OKNI X

The “OKNI extravent” chilled beam is an adjustable beam fitted with extra nozzles.  These extra nozzles can be activated in groups providing the flexibility to change from small to large nozzles. The adjustment can be done from the front of the beam by sliding a magnetic strip.  This patented system guarantees a 100% air tightness and prevents undesirable sound production. By using the extravents the primary air duty can be significantly adjusted without the requirement to change the installed product to one of a different size. This provides the possibility to alter the application of the beam to suit varying application requirements, i.e. additional air, heating and or cooling.

The “OKNI extravent” chilled beam is a high capacity device designed for ventilation, cooling and heating of areas with ceiling heights up to 3 meters.

The beam has been designed for integration with suspended ceilings with 300,450 or 600mm centers.  Integration in a sheet metal cassette ceiling is also possible.  Due to its lightweight construction it is possible to mount the type 300 in a Tee-bar ceiling or to suspend each beam on drop rods or wires.  We suggest type 600 to be suspended on drop rods or wires.
The closed beam supplies air from both sides and due to its high induction rate can be mounted parallel to the perimeter in the middle of an office. In order to obtain an efficient combination of ventilation and cooling capacity, three different nozzle types are available.  
To facilitate nozzle and coil cleaning, the perforated face-plate is removable without the need of tools. (page 464)
