Silicon nitride ceramic glow plugs are used for diesel engine start-up preheating and ignition of various high-temperature gases. This product uses silicon nitride ceramics as the base material of the heating part, which overcomes the problems of metal sleeve-type glow plugs, such as not resistant to high temperatures, short service life, and long pre-heating time . The following is the detailed information of our products: Electrical properties *Rated Voltage：8V，12V，16V，18V，24V *Frequency：50/60HZ *Rated power：35W～750W Advantages: Long service life: Service life reaches 15000 hours; Power on and off times: 105 times; Fast preheating: when the preheating temperature reaches 1000°C, the preheating time is 3-5 seconds; Good low temperature startup performance: reliable startup at -30°C; High temperature strength:suitable for high-speed diesel engines and high- temperature ignition devices.
