The VTR is the predecessor to the TPL generation of turbochargers, designed for two-stroke, low-speed and four-stroke, medium-speed heavy-duty diesel engines with an output range of approximately 700 kW to 18,500 kW per turbocharger. VTR has a proven track record on marine propulsion engines, especially at part load, and in stationary power plants. Its modular construction makes assembly easy.
