Halyard launches new design of water separator at METS

Halyard, Europe’s largest designer and manufacturer of specialist marine exhaust systems will be launching a new design of water separator at this year’s METS show. The British company and 2006 winner of the prestigious Queen’s Award for Innovation, has invested £25,000 in the development of the new water separator which will be moulded using high temperature polypropylene – renowned for its excellent water and chemical resistance.

Water separators are fitted into wet exhaust systems after Halyard’s silencer, which is built to take the high temperatures which can occur if the cooling water intake blocks. The unit separates the cool gases and water, dramatically reducing noise and back pressure. Water then drains silently away below the waterline with the gas exiting above waterline. Tests have shown a 10 dB (a) reduction in noise over conventional systems – less than a quarter of the original noise.

Developed from Halyard’s existing two inch moulded water separator, the company’s new unit has been specifically created to comply with stringent new emission standards that make it necessary for new marine generators to be manufactured with three inch exhaust outlets. The new standards affect generators from around 18kW sold in Europe, which means that most manufacturers will adopt the standard for worldwide sales.

The separator has been tested with generators with raw water flow rates of up to 62 litres per minute, being the highest coolant flow of any generator with a three inch exhaust. In time, Halyard will raise the 62 litre limit as practical experience increases. In addition, fibre glass models of the new separator have been tested extensively against a wide variety of generators to ensure that the new design is capable of handling all combinations of gas and water flow.

The new water separator will reduce the cost to the end user by up to 40% against Halyard’s original three inch water separator which was constructed using Glass Reinforced Plastic (GRP).

The new water separator is being manufactured in the UK by Halyard, the only company in the world able to manufacture an entire exhaust solution in-house and also the only company worldwide to have Lloyd’s Type Approval on its entire range of GRP exhaust components, hose and silicone couplings.
