X52DF-2.1

X52DF-2.1

For gas and bulk carriers, Handymax tankers, feeder container vessels, RoRos and general cargo ships.

WinGD’s low-pressure dual-fuel technology is a sustainable propulsion solution that runs safely, reliably and efficiently on gas as a cleaner option over conventional heavy fuel oil or diesel oil. Further optimising the standard X-DF portfolio, WinGD now offers X-DF2.0 technology providing reductions to both fuel consumption and methane slip in gas mode. iCER – the Intelligent Control by Exhaust Recycling system, is the first application of X-DF2.0.
The X52DF-2.1 fulfils Tier III emission requirements without any external exhaust gas after treatment system when operating in gas and diesel mode.
