Ceramic infrared heater product introduction
Ceramic infrared heaters consist of resistive thermal conductors completely embedded in suitable ceramic materials. Because it is completely embedded in the ceramic, the energy generated by the thermal conductor can be transferred to the surrounding materials, which not only prevents the thermal conductor from overheating, but also prolongs its service life. The material used to embed the thermal conductor must be insulated and have good absorption and radioactivity within the set infrared radiation range. To meet this requirement, ceramic infrared heaters can be made into different geometric shapes.
The main body of the ceramic infrared heater is ceramic, a part of the surface is used as a radiating surface and a heating coil is integrated. For ceramic infrared heaters, a thermocouple can also be fixed adjacent to the thermal conductor.
The ceramic infrared heater was invented by Elstein-Werk. The basic model of the cone-shaped ceramic infrared heater was patented on March 24, 1949. At the same time, a ceramic infrared plate heater was successfully developed to realize a large area of infrared heating surface. On March 8, 1950, Elstein-Werk obtained the patent right for ceramic infrared plate heaters. Ceramic infrared heaters are widely referred to as "El Transmitter", which is now used as the common name for ceramic infrared heaters.
How to judge the pros and cons of ceramic infrared heaters from the surface? The following methods allow us to make preliminary judgments.
1. Surface average power density
The higher the average surface power density can be achieved, the better the performance of the heater.

2. Limit temperature
The higher the temperature limit, the better the temperature resistance. Therefore, the longer the service life at the same temperature, the better. The higher the limit temperature, the better the performance of the heater.
3. Weight
Generally speaking, the lighter the ceramic heater of the same model, the higher the heating efficiency.
4. Heating and cooling performance
The quicker the temperature rise and fall, the better the heater performance.
5. Service life
Service life is an important indicator of heater performance parameters. The longer the service life, the better its performance.
6. Energy saving effect
Obviously, the better the energy saving effect, the better the heater performance.
7. Consistency
The higher the consistency of the parameters (temperature rise and fall performance, weight, etc.) of the same type of heater, the better the performance of the heater.
