BLK silicon nitride
hot surface igniters.
Our highest-volume product line. A single Si₃N₄ heating core engineered for 100,000+ thermal cycles and 3-second heat-up, available in 12V, 120V, and 230V variants. UL Recognized and CE marked — a drop-in replacement for Norton, White-Rodgers, and Robertshaw hot surface igniters.
BLK-HS series — 6 models.
All six models share the same Si₃N₄ heating core. They differ in voltage, mounting configuration, and lead-wire setup. Custom voltage and geometry available with a 5,000+ unit MOQ.

180,000 units/year, −38% warranty returns, 7-year partnership.
One of our longest-running OEM partners switched from a European competitor's alumina igniters to BLK-HS series Si₃N₄ in 2018. Warranty returns dropped 38% in the first 12 months; cold-start failures (sub-zero installs) dropped 32%. Now in year 7 of supply.
- −38% Warranty returns vs prior
- −32% Cold-start failures
- +22% Avg igniter service life
- 180K/yr Current production volume
Certified for NA & EU markets.
BLK ships into 42 export markets. Below is the certification scope for the standard series — custom-voltage variants outside approved configurations require additional certification testing, which we coordinate.
