This visualisation system is just perfect for museum exhibitions. Films or slide shows providing valuable additional information for visitors are shown on displays. For the displays to be able to be used by all visitors, their height has to be able to be adjusted easily and reliably. The design engineers decided in favour of a drylin® W guide system from igus®. In addition to the smooth display movement, the advantage of this system is that it requires absolutely no lubrication, which means exhibits can never become soiled by lubricating greases or oils.
