Aggreko wins Eurovision


Aggreko successfully provided the Eurovision Song Contest 2010 with over 9 MW for the three day event. Previously, the annual competition, which this year took place at Oslo’s Telenor Arena, relied on a number of different contractors and this was the first time the organisers relied on a single provider for its power and temperature control needs.


Four Aggreko 1250 kVA generators produced power for lighting, video and rigging. Aggreko provided an additional 4 MW for outside broadcast crews, press


conference facilities, media, catering, sound, cameras, pyrotechnics and management offices. A further 1 MW was used to power the air conditioning, to cool the massive main stage lighting rig, as well as the backstage area.


To counter the heat generated by the lighting rig and ensure the performance of the stunning display, Aggreko installed a system using four 200 kW air handlers, ducted out to the roof. This is the first time such a system has been used to reduce the operating temperature of such a rig.


Pizza Hut slices 85% off costs An 85 percent


reduction in cooker hood electricity costs is being achieved at Pizza Hut’s Watford Dome branch following the installation of a 1.5 kW and a 3 kW ABB drive on the air extraction cooker hood system.


The new system,


installed by Food Industry Technical (FIT), controls air supply and extraction by monitoring carbon dioxide (CO2


) and


temperature in the kitchen. FIT was approached to provide a system that would improve energy efficiency in the kitchen – achieved by matching fan speeds to the needs of the application. For added safety the FIT system accurately measures CO2


levels


within the kitchen space and initiates air extraction when levels increase. A CO alarm was also fitted to further ensure staff safety in the kitchen area. Previously, fans were running for 13 hours a day at full speed and consumed between 35 kWh and 45 kWh per day. After the introduction of FIT’s system, controlled by ABB component drives, the fans now use, on average, below 10 kWh


per day, representing a considerable energy saving and a payback period of just 18 months. This has been achieved by matching the speed of the fans to the demands of the application.


By using a 1.5 kW ABB component drive,


FIT could vary the speed of the extractor fan motor by monitoring CO2


and


temperature and feeding the values back to the drive. Similarly a 3 kW ABB component drive was fitted to the supply fan. The system automatically reacts to CO2


levels and the temperature sensors ramp up the drives to 100 percent if temperature in the kitchen exceeds 34 degrees or CO2


exceeds 2500 ppm.


The system also features a fail safe mechanism to enhance safety – in the event of a control cable being severed, or a sensor failing, the drives will automatically ramp up to 100 percent and stay there until the fault is rectified, ensuring air supply to the kitchens remains at safe levels.

Westway supply critical services


When Anite needed to upgrade their building in Slough to provide a more resilient power service and critical cooling provision in the existing data and comms equipment halls they turned to Westway Services for their help in project management and implementation of the various services.


Anite is an international software and solutions company focused on the provision of test & operational systems in the wireless market and reservation & e- commerce solutions to the leisure travel industry and as such has a 24/7 demand on its business services. In addition market growth is leading to a constant demand for improved systems.


Building & Facilities Management – July 2010


The Anite project was a very fast track program that involved installing a new acoustically enclosed diesel generator set, associated cabling and switchgear to provide additional resilience to over 1.2MW of new cooling systems. Due to the business continuity requirements of Anite coupled with working in a live environment, Westway had to carefully plan, identify and manage any potential risks. This was achieved successfully by utilising the project management experience gained with other similar projects over the years. By careful planning Westway were able to bring forward the anticipated completion dates. www.westwayservices.com


The live final on 29th May was watched by an estimated global audience of 120 million viewers.

New steam-to- steam humidifier


JS Humidifiers is launching the new Neptronic SKS steam-to-steam humidifier. The Neptronic SKS uses an existing energy supply of impure boiler steam or high temperature liquid through a sealed heat exchanger to create sterile steam suitable for air humidification. The Neptronic SKS can provide up to 600kg/hr of steam to an air handling unit or duct from steam, high


temperature hot water or high temperature oil. Using an existing energy supply to create the pure steam is much more energy efficient, and has a lower carbon footprint, than electric steam humidification. It is ideal for buildings such as hospitals, universities, pharmaceutical manufacturing and other large institutions with steam or high temperature liquid circuits. A scale management system within the humidifier helps reduce necessary maintenance. Scale that builds up on the heating elements cracks from the surface when the elements expand and contract during operation. This scale drops to a sloped surface at the bottom of the boiling chamber where the incoming water supply forces it into removable “scale trap trays”. The top of the Neptronic SKS has easy access, insulated panels, enabling the unit to be drained, opened and emptied of scale in minutes.


A patented Anti-Foaming Energy Conservation (AFEC) system accurately determines the presence of foam in the humidifier. Unlike other similar humidifiers, which regularly skim hot water to drain to combat foaming, the Neptronic SKS only drains to prevent foaming when foam is actually present. This saves expensive boiling water and reduces energy use whilst protecting the heating elements from damage due to foaming. Email: sales@jshumidifiers.com www.jshumidifiers.com
