With its unique design, the Sirocco fan excels in performance and is a premium choice, being one of the best cabin fans in the marine market. In 1988, the Davidson Group was acquired by the fan and heat exchanger firm James Howden & Co (established 1854 by the Scottish engineer James Howden) to form Howden Sirocco Limited, today known as Howden UK. [3] Davidson's Sirocco Works were eventually vacated and in 2009 the property was demolished as part of the redevelopment of the Belfast Waterfront. The name of Davidson's former factory continues today in the Sirocco Works Football Club, a team formed in 1924 by works employees which continues to play today in the Northern Amateur Football League. The building was derelict and partially roofless at the time of survey in October 1994 but was otherwise in a reasonable condition. It has a small, lightweight, quiet, and energy-saving design. Dual-use 50/60 Hz. Items with an E at the end of the item number have a high-efficiency motor specification that meets the JIS C4212 specification. However, shifting this fan forward or aft would have placed the duct right down on top of the angled bulkheads of this "indentation".

This is very useful if you want the fan on for part of the night but don’t want it to run all night long. The Sirocco fan has three-speed settings, so you can adjust it to suit your needs. It also has preset timer settings. This means that it will turn off automatically after 3,6,9,12 hours, which helps to conserve energy. a b c "Samuel Cleland Davidson" (PDF). Heritage Group of the Chartered Institution of Building Services Engineers . Retrieved 30 November 2013. Have you got Peter Davis-Garner's modeling book? I was very impressed with the amount of detail he went into with his drawings. According to his drawings, two such ducts would have been seen in between the Lounge bay windows (that is one on each side), and another one along the fore outboard wall of the Reading and Writing Room (the latter not being on Olympic, and there is a Fr. Browne photo that shows this area from 1911 -- no ducting). Howden was established over 160 years ago. Over that period, many of the world’s best-known technologies, companies and products have become part of the Howden organisation.It has an innovative gimbaled design for 360° directional airflow across three-speed settings providing unmatched comfort.It is also ultra quiet, with four auto-off options (3, 6, 9, and 12 hours) for a restful night’s sleep. I believe that what you are calling a "corrosion hole" is actually where the duct passes through Titanic's lounge roof extension. No such opening would be found on Olympic because the Career [ edit ] Samuel Cleland Davidson with a huge centrifugal fan he designed and manufactured, probably for ventillating a mine shaft. The Sirocco Works on the River Lagan, Belfast, during demolition in 2009 For the already existing Sirocco users that are looking to upgrade the mounting footprint matches exactly for the new fans. For new users, the fan comes with double sided tape for easy install of the mounting plate The key feature of the fan is that it can be turned to direct the airflow in any direction. It also uses very little power, which is excellent because it means you won’t drain your batteries when you have it running all day.

Samuel Cleland Davidson became a Member of the Institution of Mechanical Engineers in 1888, and in 1921 he was knighted by King George V although too ill to make the journey to London for the ceremonials. A few months later Davidson died on 18 August 1921 in Seacourt, Bangor, County Down. He was buried alongside his wife, Clara Mary, in Belfast City Cemetery. [7] Why bifurcate when you can throw the duct either forward or aft of the frame? In the absence of GA detail showing some countervailing impedance I would have thought that would have been the chosen solution. The fan is a little noisy when it is set to high speed, but it is probably as quiet as a fan can be. Channel Islands; Inflatable dinghy price on request Channel Islands; Flares not available to ship at this time lounge roof was not extended outboard like Titanic but rather followed the line of the lounge bulkheads which formed the "indentation".This particular fan housing has corroded away on the outboard side, allowing one to see directly into the fan plenum. Looking at the interior configuration of the fan housing, I could see where the air would exhaust downward out the forward half of the housing assembly. No evidence and few thoughts. Without more information on this "indentation" I'm not quite sure what the difficulty is. On both Olympic and Titanic there is a 20 inch cowl sirocco fan which is located on the raised roof over the First class lounge on the port side Sir Samuel Cleland Davidson, KBE (18 November 1846 – 18 August 1921) was a British inventor and engineer. Through his career in the tea import business he invented and patented a number of industrial machines and developed the earliest air conditioning systems. He founded the Sirocco Works in Belfast in 1881. Possibly superstructure framing did not correspond in this case. Outside of the ship girder proper I would think there would be some leeway for the designers.
