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

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.

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

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

9. NIR can heat through materials via Radiation and not only convection
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

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

11. NIR Technology Comparison

12. NIR Technology Advantages
Ultra short energy emission spectrum (up to 90 % below 2 µm)
Extreme high energy density (up to 1 MW/m²)
Volume heating
Defined heating profile (high efficient, high focusing reflectors)
Defined and precise energy/heating control
Production approved technology
Low maintenance
