ETB (Electrical Turbo Blower) raises exhaust-gas pressure to overcome the pressure difference between exhaust gas and scavenging air receiver by actively controlling the exhaust gas flow; strategic step to bring development in-house; design focuses on cost-optimisation and compactness

MAN Energy Solutions has launched its new EGR (Exhaust Gas Recirculation) electrical turbo blower – designated ETB40 – at a ceremony in Shanghai attended by some 120 industry guests and hosted by its two-stroke licensee, CSSC-MES Diesel Co. Ltd. (CMD).

Simultaneously, CMD announced that it has placed the first order for the new blower in connection with the construction of several MAN B&W two-stroke 7G60ME-C9.5 main engines for newbuilding vessels.

Individual ETB40 units will be installed aboard each vessel as part of their main-engines’ integrated EGR system. The order also represents the first time that CMD has employed EGR technology for compliance with IMO Tier III regulations, having previously commissioned several successful SCR (Selective Catalytic Reduction) applications.

Ralph Klaunig, Vice President and Head of Turbocharger and Exhaust Gas Systems Sales, MAN Energy Solutions, said: “Our development of the ETB series is a strategic decision and a significant addition to our existing, proven EGR technology that will play an important role in maintaining IMO Tier III emission standards. This will enable customers to achieve sustainable value creation in the transition towards a carbon-neutral future. In taking this step, we are making use of our in-house turbocharger technology that features a significantly higher thermodynamic efficiency than previous designs.”

Klaunig continued: “The development of the ETB series is the next logical step toward complementing MAN Energy Solutions’ EGR IMO Tier III solution packages for customers, and to ensure that there is a significant cost-down on all major components. The key to success will be continuous development and to ensure that the ETB remains the most cost-effective blower on the market.”

Shuhei Kajihara, President of CMD, said: “First of all we are very proud to be the first Chinese EGR engine manufacturer. This was possible, because MAN and CMD worked closely together in finalising this first-of-its-kind project. Despite a challenging delivery time, the teams managed to perform really well. I especially appreciate MAN’s continuous updates about the latest stages of development and their support in our factory during installation and commissioning.”
