How to deal
with soot?

Regeneration:
* Fuel
* Electrical spiral
* Additives
* Self regeneration
Nauticlean® By HUG engineering

How About

IMO rules push
engine suppliers
to reduce
NOx emission

Selective
Catalytic
Reduction
SCR technology can take out all NOx

Auxiliary &
Main engines

Technology is the same

The size and price of the
systems are quite different

Going green
is about making choices

Technology is available

Space & Budget
are needed to realize it

Low emission engines

New cleaning solutions

Different power source

The Ideal installation
“…in general to go “green” I suggest installing a
generator exhaust with soot filter, a catalytic
converter, and a silencer/separator.”
