RCS (Room Comfort Support) With the use of RCS, you avoid the risk of getting a draft in the occupied zone and with an unhealthy workplace. To arrange the vanes in a pattern when beams have a risk to collide, are easily done and doesn’t affect pressure drop or noise level. NCS (Nozzle Control System) With the possibility to select a range of nozzle position that suits your installation. You will be able to adjust to the desired supply airow by selecting Nozzle positions L (Low), M (Mid) and H (for higher capacities by combining Low and Mid nozzles). Following possibilities can provide you with...
