Today I made some basic studies about the quartz heating element that is used for our oven. The quartz electric heating elements provide medium-wave infrared energy with a fast heat up and cool down time. With element temperatures ranging from 1000 °F (537°C) up to 2000°F (1093°C) the elements produce infrared energy in the 2 to 3.5 micron range. Lower operating temperatures produce longer wave lengths. Quartz Infrared offers both clear and satin (translucent) quartz. Clear quartz radiates about 95% of the infrared energy directly, whereas satin quartz absorbs about 35% of the energy and radiates it at a longer wavelength.
Some of the quartz important specifications are listed below:
Product Tolerances:
Electrical tolerances:
- Resistance/Wattage: +/- 5 percent
