ABB TURBOCHARGING LAUNCHES NEW COMPACT TURBOCHARGER

The turbochargers are extensions of ABB’s proven and reliable single stage A100-L and A200-L designs, and combine the previous turbochargers’ best in class performance and wide compressor maps with a smaller frame size and enhanced rotor component technologies.

ABB is in discussions with a number of interested parties. These turbochargers will be produced in its production facility in Switzerland, China and by the company’s licensees in South Korea.

Digital SIKO, a digital exposure-based functionality to rotor assessment, enabling rotor exchange intervals to be managed according to condition is also available on these turbochargers.

The reduction in size will lower maintenance costs, while the improvement in efficiency will reduce fuel costs, resulting in an overall reduction in the total cost of ownership.

Alexandros Karamitsos, head of global sales for Product Line Low-speed Turbocharger, ABB commented: “We believe further focus will be placed on turbocharger efficiency in the future, alongside higher compressor pressure ratio demands, to enable two-stroke engines to reach their full potential. Our A255-L and A260-L turbochargers will support this demand, delivering the highest levels of turbocharger efficiency and power density while enabling small-bore two-stroke engines to achieve lower fuel consumption, and complying with latest emissions regulations.”

The compact design makes the turbocharger easier to mount in in modern, space-optimized engine rooms, which is a particular consideration for vessels below 40,000 dwt.

Karamitsos continues “The A255-L and A260-L turbochargers are designed to operate on all fuel types and on engines specified for both IMO Tier II or Tier III emissions levels. Similar to other turbocharger products in our A200-L series, a full range of matching components will be available to ensure an optimized on-engine specification. Our drydock-to-drydock service concept will also be available for these turbochargers.”

Due to the significant efficiencies achieved, the new A255-L and A260-L turbochargers can reduce the energy efficiency design index (EEDI) of smaller merchant vessels in the size range of 10,000- 40,000 dwt that make use of small and medium bore two-stroke engines.
