For one of our customers we have developed a new theatre room inlet plenum. The plenum is made from the highest quality stainless steel and is completely leak-proof because of our unique welding technique. By applying H14 metal plate type filters this system is exceptionally good to validate (integrity test). Because of the good air segregation and the applied air distribution membrane there is a very high laminar air distribution under the plenum. Led lighting is applied in the plenum, which leads to considerably lower energy costs compared to old-fashioned fluorescent lighting. The distribution membrane will not age with the usage of led lighting because there is no release of infra red or UV light. Besides this the lifespan of led lighting is 70.000 hours, which makes it extremely low-maintenance.
