QRC® INFRARED HARAEUS HEATER WITH NANO REFLECTOR
The benefits of infrared heat can also be realised under extreme process conditions. Thanks to a newly developed quartz reflector, heating processes can be carried out significantly better in vacuum or at high surrounding temperatures.
QRC® (quartz reflective coating)
Unlike conventional reflectors, the new nano reflector is not made of gold or metal oxides but of opaque quartz glass. Quartz glass is extremely heat-resistant, as well as being resistant to attacks from acids, lyes and other aggressive substances.A gold coating on the infrared emitters reflects the radiation very effectively, to the extent that the effective radiation onto the product is almost doubled. Measurements have shown that the opaque quartz material has a reflectivity of around 60 to 70%. This is less than gold but similar to that of a highly polished aluminium reflector. However, an aluminium reflector progressively loses its reflectivity, as, over time, aluminium oxide builds up on its surface. In contrast, Quartz glass forms no such oxide coating over time.
The new reflector sits directly on the emitter and, unlike an external reflector, there is no additional fitting necessary to fix it in position.
Bent QRC heaters for edges and contours
We continue to develop the QRC infrared heater. New are QRC heaters which are bent or formed to fit exactly to edges or contours of a product. This helps to target heat e.g. for deburring or welding of three dimensional plastics products.
