Hot surface igniter for gas/fuel appliance

The ignition mode generally applied in Chinese household and industrial gas equipments is high-frequency ignition, while the ignition mode abroad has more and more applied to hot surface ignition.

Hot surface ignition completely eliminates many drawbacks of high frequency ignition, like the noise pollution, unsafe deflagration, poor ignition reliability and electromagnetic interference to the automatic control equipments.

SiC (Silicon Carbide) ceramic hot surface igniters have been commonly used for more than 25 years in US and EU markets of commercial / household air-conditioning gas devices. However silicon carbide igniters have the flaws of decentralization of hot area, frangibility and etc.

Le-mark’s hot surface Si3N4 igniters provide a novel and powerful solutions for ignition. Le-Mark’s igniters have eliminated the flaws of traditional ignition modes. 
Le-Mark’s igniters have the advantages: 
100% reliable ignition;
No interference
No gas leakage
High mechanical strength
Strong abilities of humidity resistance and thermal shock resistance
Do not need the special controller 
Complete replacement of SIC (Installation modes and thermal electrical characteristics)

Wide commercial and household applications cover gas air conditioner, gas air heater, dryer, range, cook top, pool or water heater, ignition of pyrotechnic effects, mosquito trap and etc.
