RH-series turbochargers are developed, marketed and manufactured by IHI America under license from IHI. IHI and IHI America have a long, successful history in the manufacture of quality, reliable high-speed rotary machines.

The excellent performance and reliability of the RH-series turbochargers represents the application of state-of-the-art technology to meeting today's market needs. These highly regarded turbochargers have found application in the automotive, heavy truck, marine, construction machine and industrial engine markets.

These turbochargers were developed to achieve the following important characteristics.

  1. High reliability: Design for optimum bearing stability, oil seal performance, and thermal resistance in conjunction with strict quality control ensure high reliability and excellent field life.

  2. Superior performance: Use of advanced aerodynamic design for turbine and compressor wheels along with minimized mechanical loss and low inertia generate superior performance including high flow rates, wide operating ranges, and excellent response.

  3. Compact design: The RH-series is designed to minimize size and weight while maintaining the required strength. This allows for minimum package requirement for a given application.

  4. Broad application: RH-series includes a wide variety of models for maximum application range.

Technical support for customers of the IHI America RH-series is provided through a worldwide network covering R&D, design, marketing, manufacturing and quality and evaluation.

RHS and RH series turbochargers

RHS and RHZ series turbochargers incorporate advanced technologies developed by IHI. These turbochargers were designed to meet today's stringent market requirements.

The RH series are available with mixed-flow and radial-flow turbines and an advance bearing structure for automotive turbochargers. They are designed to satisfy increasingly strict emission regulations while achieving high-pressure ratios, long service life and high efficiency.

RHS and RHZ turbochargers are designed to be interchangeable with the preceding RHF series. Development of the RHS and RHZ series enabled further downsizing, resulting in higher performance in a smaller package.
