Unison ignition systems are the most advanced in the industry. We are unmatched in our ability to engineer and integrate all components of the ignition system. We bring value to customers through our ability to work closely with our customers to create custom solutions to the most difficult problems.
Unison exciters are available for virtually any main propulsion or APU engine. All meet or exceed Mil Spec standards, are qualified by the OEM and are FAA-PMA approved for direct support to aftermarket customers. Unison's solid state exciters include built-in diagnostics and can communicate with even the most sophisticated FADECs for added reliability and greater safety.

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.
Each Unison ignition lead has the smallest diameter and lightest weight consistent with the application and performance profile. Conductor wires are mated with gold-plated contacts to lower resistance - a vital factor in high-cycle use. And Unison meets your more specialized requirements, too, with products like magnesium oxide leads that can withstand temperatures up to 1200 F.
