Increasing numbers of customers are looking at the green credentials of the AV solutions proposed to them – but when the customer concerned is in the waste management business, it’s no surprise that those credentials come under even closer scrutiny.
That was the case with Danish waste management company Vestforbrænding, who needed a solution for the company’s process control centre. The outcome of their investigation was the installation by eyevis and Swedish integrator Viju of a 6 x 2 array of 50” DLP rear-projection cubes featuring LED projection technology, SXGA+ resolution and Cross Prism screens from dnp denmark.
Vestforbrænding processes around 900,000 tonnes of waste a year, 95% of which is recycled or used in energy recovery. 300 employees meet the needs of around 865,000 people – one sixth of Denmark’s population – and 60,000 businesses. All this demands a large facility, including six recycling centres. Vestforbrænding also operates Denmark’s largest incineration plant, which provides both power and district heating. Naturally, all the company’s processes involved must be monitored and controlled meticulously.
When the time came to equip its process surveillance centre, Vestforbrænding demanded that the proposed solution had to be compatible with its strong environmental philosophy. The existing system was based on lamps. “We recommended DLP rear projection cubes for Vestforbrænding,” said Johan Smidebrant, sales manager at Viju Sweden, a Scandinavian partner of eyevis. “With fewer wearing parts, the LED light source has a much longer service life compared with lamp-based cubes, which is a real environmental advantage.”
Vestforbrænding’s dnp installation is a curved wall (8°) with 12 dnp 50“ EC-50-LSXT+ screens in a 6 x 2 array. The cubes have a resolution of 1,400 x 1,050 pixels.
The dnp Cross Prism screens making up the wall are said to offer high dimensional stability, enabling almost invisible seams, as well as eliminating speckle. “dnp’s Cross Prism screens give Vestforbrænding bright, clean images, even close up, with high contrast and the wide viewing angle needed in a control centre,” according to Eric Hénique, director of marketing and international sales at eyevis.
