CHILLING OUT AT THE SOCHI OLYMPICS I


n order to ensure that the recent Winter Olympics in Sochi, Russia, ran as smoothly as possible, keeping the


relevant competition areas adequately snow covered for the entire event duration was critical. Sufficient natural snow could not be guaranteed, so it


had to be complemented on demand by snow from an alternative, man-made source. Eight of WEG’s 22kW motors formed a crucial part of


the solution. They were located within a pair of large Evapco AT Cooling Towers assembled beside a centrally located pumping station. The feed pipes radiated from the building to competition areas requiring snow cover, where they terminated in tubing areas which were the supply points for mobile snow cannons. In this application the cooling towers were not running 24/7, but they had to respond quickly on demand. They generated chilled water which, after supplemental conditioning, was supplied to the snow cannon. When this conditioned water left the cannon in a sufficiently cold atmosphere, it turned to snow. The two Evapco AT Cooling Towers used were induced


draft axial fan counterflow cooling types. Their design combined low energy consuming axial fans with high performance counterflow heat exchange. Each Sochi unit had four axial fans, each driven by a WEG 22kW motor.


The Institution of Engineering and Technology (IET) has published a new Code of Practice for the Application of LED Lighting Systems. Ben Papé, chair of the IET Technical


The cooling towers had to be resistant to extremes of


temperature and aggressive corrosion. Those at Sochi had to be subjected to standby temperatures of -20˚C. Conditions within the towers were even more challenging with temperature extremes and relative humidity levels of 100% exacerbating the corrosive environment. In the AT range, long lasting corrosion protection was guaranteed with heavy gauge mill hot- dip galvanized steel zinc casing. The galvanized steel construction withstands the most difficult environmental and operating conditions. www.weg.net/uk


Sensors & Instrumentation exhibition expands!


Datateam Business Media, organiser of the annual Sensors & Instrumentation show, has to announce that the 2014 exhibition will be the largest so far. Although there are still seven


months to go before the event takes place, enquiries are up and stand sales are already much higher than this time last year. Kathryn Ambrose, show


organiser, commented, “Due to unprecedented demand, the Sensors & Instrumentation show has expanded! As a direct result of the success of the 2013 event, we have seen the demand for sales outstrip supply, and have therefore increased the floor space to accommodate more stands. “This year we have seen previous


exhibitors rebook with larger stands. In addition, a number of new companies will be exhibiting, having visited during the 2013


event and been so impressed with the quality and quantity of both visitors and exhibitors.” Sensors & Instrumentation 2014


will be co-located with Machine Building, Micro Nano MEMS, and TCT Live, with Interplas and PPMA taking place at the same time - thus increasing footfall still further. The exhibition will be taking place at the NEC, Birmingham, on 30th September and 1st October 2014. sensorsandinstrumentation.co.uk


Committee on LED Lighting Systems, said, “LED lighting is becoming more commonplace and therefore better understanding is needed, alongside the introduction of minimum standards for good installation practice. A Code of Practice will benefit the industry and also build confidence in this technology for contractors and customers.” www.theiet.org


ABB has officially inaugurated its fifth factory in Brazil. The new plant is part of a $200m investment to expand ABB’s technology development and production capacity to serve increasing domestic demand from industries such as petrochemicals, pulp and paper, oil and gas, and mining, as well as energy. www.abb.com


With an estimated 1,950 additional electricians, installers or contractors needed each year between 2014 and 2018, the Electrical Contractors’ Association (ECA) has claimed that the industry needs incentives via public procurement to drive training. Diane Johnson, ECA skills


ambassador said, “The responsibility and cost of training apprentices currently falls largely on SMEs in the electrical contracting sector who need help to secure the future of an industry where the average age is 45. Tying skills and training requirements to public sector contracts will encourage the industry as a whole to invest in apprenticeships.” www.eca.co.uk
