most Powerful Carbon Infrared Emitter in the World

08.12.2009
  • CIR® carbon infrared emitters heat plastics, glass or water with particularly high efficiency
  • Heraeus Noblelight now produces carbon infrared emitters in a new power class

For decades infrared emitters have been successfully used in industrial heating processes to dry coatings, form plastics and to manufacture solar cells. Since the 1990s, carbon infrared emitters have helped to save up to 30% in energy consumption in many processes.

In October, the manufacture of the world’s most powerful carbon infrared emitter was brought on stream at Heraeus Noblelight in Kleinostheim, Germany. Carbon emitters can now be manufactured in lengths up to 5 metres.

To date, the most powerful carbon emitters measure 2.5 metres long with a nominal power of around 14kW, which is twice the power output which could previously be achieved by carbon emitters of such lengths. New long, high power carbon emitters operating at the effective medium wavelength, with a very fast response time will give a homogenous and even heating in one length.

The wavelength of infrared radiation has a significant influence on the process. Shortwave radiation penetrates deeply into large components and heats these rapidly and evenly. Medium wave radiation is effectively intensified at surfaces and is also very easily absorbed by water, glass and many plastics so that it is readily directly converted into heat.

Changing over to medium wave carbon infrared emitters can help to provide significant savings in energy costs. Comprehensive tests demonstrate that carbon emitters require up to 30% less energy than conventional shortwave emitters in the drying of water-based paints and lacquers. The CIR® carbon emitter has been matchless on the market for years as it combines medium wavelength radiation at high power with very fast reaction times in heating coatings, glass and plastics.

When drawing, laminating, embossing or stamping foils, infrared emitters which cover the total web width are of great advantage. Carbon infrared emitters heat the surface of plastic materials exactly at the surface, for example directly in front of the embossing slot, and homogenously over the web width.

Very long carbon emitters are also advantageous in the heating of coatings on tracks, strips and rollers.

Long Carbon Emitters Increase Safety
Conventional medium wave infrared emitters offer powers up to 60kW/m² with reaction times of the order of 2-3 minutes. In the event of an unanticipated stoppage of the conveyor belt, conventional medium wave emitters need to be swivelled away or screened, both actions taking some time, in order to prevent damage to the web. Carbon emitters have power ratings up to 150 kW/m², they have reaction times of the order of seconds and can be almost immediately switched off in the event of belt stoppage.
Heraeus Noblelight offers the complete palette of infrared from NIR near infrared to CIR medium wave carbon infrared, carries out trials with materials to be heated and advises on the selection of the optimum emitter for specific processes.

Heraeus has more than 40 years experience of infrared emitters, both for end-users and for large OEMs. It carries out practical tests and trials using customers’ own materials in its in-house Application Centres, to establish the best process solutions.

Heraeus Noblelight GmbH with its headquarters in Hanau and with subsidiaries in the USA, Great Britain, France, China, Australia and Puerto Rico, is one of the technology and market leaders in the production of speciality light sources.

Im Focus: Manipulating Electron Spins Without Loss of Information

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.

For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...

Im Focus: The proton precisely weighted

What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.

To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
