Function

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

Installation

Key
1.   Plastic plug
2.   Central fixing screw
3.   Halton TSR diffuser
4.   Mounting bracket
5.   Halton TRI plenum

The diffuser is connected either directly to the duct by screwing or riveting, or alternatively to the Halton TRI or TRH balancing plenum.

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

Installation with plenum Halton TRI

The mounting bracket should be used for installing Halton TSR to TRI plenum to allow easy diffuser removal.

The collar of Halton TRI plenum can be installed either internally in the plenum or externally on the bottom of the plenum. The height of the unit for the extern al installation is presented in the table below. When the collar is installed internally, the total height H1 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 TSR itself has no means for airflow adjustment.

In order to enable airflow adjustment and measurement of airflow rate it is recommended to connect the diffuser to the Halton TRI balancing plenum. The supply flow rate is determined by using the measurement and adjustment module MSM.

Detach the diffuser and pass the tubes and control spindle through the blades of the diffuser and replace the diffuser.
Measure the differential pressure with 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 into the plenum.

Servicing

Wipe the diffuser with a damp cloth.

Option with balancing plenum

Detach the diffuser from the retaining mounting bracket. Remove the measurement and adjustment module by gently pulling the shaft (not from 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 unit meets the stopper. Replace the diffuser.

Specification

The diffuser is made of epoxy-painted steel with a white (RAL 9003) standard colour.
The swirl diffuser has fixed spiral blades ensuring a high mixing rate.

Alternative 1: No balancing plenum

The diffuser has a steel casing and front vane panel.

Alternative 2: Option with balancing plenum

The diffuser is connected with a mounting bracket to a balancing plenum equipped with a measurement and adjustment module.
The diffuser is detachable to provide access to the measurement and adjustment module in the plenum.

The balancing plenum has a spigot with integral gasket for airtight duct connection.
The balancing plenum comprises sound attenuation material made of polyester fibre with a washable surface.
