Many industrial processes experience product quality issues due to non-homogeneous radiant heating. Whether the process is baking of bread to curing of composite materials, or the drying of slurry mixtures, use of non-contact radiant heating is a common heating method. Unfortunately, the lack of thermal uniformity leads to unevenness in heating and a loss in efficiency and poor product quality.
ESI has experience in the testing of non-contact radiant heating fixtures using various high intensity lamps and taking into account the surrounding environment. Figure A is a typical heater containing multiple high intensity halogen lamps, used for material heating studies. The ESI team verified a less than uniform thermal source (Figure B).
