Compact Jet Radial Jet
Halton TRB is a conical ceiling diffuser with an adjustable flow pattern.
The horisontal radial jet is used mainly in cooling applications and the vertical compact jet with warm supply air in heating applications.
The supply air pattern is adjusted by rotating the cone module into the desired position.
The recommended maximum temperature difference between supply air and room air in cooling applications is 10 °C.
Code description
1. Cone module
2. Frame
The Halton TRB diffuser is connected either directly to duct by screwing or by riveting, or alternatively to the Halton TRI balancing plenum.
The minimum recommended safety distance upstream of the diffuser is 3xD.
The collar of Halton TRI plenum can be installed either internally in the plenum or externally onto the bottom of the plenum. The height of the unit for the external installation is presented in the table below. When the collar is installed internally, the total height H2 is reduced by 60 mm.
Note: The technical performance for the combination of supply air diffuser and plenum is presented separately for the two different installations.

The technical performance has been defined for radial jet with cone module opening = 0 mm or for compact jet with opening = -15 mm.
The Halton TRB itself has no means for airflow adjustment.
In order to enable airflow adjustment and measurement of airflow rate it is recommended that the diffuser be connected to the Halton TRI balancing plenum ofr Halton TRH plenum box.
The supply flow rate is determined by using the measurement and adjustment module MSM.
Detach the front panel or the whole diffuser and pass the tubes and control spindle through the cone module of the diffuser.
Replace the cone module or diffuser.
Measure the differential pressure using a manometer. The airflow rate is calculated using the formula below.
Adjust the airflow rate by rotating the control spindle until the desired setting is achieved.
Lock the damper position with a screw.
Reassemble the tubes and spindle into the plenum.

Detach the cone module of the diffuser and clean the parts by wiping with a damp cloth.
Reinstall the cone module.
The ceiling diffuser has a steel (or aluminium) casing with an adjustable cone module and a spigot with integral gasket for connection to the circular duct.
The throw pattern of the diffuser is adjustable in radial or compact jet.
