Did you know
- The Accelleron A100-L series of single-stage turbochargers was first introduced in 2009 by ABB Turbocharging, which later became Accelleron in 2022. This series builds upon the legacy of the TPL-B series, which was launched in 1999.
- The A100-L is part of Accelleron's A100/A200-L series, designed for low-speed two-stroke marine engines, covering an output range from 3,000 kW to 28,000 kW. It sits alongside the A200-L, which offers a 30% increase in volume flow, and the A100-M and A100-H models, which are designed for medium and high-speed engines, respectively.
- The A100-L is chosen for its high efficiency, high pressure ratios, and wide compressor maps, which enable compliance with IMO Tier III NOx emissions limits and market-leading fuel efficiency. Its design prioritizes reliability, long maintenance intervals, and low life cycle costs, making it a cost-effective long-term investment for operators.
| Model | Engine Type | Engine Speed | Turbocharger Efficiency | Pressure Ratio (at full load) | Volume Flow (vs TPL-B) |
|---|---|---|---|---|---|
| A100-L | Two-stroke | Low | Up to 75% | 4.7 and above | Up to 15% more |
| A100-M Axial | Four-stroke | Medium | 70% | Up to 5.8 | N/A |
| TPL-B | Two-stroke | Low | N/A | N/A | Benchmark (older model) |
