Mitsubishi MET Turbochargers
PJ Diesel is an authorised After-Sales Service provider for Mitsubishi MET Turbochargers.
We are authorized by Mitsubishi Heavy Industries Ltd. (MHI) in Japan as an After-Sales Service provider for their range of Mitsubishi MET Turbochargers. This includes maintenance, repair and reconditioning of all parts and components by service personnel trained by MHI for Mitsubishi MET Turbochargers.
MHI dates back to 1884 and started producing turbo chargers for marine application in 1965. The current Mitsubishi MET Turbochargers range consists of the larger axial type MET-SC, MET-SD, MET-SE, MET-SEII and MET-MA versions, as well as the smaller radial type MET-SR versions. The design philosophy of MHI is based on the three “E”s – Economy, Easy maintenance and Efficiency – and is consistently pursued in the continuous development of the turbochargers.
MET turbochargers are being used on all major engine types, e.g. MAN B&W, Wärtsilä and MHI two-stroke engines.
The Mitsubishi MET Turbochargers -MA turbocharger is the latest addition to the MET range, introduced in 2004, and is the latest version in an evolution of the MET-SB turbochargers introduced in 1980, over the MET-SBII, MET-SC, MET-SD, MET-SE and MET-SEII versions. These turbochargers have all utilised a non-water cooled internal bearing arrangement. The unique two-piece detachable gas inlet casing, introduced in 1980 to facilitate easy maintenance, has remained in its basic design, but optimised with regards to gas flow and weight. Mitsubishi MET Turbochargers efficience has been further improved with the MET-MA version, by minor modifications to the turbine blade profile – compared to the MET-SE and MET-SEII versions. The gas outlet casing design remains largely unchanged, but computational flow analysis have resulted in slight design changes to improve the turbine performance across the whole load range.
A special version of a Mitsubishi met turbochargers the MET83MAG, is a hybrid turbocharger, with a built in generator. Introduced in 2010, this hybrid turbocharger can generate up to 754 kW of electric power at 9,500 RPM. It can also substitute the function of an auxiliary blower, when used as an electric motor, to enhance the engine performance at low load – where the engine power does not result in sufficient exhaust gas for a good turbocharger performance. This turbocharger does enables reductions in fuel consumption and CO2 emissions.
The radial type smaller MET-SR turbochargers cater for the 400-2,900 kW power range. MET18SRC, introduced in 2006, is the latest and smallest turbocharger in this series, being suitable for the 400-930 kW power range.
