Features
- Water-cooled or non-water-cooled bearing and turbine housings are available. The water-cooled bearing and turbine housing design provides good explosion protection and greater safety.
- Water-cooled bearing and turbine housings effectively lower the turbocharger surface temperature, suiting applications with high comfort requirements.
- Wide-flow-range compressor can be matched to all engine load characteristics.
- Extremely compact design makes the turbocharger easier to install and replace.
