Function

The air is supplied into the space through the adjustable nozzles in front panel of the diffuser.

The individual nozzle includes two separate flow channels that enable a large free area for supply air and effective mixing effect. The supply air pattern can be freely directed radially in the direction(s) desired (1, 2, 3 and 4) by rotating the nozzles. Horizontal swirl or compact air patterns can also be achieved by adjusting the nozzles.

Direction of the supply air jet has no effect on the noise level, pressure drop or airflow rate.

The recommended maximum temperature difference between supply and room air is 10 0C.

Installation

  
Fig.1.  Installation above list                        Fig.2. Installation under list
 

The diffuser is available in size 595x595 for direct integration to the modular T-bar ceiling (600x600).

Ceiling installation for standard sizes can be made above or below T-bars.

The diffuser is connected either direct to the duct by screwing or riveting, alternatively to the Halton’s connection plenums TRI or TRH.

Direct the flow pattern in the desired directions by individually rotating each nozzle in order to meet the required specifications (directed at 4 ways as standard).

A recommended minimum safety distance upstream of the diffuser is normally 3 x duct diameter.

Installation with plenum

The collar in Halton’s TRI can be installed either internally or externally on the bottom of plenum. The height of unit is presented in the tab Dimensions.

A recommended minimum safety distance upstream of the plenum is normally 3 x duct diameter.

The technical performance for the combination of Halton Jaz Sky Ceiling diffuser and Halton plenum is presented separately for different installations.

Opening the diffuser

Open the front panel using some suitable thin material (like plastic sheet - Fig.4.). Push the sheet on the slot between front panel and chamber on the side where the Halton logo is located (distance about 50 mm from the corners). Pull slightly to open the front panel.

Detach the open front panel by pressing the hinge from inside (Fig.5); reassembly it by pulling it against the hinges.

Close the front panel by pushing it until the springs lock.

Adjustment

Halton Jaz Sky Ceiling diffuser does not include any separate airflow adjustment.

In order to enable the adjustment and measurement of airflow rate it will be recommended to connect the diffuser to Halton TRI or TRH plenum. The supply airflow rate is determined by using the plenum’s measurement and adjustment module.

Open the diffuser’s front panel and pass the tubes and control spindle through the plastic nozzle. Replace then the front panel.

Measure the differential pressure using a suitable manometer. The airflow rate is calculated using the formula below. 

 

TRI > 8xD min. 3xD
100 6.0 7.5
125 9.9 12.6
160 16.9 21.9
200 28.3 32.0
250 47.9 51.5
315 78.6 -

 

TRH > 8xD min. 3xD
100 6.5 7.5
125 10.8 12.6
160 19.4 21.9
200 29.7 31.0
250 48.8 51.

           

Adjust the airflow rate by rotating the control spindle until the desired setting is achieved. If needed lock the damper position with the screw in module.

Replace the tubes and spindle into the plenum.

Servicing

Detach the front panel of the diffuser and let it balance on the hinges. If needed, each nozzle can be easily removed by pressing the stoppers and then pushing the nozzle through the front panel. Wipe the diffuser casing, nozzles and front panel with damp cloth.

The nozzles are replaced into the front panel by pushing. After cleaning reattach the front panel.
 

Option with balancing plenum  

Remove the measurement and adjustment module by gently pulling from the shaft; not from the control spindle or measurement tubes.

Wipe the components with damp cloth instead of immersing in water. Wipe also the inner part of the plenum; detach the attenuation material if needed.

Reassemble the module by pushing the shaft until the unit meets the stopper.

Push the front panel back into casing so that the springs lock.

Specification

The diffuser is installed flush with the ceiling surface. The diffuser is made of powder painted galvanised steel with a white standard colour (RAL 9010). Air is supplied through the plastic nozzles, which have two-slot design in order to ensure efficient mixing of supply air. Nozzles are also individually adjustable for providing high flexibility for the adjustment of throw pattern.

The diffuser has a detachable front panel providing access to the duct and/or plenum.

The diffuser is installed alternatively to the balancing plenum or direct to the duct. Connection plenum has a detachable measurement and adjustment module, attenuation material and cleanable structure.
