We build high tension and low tension turbine igniters for aircraft main propulsion engines, auxiliary power units and a wide range of turbine engines for industrial applications. Unison turbine igniters are built with induction-fused glass seals to resist high combustor pressures, and may include exotic metal tip designs (e.g., Iridium, Hastelloy X) for high temperature performance and longevity. Optimized semiconductor geometry and composition resist spark erosion even in the most demanding continuous duty service. Unison anti-wear and thermal finishes stand up even under vibration and heat extremes.
