Silicon Nitride Igniter
Modern silicon nitride igniter represent an upgrade over older silicon carbide furnace ignitors, offering greater durability and thermal shock resistance than their silicon carbide counterparts.
HVAC technicians can quickly assess the health of a silicon nitride ceramic HSI by disconnecting and measuring its cold resistance value without regard for polarity; 30-75 Ohms indicates an effective ignitor.
Fast Heating Response
Ceramic hot surface ignitors are the go-to electronic ignition systems in modern natural gas furnaces, acting like light bulb filaments when powered up with 120V to quickly heat up into an incandescent red hot surface that ignites gas. Hot surface ignitor systems eliminate the pilot flame required by older pilot systems while providing more consistent and safe operations, saving energy costs while increasing safety levels.
Silicon Nitride (SN) igniters are more durable than the silicon carbide igniters typically used in furnaces, making them an excellent upgrade choice for customers looking to increase the longevity and reliability of their gas appliances. However, when installing them properly they must ensure all surfaces they cover make contact with incoming gas – this requires replicating how a chrome ignitor was set up so as to avoid misfires and delayed ignition occurrence.
High Temperature Resistance
Igniters reminiscent of light bulb filaments can be found in furnaces to ignite gas inside. Their red-hot glow helps light the fire of combustion inside furnaces while their durability, quick heating capability and resistance against high temperatures make them popular options for other appliances such as water heaters, dryers and other machines.
silicon nitride igniter used in many newer furnaces can be tricky and fragile, requiring delicate handling when mounted properly to ensure they make contact with gas for ignition.
Use an ohmmeter or multimeter to disconnect the ignitor and measure its cold resistance (when disconnected). A reading between 30 to 75 ohms indicates good condition for an ignitor. If the reading falls outside this range or has no reading at all, replacement should be undertaken immediately as this could be one cause of no heat calls and represents an opportunity for upselling for HVAC contractors.
Long Lifespan
Modern furnaces rely on hot surface igniters to light the flame that travels through your system’s tubes and into your home, making ignitors an essential component for its efficiency and durability. Ignitors made of silicon nitride tend to last longer than their silicon carbide counterparts, helping reduce energy usage and utility bills in turn.
silicon nitride igniter are tough enough to withstand the rapid temperature shifts associated with furnace startup and shutdown cycles, making them suitable for OEM systems as well as retrofit kits for older furnaces.
Nitride spark plugs are tough and durable, capable of withstanding high temperatures while being resistant to abrasion – qualities which make them the ideal choice for use in communications networks, optical signal processing applications and cantilevers used on atomic force microscopes. Our SN igniters are manufactured to exact voltage and resistance specifications so as to be compatible with Goodman control boards and gas valves.
Easy Evaluation
silicon nitride igniter are used in gas furnaces and water heaters to light the burners used to provide heating. Their durable construction, high temperature resistance and quick heating response times make them the perfect solution.
Unfortunately, many HVAC construction technicians treat them in much the same manner as they treated silicon carbide style bulbs: by simply dropping them in, turning on their system, and leaving. Unfortunately, this often leads to no-heat calls which could have easily been solved by simply inspecting its ignitor for cracks or broken surfaces.
silicon nitride igniter have proven much less fragile than older models, and can easily be evaluated using a multimeter or an ohmmeter by measuring their cold resistance value (disconnected from any unit, without polarity). A quality ignitor should have a resistance value between 30-75 ohms; anything higher indicates brokenness that should be replaced immediately.
