Infrared radiation is a reliable heat source for many industrial heating processes. Infrared heating technology transfers large amounts of energy in a short time. It helps save energy because it can be easily switched on and off. Heraeus infrared heating technology offers important features: Heating only where it is required, with the optimal wavelength for the product to be heated and in harmony with the process.
Operating in Vacuum
Infrared heating technology requires no contact with the material and no intermediate medium such as air or water. Heraeus can modify its infrared heaters to operate under vacuum conditions. These can be produced with individual sockets, leads and voltages. Every closed heater type can be modified for the operation in vacuum: Short wave, fast response medium wave, or carbon. And Noblelight offers special seals for ultra-high temperature situations in vacuum environments.
Features and Advantages
Tungsten or carbon
Fire polished for clean room conditions
Single- or double-ended lamps
Molybdenum wire connections
Heraeus can construct complete IR systems to operate in vacuum. For any special application we can modify the standard lamps.
Infrared Applications Include:
Heating wafers in de-gassing and annealing processes
Drying of products in vacuum chambers
Heating of float glass prior to coating
Coating processes in vacuum chambers
CVD (Chemical Vapor Deposition) - application of anti-reflection layers
CIS and CIGS - manufacturing processes for thin film solar cells
