dnp screens give clear view of process control

Our installation of the month is the process control centre at waste management company, Vestforbrænding (Copenhagen, Denmark). Given that Vestforbrænding strives to minimise waste and pollution for customers, its selection of display media was also strongly guided by environmental considerations.

Clear view of processes is vital

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. 

Strong environmental philosophy

When the time came to equip its process surveillance centre, Vestforbrænding demanded more than the unobstructed visual clarity of a rear projection system. The solution also had to be compatible with its strong environmental philosophy. The exisiting system was based on lamps, “We recommended DLP rear projection cubes for Vestforbrænding,” says 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.”

Bright, sharp images

Vestforbrænding’s dnp installation is a curved wall (8°) with twelve dnp 50“ EC-50-LSXT+ screens in a 6 x 2 array. The cubes have a resolution of 1400 x 1050 pixels.

The dnp Cross Prism screens making up the wall 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,” says Eric Hénique, Director Marketing and International Sales at eyevis. “When the operators saw the final result and compared the new system with the old system they had, they were overwhelmed by the superior image quality” states Johan Smidebrant.
