MAN Energy has launched its new electrical turbo blower (ETB) for the marine industry at a ceremony in Shanghai.

The new ETB is designed specifically to meet the International Maritime Organisation’s (IMO) Tier III emission standards, which are meant to cut the amount of nitrogen oxide (NOx) emitted by vessels.

The ETB is a core component of MAN Energy Solutions’ high-pressure exhaust gas recirculation (EGR) system that is designed to increase efficiency by controlling the exhaust gas flow and varying the blower speed.

It is the latest in MAN Energy Solutions’ eco-friendly maritime solutions. In September 2018 it unveiled a liquefied petroleum gas (LPG) engine, designed specifically for large vessels.

Speaking at the unveiling in Shanghai, Ralph Klaunig, Vice President and Head of Turbocharger and Exhaust Gas Systems, 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.

“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”.
