Elta’s Breath Of Fresh Air For New Overground Station

Elta has supplied four 1250mm, long-case (LC), ‘Run and Standby’ fans for the new Dalston Junction Railway Station, currently under construction in the London Borough of Hackney – as part of a fresh-air input system.

The LC Range is an extensive selection of robust, long-cased axial fans, fitted with adjustable-pitch, aerofoil-section, bladed impellers and offers performance with strength, durability and corrosion resistance.

The fans were produced in a collaborative project between the Fareham and Kingswinford manufacturing facilities of fan specialist Elta, for the pressurised ventilation system at the new station. Supplied and fitted by Elta’s Building Services division customer Advanced Smoke Technology Limited, experts in the design and installation of smoke control, extract and pressurisation systems, the units are mounted in pairs on purpose-built frames on the ceiling of the station building above the west and east stairwells. They are wired into the master control panel of a pressurisation system, which incorporates an automatic changeover facility should the duty fan fail to switch to ‘standby’ mode. In this way, constant ventilation and a positive pressure are maintained within the stairwells of the station.

Advanced Smoke’s spokesman, Brian Lockton commented: “We have had a good working relationship with Elta for some time now. This job involved various exacting stipulations because of the sensitivity of fire hazard in stations. We have always found that by working closely with them, we are able to overcome any technical difficulties with comparative ease.”

Finished in RAL 7001 matt grey to the specification of the customer (London Underground Limited – LUL), the units and accessories supplied meet the requirements of Section 2 Materials Approval as defined in the Fire Precautions Act and LUL Standard Fire Safety Performance of Materials Specification. The LUL requirement is associated with the paint finish of the units, which is specially formulated for areas requiring low smoke and low, toxic-fume emission. It is also graffiti resistant.

Specialised, electrical cabling within the fans from the motors to the external terminal boxes also complied with Section 12 of the LUL Specification – being heavy duty, enhanced oil-resisting, flame retardant with low smoke and zero halogen-gas emissions.

Main contractor for the Dalston Junction Railway Station project is Mansells Construction with engineering services supplied by Briggs & Forrester.

Although the original station closed over two decades ago on 27 June 1986, along with the railway line it served, the neighbourhood retains its name, with road signs and bus stops alike still referring to the area as ‘Dalston Junction’.

Located at the corner of Kingsland High Street and Dalston Lane, the station first opened on 1 November 1865 as part of an extension to Broad Street on the North London Line. Remains of the former station were cleared in early 2005 and the station is on schedule to re-open in May 2010 – initially as the temporary northern terminus on the Chelsea-Hackney Line route between Wimbledon and Epping, as part of the London Overground East London Line extension.

The new station is 250 metres from an existing station, Dalston Kingsland, but future railway maps will show the two stations as a single interchange.
