Did you know
- Accelleron, formerly ABB Turbocharging, has a heritage in turbocharging dating back to 1924 with the delivery of the world's first industrially manufactured turbocharger. The VTR series itself is a predecessor to the TPL generation of turbochargers.
- The VTR 454 is part of the VTR series, which is designed for two-stroke low-speed and four-stroke medium-speed heavy-duty diesel and gas engines. Within the VTR series, the '4' in VTR 454 indicates it belongs to the VTR..4 series, which includes models like VTR 214, VTR 254, VTR 304, VTR 354, VTR 564, and VTR 714.
- The VTR 454 is known for its robust construction and proven reliability, making it a popular choice for marine propulsion engines, especially at part load, and in stationary power plants. Its design with easily accessible external bearings simplifies and speeds up servicing, as the bearings can be removed without dismantling the compressor wheel or air and gas pipes.
| Model | Engine Type | Power Range (kW per turbocharger) | Compressor Pressure Ratio (πc [-] at MCR) |
