SILENCER SEPARATORS

We developed the art of water separation, for generators and propulsion engines, to end the noise created by water sploshing from the exhaust outlet. The technology removes the water from the system once it has done its cooling and silencing job.

In 1992 we were the first to build combined silencer separators dedicated particularly to large generators. Today Halyard designs and produces silencer separators which are so efficient that the dry gases can even exit up the funnel - achieving noise levels which are effectively inaudible against normal backgrounds.

Types of Exhaust Water Separator

Mid-Gen Separator

This larger separator is designed for use where the generators cooling water flow rate exceeds 40 litres per minute, and the generator exhaust is up to 90mm (3.5") diameter. Individual applications must be checked for correct sizing. It may also be used with propulsion engines.

Mid-Engine Separator

The mid-engine separator is an easy solution for most engines with exhausts from 60mm (2.5") upwards. Units are produced in batches using the same proven technology as Halyard silencers. The internal pipe work and body are both from Halyard’s tough filament wound tube, and every unit is pressure tested. The unit comes with differing body sizes to match the varying exhaust inlets. Two outlets are provided on most units so that yachts can have an outlet for both angles of heel.

Silencer:Separator

An example of a bespoke silencer:separator designed and built specifically for a Mediterranean super-yacht. This unit is part of a system which extracts all water from the exhaust, and allows the gas from a 200kVA generator to be piped up the main engine funnel. The fumes from the generator will then disperse silently, and well above the heads of those on deck below.

Production Separator

In 1993 sales of small Halyard separators reached a point where more economic production had to be found. The MS series of separators represented a huge investment in injection mould tooling, which reduced the unit price to very modest levels by using a special high temperature polypropylene. Today the MS series covers a huge range of exhaust diameters, for generators and propulsion engines with cooling water flow rates of up to 40 litres per minute. The MS unit will remove all but a tiny trickle of water.

The Halyard Separator won the RYA British Nautical Award for Technical Innovation.
