Exhaust, Silencer, BESPOKE SYSTEMS, SEPARATORS from Halyard etc.

Fortunately, the heat problem can be overcome and noise greatly reduced by injecting water into the exhaust pipe just behind the engine. Thus we have what's known, quite logically, as a wet, or 'water injected' exhaust. There are other advantages. The reduction in temperature means that the exhaust system can be made of something other than steel, saving considerable cost and weight and reducing vibration. Special rubber exhaust hose can be used to join straight lengths of tubing, and in smaller boats it can make up the entire exhaust run. Exhaust hose is also useful as a flexible joint between the engine and the exhaust system proper.

WATER INJECTION HIGH RISERS

The achievement of effective cooling patterns in water injection elbows/sprayheads is an art. They must work at full power but still be effective at low revs when the water pump output is reduced.

We design and produce beautifully crafted modular high-rise injection systems for simple installations, or complex and sophisticated structures which must drop straight into position on craft thousands of miles away. Each one is the product of our design team working carefully with the customer.

HALYARD Top In Top Out Lift Silencers H001671

Top In, Top Out Lift Silencers - up to 50% noise reduction
In many applications a top inlet unit will be easier to use. The noise result and cost are the same as the side inlet units, and the same rigorous quality tests apply.

HALYARD Bronze Siphon Breakers H000566

The bronze used in our siphon breaker is Silicon Brass C87800, ASTM B176 , ASTM
ZS144A. This contains no zinc. Siphon breakers containing zinc may corrode,
particularly if the vessel's anodes are corroded and the siphon breaker is electrically
connected to this - perhaps by re-inforcing wire in the rubber water hose. Silicon brass
is also a superior material as it will resist water erosion. As water flows through the
siphon breaker erosion wear will occur, and silicon brass is better able to cope with
this than materials containing nickel or zinc. The use of this material accounts for the
high cost of our Siphon Breaker, but ensures the best possible material for the job.
The U bend on the top of the unit will emit water occasionally. This can be drained
overboard or into the bilge, but the hose used must not under any circumstances be
immersed in water at the bottom end, or the water will siphon back up the system -
potentially into the engine.

HALYARD Exhaust Alert H000419

THE EXHAUST ALERT SYSTEM

The Halyard Exhaust Alert works with a 12 volt or 24 volt supply.
It has three main components:

Sensor
A stainless sensor which screws through a 10mm hole in the exhaust hose, placing a temperature sensor right in the gas flow about 100mm (4") behind the engine. Up to three sensors can be used, covering twin engined craft and generators.

 

Junction Box
The junction box mounts in the engine space. This compact unit (75mm x 105mm) fits on a bulkhead in the engine space. Wires from the sensors and the helm display connect to it. It connects to the power supply (which must be live only when the ignition is turned on). A fuse is fitted for protection, and so that the system can be disarmed.

 

Helm display
This neat display (70mm x 35mm) fits near the helm and has a ready light, with warning lights for each engine and a small buzzer. A 120dB siren can be connected. The display self-tests when the engine is turned on, flashing the lights and sounding the buzzer. If the sensor overheats the relevant light will flash and the buzzer will sound. A tiny button allows you to shut down the buzzer.

A special system is also available without a helm display – a neat OEM kit which experts can wire into their own systems.

Halyard Stainless Steel Exhaust Thru-hull Flapper H002524

When the Halyard Exhaust Thru-Hull Fitting was designed, we set out to achieve a make of product which was infinitely stronger than the plastic and GRP units on the market – and tougher than most stainless units.
The Halyard Thru-Hull uses 3mm thick 316 stainless to ensure that the risks of damage when manoeuvring a craft are reduced to the absolute minimum. All units are designed so that the flap, at rest, is shrouded by the stainless rim to prevent damage if the vessel nudges a harbour wall.

Through Hull Fittings – Neoprene Flap
Units to accept exhaust hose up to and including 100mm (4") hose have neoprene flaps. Each has a really generous tail allowing "T" bar exhaust hose clamps to be used to secure the hose. Smaller sizes have 3 countersunk fixing holes. The 90mm and 100mm (3.5" and 4") units have 4 bolt holes and a bolting flange which fits right around the unit inside the hull.
Through Hull Fittings – Stainless Flap
Units from 125mm (5") upwards all have stainless flaps lined with neoprene. All have tails with plenty of space to use proper "T" bar clamps to secure the hose. Between 4 and 8 bolt holes are provided and all units have bolting flanges to fit around the unit inside the hull. Sizes to suit up to 300mm (12") hose are currently manufactured, and they are a normal stock item up to 254mm (10").
