Socomec UPS and Sudlows are keeping Metrolink on track Socomec UPS has been selected by Metrolink RATP Dev Ltd (MRDL) to manage the introduction of its latest uninterruptible power supply (UPS) technology in a major upgrade to the Greater Manchester Metrolink light railway critical power infrastructure. Metrolink is currently undergoing a £1.4 billion expansion, and to bring the existing infrastructure in line with the technology required as part of the network’s ambitious expansion programme, Socomec has been tasked with replacing and


reconfiguring nearly 30 UPS systems and battery strings within Stop Equipment Rooms serving key rail lines – one of the most significant developments in the network’s history. From design and build through to installation and


commissioning – as well as ongoing maintenance – Socomec has a strong track record in delivering high profile, complex critical power solutions for the exacting requirements of the rail sector. Sudlows’ power upgrade, combined with next


generation Socomec UPS technology, will provide a resilient electrical infrastructure for the Metrolink network’s growing operational requirements. n www.socomec.com


Twin165 solves desk-to-window height challenge at academy Restricted desk-to-window height throughout a new £17million academy proved a challenge for the project’s M&E contractor – until Marshall-Tufflex’s Twin165 double compartment trunking system was found to be a perfect solution for the scheme. The new North Shore Academy, Stockton, opened its


Dimplex Quantum performance recognised by SAP The improved performance of Dimplex Quantum compared to conventional manual or automatic storage heaters could save homeowners up to £278.21 per year, according to the latest updates to the Standard Assessment Procedure (SAP). SAP, which is the government’s recommended system


for measuring the energy performance of residential dwellings, officially states that the Quantum space heater has greater responsiveness than a conventional manual or automatic storage heater. The responsiveness of a system reflects the ability of


the heater to match the heating needs of a home – a rating defined by the Building Research Establishment (BRE) and documented within SAP. Quantum’s responsiveness rating is 0.8 – compared to manual and automatic storage heaters which are rated at 0.2. This means the improved efficiency of Quantum, which gives users the chance to use stored heat as and when they need it with easy-to-use controls, is changing the peak/off-peak split of energy usage in storage heating. n Call 0844 879 3587 or visit www.dimplex.co.uk/quantum


Integration of remote I/O into BMS installation made easy Carlo Gavazzi has launched the SBWEB BACnet Gateway, which links all field level devices, simplifies wiring and reduces the cost of building automation systems at the device level, while providing BACnet interface capability. Integration of a Dupline network into the BMS environment is easily implemented. Now installers can save money on installation costs by utilising the versatile Dupline two-wire bus network, with simple I/O devices, many of which are powered by the bus itself. All these points can then be discovered by the BMS controller using BACnet. Applications for Dupline are generally where the I/O


points are distributed over a wide area and are of low density. HVAC, underfloor heating, natural ventilation and alarm point monitoring are good examples, but there are also opportunities for reducing costs within lighting control and energy monitoring and control. The SB2WEB can manage up to seven Dupline


networks, each managing more than 400 data points, and includes a RS485 port for communicating with energy meters. n www.carlogavazzi.co.uk


TLC and profitability go hand in hand with Evo 7 With its new EVO 7 cable tie application tool, global cable management specialist HellermannTyton has given a whole new meaning to ‘TLC’. Ground-breaking tension/lock/cut (TLC) technology means that, in line with four other new products, HellermannTyton has totally re-designed its applicator not only to maximise product benefits, but also to further reduce risk of operator injury. ‘Quite simply,


the innovative


lightweight EVO 7 tool enables installers to increase productivity when applying a wide range of cable ties – in countless installations – while simultaneously reducing the risk of repetitive strain injury,’ said manufacturing product manager Richard Rands. Designed to be the slickest modern application tool on the market, the EVO 7 has a soft, non-slip handle with a built-in air cushion to reduce pressure points in the operator’s hand, while the soft-touch trigger features individual finger grips for fast and efficient use. Recoil or interfering vibration are also eliminated during cutting, plus the tool is available in two ‘hand’ sizes (the 7 and 7SP) for ultimate comfort. n www.hellermanntyton.com


doors to 1,000 pupils in May 2013. The academy required high levels of power and data supplies to be delivered to numerous outlets throughout the building, with space for cable management provision at a premium. Mechanical and electrical contractor Shepherd Engineering Services (SES) ruled out three compartment trunking simply because the desk-to- window height throughout the building was insufficient to accommodate these larger solutions. Twin165 allowed the most space, permitting approximately 50mm above the desks and 15mm below the window sills, whereas other double compartment dado trunking allowed only 5 or 6mm. Approximately 1,500m of the robust CAT 6 compliant, PVC-U trunking has been installed within virtually every classroom and open plan teaching area of the academy. n Email marketing@marshall-tufflex.com or visit www.marshall-tufflex.com


GE Lighting shines new light on the streets of Bristol GE Lighting has upgraded the street lighting in Bristol to deliver an energy efficient, white light solution – part of Bristol City Council’s aim to reduce its carbon footprint and to promote a safer urban environment. The project comprises the replacement of existing high-pressure sodium street lighting with GE’s improved, higher efficiency CMH Streetwise ceramic metal halide lamps. Much closer to daylight, white light also offers further


advantages in that pedestrians feel more secure in their environment, and car-driver reaction time (mescopic vision) is reportedly at least six times quicker. Bristol Council has rolled-out the street lighting


upgrade in two phases, the first of which saw the replacement of around 8,000 existing high pressure sodium lamps to GE’s CMH StreetWise ceramic metal halide lamps. Phase two of the upgrade began in July 2012, and over the course of the next 12 to 18 months will see the replacement of a further 12,000 lamps in Bristol’s residential areas. n www.gelighting.com
