SUPER SILENT" EXHAUST SYSTEM
In order to reduce the noise level of the generating set to a
minimum, an option to reduce the exhaust noise further
(especially exhaust water splashing) is an exhaust/water
separator. The exhaust/water separator allows the cooling
water to be ejected through a line (A) separate from the
exhaust fumes and also functions as a goose neck to
prevent
water
from
flooding
exhaust/water separator is mounted more than 600 mm
above the water level an additional goose neck is not
required.

If
the
If the through-hull exhaust outlet has to be mounted far
from the generating set (total length of the exhaust piping
from generator to top of goose neck (water separator) is
more than 3 m), an exhaust/water separator must
definitely be installed. The sea water from the separator
must then run down along the shortest possible path to the
through-hull outlet.
Only after the exhaust/water separator the exhaust hose
may have a length of over 7,5 m if the exhaust hose
diameter is also increased from 51 mm to 63 mm in order
to reduce the back pressure (ref. to fig. 14).
However water traps should be avoided as the fumes still
contains water and this should not accumulate in bends
(refer to fig 13). An additional outlet exhaust muffler close
to the hull outlet will help further to reduce noise emission.
