Function
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.
Installation
Fig. 5. Halton TRB diffuser connected to a Halton Pop PDI plenum
The diffuser is connected usually to balancing plenum Halton Pop PDI (see Fig.5.). Alternatively, it can be connected direct to the duct by riveting or screwing. In that case, minimum safety distance to the next T-branch or curve is three times the duct diameter (3xD).
Adjustment
Fig. 6. Adjustment of airflow of diffuser and plenum combination
Airflow control
The diffuser itself has no airflow adjustment. To adjust and measure the supply airflow rate, the diffuser shall be combined with Halton Pop PDI balancing plenum with measurement and adjustment module MSM. In case of exhaust air, use of adjustment module MEM is recommended. It is not possible to measure exhaust airflow rate with adjustment module MEM.
Open the front plate and pass the tubes and control spindle through the front panel (Fig. 6.). Replace the front panel. Measure the differential pressure with a manometer. The flow rate is calculated using the formula below:
where
- qv Airflow rate [l/s] or [m3/h]
- ∆pm Measured pressure [Pa]
- k The k factor (see the table below)
Adjust the airflow rate by rotating the control spindle until the desired airflow rate (pressure difference) is achieved.
Set the tubes and spindle back into the plenum. Damper position can be locked with a knurled head screw of the adjuster.

Servicing
Detach the cone module of the diffuser and clean the parts by wiping with a damp cloth.
Reinstall the cone module.
Specification
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.
