Parking heater element

${Details}

Product Overview


Our Silicon Nitride (Si₃N₄) Parking Heater Elements are advanced ceramic ignition components engineered specifically for the demanding environment of fuel-fired parking heaters. Designed to replace traditional metal glow plugs, these elements utilize the superior properties of high-performance Silicon Nitride ceramic to deliver rapid, reliable, and durable ignition.


Whether for truck sleeper cabs, RVs, marine vessels, or industrial machinery, our heating elements ensure your parking heater starts instantly, even in extreme sub-zero temperatures, providing consistent warmth without the risk of ignition failure.


Key Features & Benefits


Ultra-Fast Ignition: Silicon Nitride offers exceptional thermal conductivity. Our elements can reach 1000°C in approximately 2 seconds, ensuring immediate fuel vaporization and combustion.
Extreme Durability: With a high fracture toughness (more than double that of Silicon Carbide), these elements are highly resistant to vibration and thermal shock. They are built to withstand the rough conditions of mobile applications.
Corrosion & Oxidation Resistant: Unlike metal elements that can degrade or oxidize over time, the ceramic surface is chemically inert. It resists corrosion from fuel byproducts and combustion gases, significantly extending the service life of the heater.
High-Temperature Stability: Capable of continuous operation at temperatures up to 1350°C, ensuring reliable performance even during prolonged heating cycles.
Energy Efficient: The low thermal mass allows for rapid heat-up with lower energy consumption compared to heavy metal plugs, preserving vehicle battery life.
