The source temperature for short-wave infrared emitters is up to 4,000oF (2,204oC). It has a peak wavelength of 1.2 micron with a response time of less than one second. According to a fact sheet from ITW BGK Finishing Systems, Minneapolis, there are multiple advantages to using short-wave infrared in industrial processes. They include:
- Immediate heat source response.
- Zero to 100 percent control of energy output.
- High thermal differential between source and product for rapid heating and short process times.
- Independent heat zones for process flexibility and energy savings.
- Ramp-and-hold capability.
- Efficient use of applied energy.
- Flexible system configurations.
- Compact designs for small spaces.
- No preheating needed.
- Minimal supply air required.
- Minimal internal moving air for optimal product finish.
- Minimal exhaust air required.
- Consistent product quality.
- Clean energy source with low environmental impact.
Many industrial processes are inline, where it is critical that the heat source rapidly adjust for changes in product speed, mass and shape. Short-wave infrared technology offers this capability, according to ITW BGK.
