ABB introduces the new A200-L generation of single-stage turbochargers for low-speed two-stroke engines.The A200-L’s compressor stage has been optimised to enable significantly more additional volume flow.
In comparison to previous models, the A200-L has up to thirty per cent additional volume flow, which to date is the equivalent to one size smaller in a series of turbochargers. This increase represents a leap in turbocharging technology.
World First
Michael Lok, General Manager Low Speed Segment, adds, ‘We are looking at a model that potentially makes no compromises on the three key variables efficiency, pressure ratio, and volume flow – used to measure performance in a turbocharger. No one has ever been able to do that, at least as far as I know. If we are able to achieve that with the A200-L, it will be an important contribution to the turbocharging industry.’
Higher Power Density
In effect, the power density of the turbocharger compared to other models is significantly higher. The turbocharger is often one of the heavier components to service on a ship, so the A200-L’s lighter design also makes it much easier to maintain.
Lighter and Smaller
The A200-L’s compacter frame makes it possible to use a smaller turbocharger on a wide range of two-stroke engines, thus a lower weight and more space, which in turn have a positive impact on service costs, a lower first cost and a lower total cost of ownership. And since less material is used to make it, the impact to the environment is also reduced.
‘The savings in service costs alone amount to at least 25 per cent in many models, and in some cases even more,’ says Arie Smits, Senior General Manager Global Turbocharging Projects.
First Commissions to Be Tested in May
The company has already sold its first commissions and is currently in production. The first turbochargers will be tested on engines at the beginning of May, prospectively.
