Ceramic Pellet Igniter Information

Ceramic Boiler Igniter surface can reach a permanent working temperature above 900℃;Since air can through and around inside and outside of the heater tube. Heat can be transferred from both inside and outside of the heater element. Igniting wood chips, firewood, coal bricks or other biomass fuel.

> Model No.: 90105
> Dimension: 90*OD10.5*ID6.5mm (Or Customized)
> Voltage: 230V
> Power: 255W
> Lead wire: 300mm / 400mm / 500mm / 900mm (Customized is accept)

Alumina Pellet Igniter Advantages

1) Higher temperature, about twice of traditional metal sheathed heater;
2) Shorter ignition time, about 60~90 seconds
3) Electrically insulated with no exposed electric contacts
4) Wear and corrosion resistance
5) Long life time
6) Easy to install and replace
7) Long-lasting (non-aging). Tested to 100,000 cycles.
8) 800~1100°C at steady-state temperature. Impervious to oxidation and corrosion.
9) Ignite kerosene, wood chips, split logs, coal briquettes or other biomass, corn, etc.







Alumina Ceramic Heater Design Structure

Ceramic Heaters are manufactured by printing resistors on alumina shees,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
