A reliable sign of competence and quality in infrared heating: the Golden 8 quartz twin tube is the basis of all our twin tube infrared heaters and is the starting point for new solutions in heating processes. Heraeus Golden 8 infrared heaters (infrared lamps) are made with high-quality quartz tubes and gold reflectors for high efficiency. The unique Heraeus Twin Tube design (the Golden 8) offers high radiation power and very good mechanical stability – allowing heaters of lengths up to 6.5 metres. Heraeus Golden 8 infrared heaters are available in short wave, medium wave, or fast response medium wave versions. That gives you the possibility to select the optimum wavelength for the material to be heated. Dimensions and filaments of the infrared heaters are matched to requirements. The gold reflector is another unique feature of the Golden 8 infrared heaters. It allows to emit heat directly to the product. A 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 special geometries, e.g. as omega-shaped or bent heaters, or as complete infrared systems.
