Heraeus Golden 8 infrared emitters are made of high-quality quartz tubes and feature a gold reflector for highest efficiency. Heraeus's unique twin-tube layout (the "Golden 8") gives the emitters a higher radiation density and improved mechanical stability. They are available as short-wave, medium-wave and fast medium-wave infrared emitters. This allows you to choose the optimal wavelength for the material to be heated. Dimensions and filaments are fabricated to meet your requirements.

Good to know
Gold reflector
Heraeus Noblelight manufactures infrared emitters with a gold reflector that allows directed emission of heat to the product. A gold coating on the infrared emitters reflects the IR radiation. This almost doubles the efficient radiation onto the product.
Twin tube
The unique twin-tube design features high radiation capacity and very good mechanical stability, even on emitters which are 6.5 metres long. Wavelengths, dimensions and filaments are fabricated to meet your requirements.
Quartz glass
Heraeus Golden 8 infrared emitters are made of high-quality quartz tubes. Quartz glass is very pure and features good transmission and thermal stability.
Golden 8
A sure sign of competence and quality in infrared heat technology: the Golden 8! The eight-shaped emitter cross-section, the twin tube, the gold reflector: the Golden 8 stands for all our twin-tube emitters and is the starting point for constantly new heat process solutions.
