The CPJ type diffusers are designed for high ceiling applications. They can be used for supply air, with their superior vertical penetration characteristics for warm air. They also provide an effective swirl throw for cooling.
Specifications
These diffusers have adjustable blades. The blades are adjusted to vertical throw for heating, and to horizontal for cooling. If a proportional servomotor is used, it is possible to have continuous adjustments between vertical and horizontal. These diffusers are mostly good for applications in industrial or commercial buildings. If the diffuser face is installed more than 300 mm below the ceiling, then Coanda effect does not take place and it is possible to have continuous throw angle adjustments between the vertical and the horizontal. However, if the diffuser face is close to the ceiling, then only a vertical or a horizontal throw setting is possible. In cases where the diffuser is apart from the ceiling, and a longer horizontal throw is desired; then a compensator plate is introduced around the diffuser face for some limited horizontal throw enhancement. These diffusers are recommended for use with a supply air temperature difference of (+/-) 10ºC.
