Ceramic igniters are extremely durable components designed to withstand harsh operating environments like high temperatures, thermal cycling and oxidation, making them the ideal choice for gas stove settings.
Hot zone 12, cold zones 14a and 14b and electrical leads 66a/66b are enclosed within a hermetic sealant material 72 that effectively prevents moisture from coming in contact with the igniter's electrical contacts. Cermoplastic material boasts dielectric strength multiple times greater than conventional potting cements for maximum protection against moisture intrusion.
Silicon nitride ceramic igniters are widely utilized in gas furnaces for quick and consistent ignition of the burner and optimal heating performance. Additionally, these igniters are widely utilized in water heaters and other residential heating systems due to their reliability in withstanding regular usage without cracking or breaking, thus decreasing service calls required for repairs or replacements.
Electrical contact portions of igniters should ideally be coated and completely enclosed in sealant material to form an hermetic barrier, with coating material consisting preferably of cerramoplastic material for ease of manufacturing by insert molding or batch processes.
Electrical conductors in ceramic bodies are embedded within temperature-resistant alumina ceramic, creating an extremely reliable product with the strength to withstand thousands of 132V voltage cycles before failing - far exceeding minimum requirements for any other type of igniter.
Champion ceramic igniters incorporate a resistive booster zone which limits current flow into the hot end, thus limiting non-thermal cycling and decreasing wear on your igniters while speeding start times and prolonging their lives. This feature reduces wear, allows faster starts, and extends their lives for increased longevity.
Wholesale ceramic igniters offer an affordable and reliable alternative to standard igniters, designed to withstand high temperatures and intensive use - perfect for heating systems! Their extended lifespan means lower replacement and maintenance costs over time.
Hermetic sealant compositions typically incorporate multiple materials. Sealants employed to encase igniter ends and electrical contacts typically include materials from among: alumina oxide; aluminum nitride; silicon carbide; boron nitride; molybdenum disilicide or combinations thereof. Cold zones 14a-14b typically consist of: semiconductor material such as doped or undoped silicon carbide as well as an insulator material.
Oft times igniters need replacing due to burnout or failure, making the task simple with the necessary tools and knowledge. Make sure that you unplug your oven or gas line first as a precaution; remove and install your new igniter with ceramic wire nuts (most igniters have two wired versions which you can cut away before plugging back in with new ones); most igniters come equipped with two plugs so they're easy to splice into existing plugs using an adaptor; or cut existing wire plug off and splice into existing plugs when swapping out old ones; most come equipped with two wired versions which just cut one off before connecting it all works as intended if necessary.
Silicon nitride hot surface ceramic igniters work like light bulb filaments, rapidly heating when electric current passes through them and reaching their proper temperatures to open gas valves and ignite burners.
These components are resilient to oxidation, thermal cycling and other environmental stresses that can damage other materials. Furthermore, they flex and bend without breaking - an ideal choice for wood pellet stoves and other combustion systems as they require less energy to reach ignition temperatures while offering long service lives.
Ceramic igniters are extremely hard-wearing components, capable of withstanding harsh operating environments due to their superior oxidation resistance and exceptional thermal cycling capacity. Furthermore, their incredible flexural strength enables them to bend without breaking.
Silicon nitride and silicon carbide ignitors can withstand rapid temperature shifts during furnace startup and shutdown, helping them resist thermal shock that might otherwise cause damage or malfunction to other components and cause malfunctions.
As soon as the igniter receives a signal from your Furnace controller, it begins glowing to heat before producing a spark that ignites the gas connected to your heater. Over time, however, its durability will wear down over time and eventually require replacement in order to keep your furnace functioning at peak performance. When its starting flame takes longer than usual to ignite and heat up, that indicates its end of lifespan and replacement - easily done using an ohm meter or multimeter to measure voltage on its wires attached.
