The umpteen benefits of an SCR system (for ships)

– NOx reduction that meets or exceeds IMO Tier III limits
– Can be installed in new ships and as retrofit
– Easy to maintain by the crew

Emigreen® specializes in equipping four-stroke engines with a rated speed greater than 600 rpm with a modern SCR system capable of meeting current requirements.

We can equip Tier II engines with an external catalytic converter, such as the Emigreen® MINOx SCR system, which reduces levels of NOx emitted by marine diesel engines to well below IMO Tier III limits. Which makes the refit a sustainable solution. The refit improves the quality of the air we breathe, which makes the refit a sustainable solution.

Diesel combustion engines emit nitrogen oxides (NOx).

While not immediately harmful at normal environmental concentrations, these poisonous gases are ultimately detrimental to human, animal and plant health. In hot weather, higher levels of NOx pollution contribute to the formation of smog.

An SCR system helps prevent this by significantly reducing nitrogen oxide emissions.

Our SCR catalytic converter reduces nitrogen oxide emissions.

1: A urea solution such as AdBlue is injected (sprayed) into the exhaust system
2: The water evaporates and the urea is converted into ammonia
3: The ammonia reacts with the nitrogen oxides in the exhaust stream
4: As they pass through the catalytic converter, the gases are converted into inert nitrogen and water vapour.

The Emigreen® SCR system is more compact than the alternatives.

Our systems can be cleverly tailored to make the best use of the available space. The integrated silencer in an Emigreen® SCR unit eliminates the need for the existing silencer.

This makes it possible to do more in less space. Our SCR solution can also be installed as a retrofit, even in spaces that look too small.

And where the ship design allows, one of our standard systems may be the most effective solution.
