Cooling effects for Cirrus 120 - 300 Chilled Beam Pressure Drop (kPa) and water ow at 0,05 l/s Cooling capacity Water (W) at Tmean Unit size • Cirrus chilled beam for ushmounting in false ceilings • Adapted for standard 600 mm false ceilings module • Available with the following functions: heating, comfort, control, NCS (Nozzle Control System), RCS (Room Comfort Support). Nozzle setting Cirrus 120 - 300 Cirrus is chilled beam and integrates ventilation, cooling and heating. It covers a wide range of supply air and assures you the best room comfort. It is supported with a nozzle technology NCS (nozzle control system) that gives you the highest induction rate and exible air pattern. Together with RCS (room comfort support), it helps you to have a good indoor condition by directing the air so it will create low air velocities in the occupied zone. Cirrus is available in length of 120, 180, 240 and 300 mm and adapted to false ceilings with a module of 600 mm.

Discription and product code Front spigot 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. E 1/2” Pipe male connection NCS (Nozzle Control System) Air-flow direction 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 S (Small), M (Mid) and L (for higher capacities by combining small...
