Function

Horizontal radial swirl jet air is supplied into the space through the profiled spiral blades of the diffuser. Supply air jet velocity is effectively reduced due to the high mixing effect.

Halton TSB can also be used as an exhaust unit.

Installation

Code Description
1.  Front panel
2.  Casing

The Halton TSB diffuser is connected either directly to the duct by screwing or by riveting or alternatively to the Halton TRI balancing plenum.
Detach the front panel by pulling it gently down and let it hang by its hinges.
Direct the flow pattern in the desired directions by installing deflector panel on the perforated front panel.
Reattach the front panel by swinging up and pushing until the springs lock.

The recommended minimum safety distance upstream of the diffuser is 3xD.

Installation with plenum

The collar of the Halton TRI plenum can be installed either internally in the plenum or externally onto the bottom of the plenum. The height of the unit is presented in the table below for the external installation. When the collar sleeve is installed internally, the total height H 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.

Adjustment

The Halton TSB 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.

The supply flow rate is determined by using the MSM measurement and adjustment module.
Open the front panel and pass the tubes and control spindle through the diffuser front panel. Replace the front panel.
Measure the differential pressure using a manometer. The flow 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.
Replace the tubes and spindle in the plenum and replace the diffuser front panel.

Servicing

Detach the front panel of the diffuser by gently pulling it down and let it hang by its hinges.
Wipe the parts with a damp cloth.
Push the front panel back into place so that the springs lock.

Option with balancing plenum

Remove the measurement and adjustment module by gently pulling out the shaft (NB. not the control spindle or measurement tubes!).
Wipe the parts with a damp cloth instead of immersing in water.
Remount the measurement and adjustment module by pushing in the shaft until the module meets the stopper.
Push the front panel back into place so that the springs lock.
