INNOVACERA supplies custom silicon nitride (Si3N4) hot surface igniters for gas furnaces, boilers, water heaters and industrial burners. Designed for fast heat-up and repeated thermal cycling, each igniter can be configured by voltage, power, heated-zone geometry, mounting structure, lead wire and connector.
Introduction to Silicon Nitride Hot Surface Igniters
Silicon nitride (Si3N4) hot surface igniters provide safe, reliable ignition for gas-fired equipment including furnaces, boilers, water heaters and industrial burners.
-
Precise Ignition Timing
After the igniter is energized to reach the ignitable temperature, the combustible mixture is introduced. This precise timing eliminates the gas leakage and deflagration risks associated with conventional ignition methods.
-
Wide Adaptability
The hot-surface ignition method adapts to variations in gas type, composition, air-fuel ratio, temperature, humidity, and oil contamination.
-
Reliable Operation, No Electromagnetic Interference
The igniter operates quietly without deflagration and produces no electromagnetic interference with other electrical appliances.
Features of Silicon Nitride Hot Surface Igniters
Silicon nitride hot surface igniters offer significant advantages over traditional ignition technologies:
- Compared to metal heating wires, silicon nitride igniters offer higher temperature capability and longer service life. Unlike silicon carbide heating elements, silicon nitride is dense, robust, and does not require special moisture protection.
- High operating temperature, fast heat-up response, compact structure, and extended operational lifespan.
- INNOVACERA holds core intellectual property rights and multiple invention patents for silicon nitride ceramic heating elements.
- Operating voltage ranges from 4V to 240V; power ratings from 10W to 300W. Applicable to ignition and heating of gas and fuel oil equipment across residential, commercial, and industrial settings.
