ffInfrared Emitters –
for every application
Every Heraeus emitter can be adjusted to the appropriate shape, length and spectrum for the required process. This makes even complicated heat processing reproducible and enables an automation of the process.
Selection criteria for infrared emitters
Infrared spectra define the heat distribution in plastics.
By matching the infrared spectrum to a specific application, the process flow rate, heating time and energy used are optimised.
The emitter’s rates of heating and cooling are important
for control, cycling process stages and process safety. Short wave emitters, fast response medium wave emitters and car- bon emitters have the quickest response times and therefore the most favorable control characteristics.
Length and physical strength – Halogen emitters are manufactured with a heated length of up to 1 m and carbon emitters with a heated length of up to 3 m. Because of their high physical strength, twin tube infrared emitters can be supplied in any length required up to 6 m.
Reflector – On request Heraeus Noblelight offers emitters with gold reflectors. With a gold coating approximately 95 % of the IR-radiation can be absorbed, which doubles the ef- fective intensity.
