Accelleron

🇨🇭 Switzerland Industrial Components

High-power turbocharging, fuel injection and digital optimisation technologies for marine, energy, rail and off-highway engines.

Accelleron is the current public brand of the former ABB Turbocharging business. The company is headquartered in Baden, Switzerland and became an independent publicly listed company following its spin-off from ABB in 2022. Accelleron’s heritage reaches back to Brown Boveri’s delivery of the world’s first industrially manufactured turbocharger in 1924. The profile should preserve "ABB Turbocharging" for search continuity but use Accelleron as the current display name.
