Ventilation contracts are a breath of fresh air for Elta Fans
11 April 2011
The Kingswinford-based manufacturer is supplying a variety of fans to large construction projects in Scotland and the Irish republic
The largest NHS construction project ever undertaken in Scotland - a new acute hospital for NHS Forth Valley - is currently under construction in Larbert, some five miles north west of Falkirk. The first phase is now complete and the hospital opened its doors to patients in August 2010. When it is fully completed, this £300m new-build facility will be one of the most modern and well equipped hospitals in Europe.
Specialist ventilation equipment supplied by Elta Fans was mostly drawn from its ‘Select’ range, which the company claims is one of the widest available directly from stock. The order included two Powerduct SPD fans, a Multiflow SMB, six SmokeVent LCS fans, a Quietflow Twin, and two JetFlow fans. Some twenty plastic cased centrifugal fans, which could not be supplied from Elta’s all-metal portfolio, were obtained under the terms of a special collaboration from Glasgow based national ventilation systems distributor, Fans & Spares.
Powerduct SPD is a robust, duct-mounted, square-cased, in-line centrifugal fan that delivers high performance and low noise, while Multiflow SMB are square-cased, mixed-flow fans equipped with adjustable-pitch, mixed-flow impellers, for installation within ducts. SmokeVent is for general ventilation plus emergency smoke extract and Quietflow SQT is an acoustically treated, in-line, centrifugal twin-fan range, intended for internal mounting in buildings with low ceiling voids, where the fans are located close to the building’s occupants. Jetflow, which is the name Elta gives to its range of all-metal in-line centrifugal fans, describes an extensive line of high performance units that can be used in either extract or supply applications.
Meanwhile, across the water, Dublin based Fantech Ventilation has just supplied its largest ever order for car park ventilation equipment for a turnkey project at a new Tesco superstore in Portlaoise, Ireland, supplying a wide range of fans, grilles, diffusers, air handling and heat recovery products manufactured by Elta Fans.
Elta’s JetVent was specifically developed for car parks, providing a simple, reliable means of removing pollutants in smoke-spill situations and for rapid, emergency clearance of fire, smoke or hazardous fumes. These low-profile, centrifugal fans are generally used in ‘impulse ventilation’ systems, where they provide a high-velocity airflow to overcome problems caused by the structural beams and low ceilings that are typical of enclosed car parks.
Impulse ventilation involves a number of small, strategically located fans in place of the distribution ductwork traditionally used in car parks, each producing a high velocity jet, which directs airflow towards the main extract fans. The latter are typically smaller than would otherwise be the case, as they don’t have to cope with the adverse effects of ducts.
