Water separator
The benet of a water separator (E1) in addition to a water lift silencer, is that it separates the water from
the water/gas mix and discharges below the waterline (E3) thus avoiding the often irritating spluttering noise
associated with water cooled generators, especially in a quiet marina. A water separator also reduces exhaust
back pressure in long exhaust runs.
Warning! Sailing yachts can present special problems when considering the amount of heel and therefore
care must be taken when designing the system.
When designing the exhaust system for sailing yachts the predicted heel and any engine installation offset
from the centreline must be taken into account.
The designer may include in the system a gate valve or sea cock (E2), if there is any likelihood of the engine
being at risk in extreme heel conditions as a precaution.
