Features
- Water-cooled or non-water-cooled bearing and turbine housings are available. The water-cooled housings contain coolant passages, so the turbocharger dissipates heat well even after an emergency engine shutdown, which improves reliability under extreme operating conditions.
- Water-cooled bearing and turbine housings effectively lower the turbocharger surface temperature, suiting applications with high comfort requirements.
- A wider choice of compressor and turbine specifications meets the matching requirements of turbocharged engines for all applications.
- High efficiency, comfort, reliability and safety make it well suited to gas engines, high-specific-power diesel engines and marine engines.
