Advantages

(1)Long lifetime: airproof structure ; the condition of deformation .can’t exit

(2)Temperature rise quickly

(3)Excellent insulation 

(4)Energy efficient and thermal conductivity super—heating simultaneously both from inside and outside

(5)Small  and compact

(6)Equalized heat distribution and high power density.

(7)High cost performance.

Ceramic heater technology benefits:
* A fraction of the energy consumption compared to conventional element heater
* Long-lasting (non-aging)
* Time to ignition 60~90 seconds
* Tested to 100,000 cycles
* Easy to install and retrofit
*100°C at steady-state temperature
* Impervious to oxidation and corrosion

Alumina Ceramic Heater Design Structure

Ceramic Heaters are manufactured by printing resistors on alumina sheets,being laminated and sintered into
one pieces.

* Types:
■ Rectangular alumina ceramic heating element
■ Round shape alumina ceramic heating element
■ Rod shape alumina ceramic heating element

■Tube shape alumina ceramic heating element
