Our staff travel all over the world We can help create a whisper-quiet looking at generator and propulsion generator exhaust on a 50m yacht to engine installations, and work with run all night with no disturbance to the naval architect, yard, operator and guests on deck, or we can produce a owner to create exhausts systems which system on a working ferry which will will achieve the desired results. give low noise levels at a commercial work with you by Email, fax or phone to achieve the result you need.

GRP AS A SILENCER MATERIAL We use GRP as the principal material in components used in the wet sections of our exhaust systems. Specialist resins allow us to build systems for the operating temperatures required, and GRP avoids the corrosion and noise EXCELLENCE IN EXHAUSTS problems of stainless steel. Our products are made from GRP filament wound tube, wound on our own computer controlled machinery and then assembled by craftsmen with years of experience in the lamination of complex sub-assemblies which must fit precisely into complete systems. 3

HMI SILENCERS We manufacture each silencer as a is given to achieving the accuracy of bespoke unit. 90% of our production angle and dimension agreed between is dedicated to individual craft. Each design staff and client to produce silencer is built by a team of two systems which will fit precisely in the craftsmen working to an ISO9001 given space. Inlets and outlets are accredited quality management system, skillfully positioned to couple to the and to the requirements of the major engine and to the rest of the exhaust classification societies. Careful attention system. Each completed...

HMI 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 EXCELLENCE IN EXHAUSTS 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 gasses can even exit up the funnel - achieving noise levels which are effectively inaudible against...

PARTS TO MAKE THE SYSTEM From humble hose clamps to sophisticated silicon bellows and bends to absorb vibration, Halyard carries the stock to supply every part of the exhaust from the engine to the outlet. Dry silencers too, for the ultimate result where a dry silencer precedes the water cooling, silencing and separating systems. Hose, GRP exhaust tube, siphon breakers, clamps,transom outlets, bellows, rubber shock mountings, heat protection jackets, rubber and GRP bends and elbows. We can help the customer specify parts to form a complete system, with every component part, delivered...
