Advantages	> Ready to fit solution: High temperature heating element in temperature-resistant ceramic socket
	> Air can flow through and around inside and outside of heater
	> Element temperature: over 1000 °C in permanent and alternating operation, for a short time up to 1200 °C
	> Lifetime up to 100,000 heating cycles, depending on operating conditions
	> Oxidation and corrosion-resistant
	> Ignition through air heating: Due to extremely high heater temperature and ideal     geometric conditions, air is heated in a very short time to very high temperatures
	- the ideal ignition blower!
	> Igniting wood chips, firewood, coal bricks or other biomass (corn, etc.) is possible.

 

Pellet Igniter Supplier 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

Ceramic Igniter Concrete applications:
