Flakt Woods – Fans Of Westfield Shopping Centre
Restrictions in site access meant a helicopter was used by Fläkt Woods as an aerial crane to carry some of their car park jet fans on-site as part of a gigantic three contract fan package for the recently opened Westfield Stratford City shopping centre in East London.
Westfield Stratford City is the largest urban shopping centre in Europe. The 1.9 million sq ft retail and leisure destination is located at the gateway to the site of the 2012 London Olympics.
Working in partnership with E&S on the car park contract, Fläkt Woods engineers installed 150 of their jet fans. These have been prefabricated off-site and come complete as plug and play units with controls and a strict noise deadening acoustic design.
They are supplied as a skid mounted units, saving time on site installation and allowing for testing before installation. To ensure that smoke doesn’t breakout from the skid assemblies all fans are contained within fire rated enclosures manufactured by E&S using their advantaged flame shield ducting which is also included throughout the car park.
Providing ventilation for both day-to-day pollution and emergency smoke, the fans use a CO and LPG sensor monitoring system, so that selected fans only run when necessary. Additional savings are gained because the main extract fans do not need to be oversized to cope with the system resistances found in ducted systems.
Fläkt Woods’s engineers calculated that installation time was halved thanks to the fans pre-fabricated construction, the equipment was packed into a minimum footprint and all components are accessible from the front for ease of servicing.
Under a separate contract on the project, working for FCS Ductwork, Fläkt Woods supplied smoke extract fans for the shops and mall areas. A range of the Company’s bifurcated JM high temperature fans were installed, as these are ideally suited for exhausting hot air up to temperatures of 600°C. All fans have non overloading characteristics.
A third contract at Westfield Stratford City was awarded to the Company to supply and install smoke extraction and ventilation fans plus controls for the walkways throughout the Centre. These fans were part of a package of products supplied for Waagner-Biro.
