Heraeus offers the patented "Golden 8" lamp design as well as a QRC Nano for special applications.

"Golden 8" Lamp Design

golden8 The presence of the Golden 8 quartz twin tube is a reliable sign of competence, expertise and quality in infrared heating. The starting point for effective solutions in heating processes, the patented Golden 8 quartz twin tube is the basis of all Heraeus Noblelight twin tube infrared heaters. Heraeus Golden 8 infrared heaters (infrared lamps) are made with high-quality quartz tubes and gold reflectors for the highest efficiency.

The unique Heraeus Twin Tube design (the Golden 8) provides high radiation power and very good mechanical stability to your heating application. Twin-tube heaters are available from Heraeus in custom and standard cofigurations in lengths up to 6.5m. Heraeus Golden 8 infrared heaters are available in short wave, medium wave, or fast response medium wave versions. This wide array allows you the possibility to select the optimal wavelength for the material to be heated. Dimensions and filaments of the infrared heaters are matched to your specific requirements.

golden8_features The unique gold reflector is a critical feature of the Golden 8 infrared heaters. It allows direct, targeted heating of the product. The gold coating on the infrared heater reflects the infrared radiation. Consequently the infrared radiation impinging on the product is virtually doubled.

Heraeus infrared heaters are also available in a nearly endless array of special designs, e.g. as omega-shaped or bent heaters, or as complete infrared systems.
