3 NIR - Technology

4 NIR Technology Definition of NIR NIR = Near Infra Read 4

5 NIR Technology General It started with space technology Starting point were attempts of simulating the heat shock of orbital gliders during re-entry into the terrestrial atmosphere. The NIR -Technology (NIR: NearInfraRed) enables an application of the highest energy on different substrates. 5

6 NIR Technology Absorption Example Transparent PET Transmission [%] NIR Emitter (3500K) IR Emitter (2500K) Wavelength [µm] 6

7 NIR Technology Comparison of Technology NIR Technology mode of action Near Infra Read Induction Infra Read Hot Air 7

8 NIR Technology 1 MW/m² Heating up a 2,5 mm thick steal plate in 30 sec from ambient to 900 C. NIR can apply an energy density of 1 MW/m² on a homogeneous field NIR can apply an energy density of 4 MW/m² on a line 8

9 NIR Technology Volume heating NIR can heat through materials via Radiation and not only convection NIR reduces process times by Factors NIR reduces blistering during drying processes Heating up 4mm thick plastic in 6 sec to 120 C with a temp difference of>10 C 9

10 NIR Technology Fast reacting systems NIR requires 0,5 2 sec from 0 100% NIR can be regulated to achieve ± 1K 10
