Growth in the maritime and offshore industries is pushing up demand for specially designed smoke and fire control products including Ruskin’s range of A-60 marine dampers. The dampers are available with galvanised casings and 430 grade stainless steel blades or, as an option, in 316 grade stainless steel casings and blades. They satisfy the rigorous corrosion resistance and vibration control standards required by all international maritime testing agencies. They are corrosion tested to BSEN 60068-2-52 (severity 2 conditions) and vibration tested to BS EN 60068-2-6. The A-60 is ideal for dry filtered air and is tested and approved for fitting to class A-60 divisions (bulkheads and decks), when suitably insulated. The A- 60 damper has undergone extensive fire testing in single and multiple arrangements. Actionair recently supplied more than 150 of these dampers to the largest and most expensive private yacht in the world. The Azzam was launched last year and, at 180 m (590 ft) in length, she has pushed the Eclipse yacht of Chelsea FC owner Roman Abramovic into second place. Azzam is larger than many ocean going liners and is owned by Sheikh Khalifa bin Zayed al-Nayan, President of the United Arab Emirates and Emir of Abu Dhabi. The stainless steel A-60 fire dampers were supplied along with a number of galvanised units – all complete with actuators. Actionair also provided a number of Aeroseal air control and shut off dampers with spring return motors. The dampers were incorporated in steel bulkheads and decks on the Azzam and tested to the Marine Fire Resistance Test in accordance with IMO resolution A754 to provide fire control for up to one hour.
