T5 gets set for Flakt Woods
Published:  21 December, 2005

Fläkt Woods will be providing fans to ventilate Heathrow’s new Terminal 5 building which will be used to provide general venting solutions, stair pressurisation, roof venting and smoke control at the new terminal.

More than 200 of the company’s JM fans have been ordered by Hotchkiss. A variety of different diameter high temperature fans are being delivered, ranging from 500mm to 1,400mm in width, and capable of withstanding temperatures of 300°C for a maximum of two hours.

Terminal 5 provides an extremely large-scale challenge for building services, with Fläkt Woods having to calculate the requirements for an interior area which could accommodate approximately 50 football pitches. In addition, the fans will need to be extremely efficient and effective at venting within strict acoustic parameters due to the large open spaces and extensive use of glazing to control noise pollution.

As well as providing employees with a safe environment, the provision of good quality air supply is vital for the anticipated 30 million additional passengers that Terminal 5 will cater for.
