EXHAUST WATER SEPARATION<br />
Halyard developed the concept of <strong>exhaust</strong> <strong>water</strong><br />
<strong>separation</strong>, and now designs and produces<br />
systems for engines ranging from small generators<br />
to mighty power providers on superyachts and<br />
commercial craft. Fitting a <strong>water</strong> separator into the<br />
<strong>exhaust</strong> replaces the gooseneck, and removes the<br />
<strong>water</strong> once it has done its cooling job, draining this<br />
quietly away below the hull. Back pressure is<br />
reduced dramatically, and the system stops the<br />
sploshing noise which accompanies every marine<br />
engine running in harbour - or on a generator<br />
sploshing away in a quiet haven somewhere, to the<br />
fury of nearby boats.<br />

NOISE RESULTS<br />
The <strong>exhaust</strong> from most generators,<br />
using Halyard’s lift silencer allied to<br />
Halyard’s <strong>water</strong> separator, is effectively<br />
inaudible in all but the quietest<br />
environments. Not only this, but <strong>water</strong><br />
<strong>separation</strong> dramatically reduces engine<br />
back pressure. This allows huge design<br />
flexibility for propulsion engines as well as<br />
generators – particularly on larger yachts<br />
with long and tortuous <strong>exhaust</strong> hose<br />
runs from the engine to the stern.<br />
Test using 50hp marine diesel<br />
The new Millennium Separator range uses<br />
the knowledge acquired during 15 years of<br />
development work by Halyard. Each<br />
model was carefully and extensively tested<br />
before the sophisticated production<br />
tooling was commissioned, allowing bulk<br />
production to reduce the cost.<br />
The new Millennium Separator range<br />
achieves seven vital objectives:<br />
• The unit is reversible – it can be<br />
positioned pointing right or left.<br />
• Most have a choice of horizontal or<br />
vertical outlet.<br />
• Outlet is at maximum height,<br />
facilitating safe <strong>exhaust</strong> design.<br />
• No joints or seals – the one-piece unit<br />
removes the risk of leaks.<br />
• High melt point. Although the<br />
separator is fitted behind the silencer,<br />
the high temperature material<br />
minimises the risk of melting in an<br />
<strong>exhaust</strong> overheat situation.<br />
• Effective <strong>separation</strong>. Water <strong>separation</strong><br />
is almost 100%, apart from<br />
condensation in the dry hose run<br />
behind the separator.<br />
• World-beating value for money.<br />
Halyard’s <strong>water</strong> separator range is used<br />
by boat builders and generator<br />
manufacturers throughout the world, on<br />
generators up to 500kw. The Millennium<br />
Separator range is designed for<br />
production boats with generators up to<br />
approximately 40kw.<br />

SYSTEM DESIGN<br />
Good <strong>exhaust</strong> design depends on the<br />
engine position relative to the <strong>water</strong>line.<br />
A typical generator <strong>exhaust</strong> leaves the<br />
engine and drops to a lift silencer, then<br />
rises to the <strong>water</strong> separator mounted well<br />
above <strong>water</strong>line. This forms a high point,<br />
or gooseneck, in the system. The drop<br />
from the engine, and the high point,<br />
protect the engine from sea<strong>water</strong> coming<br />
in through the outlet when the engine is<br />
stationary. The layout is vital to protect<br />
the engine from sea-<strong>water</strong>. The Fitting<br />
