The CZC type nozzles are designed for wall and ceiling applications. They can be used for supply air in heating and cooling.
The nozzles are used for throwing conditioned air to long distances. The throw characteristics are suitable for constant or variable air flow rates. The nozzles are a good alternative where normal diffusers or grilles are not preferred. The nozzles can rotate (+/-) 30º about their axis to any direction. However, if an actuator is used, then the rotating motion takes place in a plane (e.g. only up and down). If installed on a wall, the nozzles are turned up for cooling and down for heating.
