Halton TSA with electric actuator

  • Siemens GDB161.2E/HA actuator with 24 VAC power supply and proportional 0…10 VDC control signal
     

Halton TSA with wax-bulb actuator

  • Halton TSA can be equipped with a wax-bulb actuator, which work without any power supply. The cylinder position changes according to the temperature of supply air.
  • The temperature range of the wax-bulb actuator is about 20 °C to 27 °C.
  • The time taken to change from radial to compact jet (or the other way around) is 10 - 20 minutes.
  • When warm air is supplied the piston of the wax bulb actuator keeps moving until the TSA supply air pattern is vertical. When cold air is supplied, the TSA supply air pattern is changed back to horizontal by means of a spring.


Function

Function


Halton TSA



                     Compact jet                                    Radial Jet
 

  • The Halton TSA is a high induction swirl diffuser with an adjustable flow pattern. The horizontal radial swirl jet is used mainly in cooling applications that use cool supply air or for ventilation with isothermal supply air.
     
  • The vertical compact swirl jet with warm supply air is used in heating applications.
     
  • Adjustment of the supply air pattern is effected by moving the internal adjustment element (cylinder).
     
  • It is also possible to change from cooling mode to heating mode by adjusting the flow pattern using an electric or wax bulb actuator.
     
  • The recommended maximum temperature differences between room and supply air temperatures are +15 °C for heating and -15 °C for cooling applications.
     

Installation

Installation


Halton TSA

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

The front vane panel can be reattached

  • Remove the screws through the front vane panel (sizes 250 and 315) or between the cylinder and casing (sizes 400, 500 and 630), turn and hold the front vane panel to remove.

Take care during installation to ensure that the cylinder can move freely and that the actuator has adequate installation space. There should be at least 50 mm clearance space above the top of the device when the cylinder is in the lowest position. The connection and fixing rivets or screws may not be located more than 50 mm below the upper edge of the diffuser.

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

Wiring and DIL switches



DIL switches:

1.  Automatic adaptation of limited movement length to 0-10 VDC control signal
2.  Direction of shaft movement based on 0-10 VDC control signal
3.  Feedback signal

 

Installation with plenum



Ensure that the actuator has adequate installation space when installed in TRI plenum. It is recommended to install the collar outwards.

The dimensions are with the outlet sleeve outside the plenum and diffuser without any actuator.

It is recommended that the distance between the Halton PLC plenum and Halton TSA sizes 500 and 630 is at least 1xD to ensure proper diffuser operation.

Throw pattern adjustment

The supply air jet is adjusted by changing the position of the cylinder.

When you turn the knob clockwise the throw pattern is changes from radial to compact.
 

Airflow adjustment

It is not possible to adjust the airflow in Halton TSA itself.
In order to enable airflow adjustment and measurement of airflow rate it is recommended that you connect the diffuser TSA 250, 315 and 400 to the Halton TRI balancing plenum. The supply flow rate is determined by using the measurement and adjustment module MSM.

Pass the tubes and control spindle through the front vane 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. Replace the tubes and spindle in the plenum.
 

Servicing

Servicing


Halton TSA
 

Remove the front vane panel and clean the diffuser by wiping it with a damp cloth, instead of immersing it in water.
 

Option with balancing plenum

Remove the measurement and adjustment module by pulling gently the shaft; (not the control spindle or measurement tubes!).
Wipe the parts with a damp cloth, instead of immersing them in water.
Remount the measurement and adjustment module by pushing the shaft until the module meets the stopper.
 

Technical specification text

Technical specification text

 

The diffuser shall consist of a frame with fixed internal profiled vane rings and a movable cylinder for throw pattern selection.
The front vane panel, the movable cylinder and the frame shall be made of powder painted steel, with a white (RAL 9010) as standard colour.

The airflow pattern shall be adjustable automatically using an electrical or wax-bulb actuator, (in applications where both heating and cooling are required.)
