Function

The duct pressure and air velocity are reduced inside the Halton BDR plenum box. Consequently supply air is evenly spread over the surface of the grille. The airflow rate can be adjusted using the optional measurement and adjustment module MSM.

Installation

The Halton BDR plenum is connected to the distribution ductwork with a spigot.
When equipped with a measurement and adjustment module (1), the recommended safety distance upstream of the device is at least 3xD, in order to ensure a reliable airflow rate measurement.

The unit's control spindle must not be excessively bent.

With wall installations the required hole size is at least (L x H).

The spigot comprises two grooves to enable the grille springs to lock.
 

Clip Fastening of grille  (Standard)

Adjustment

In order to enable airflow adjustment and measurement of airflow rate, it is recommended that the grille be connected to the plenum equipped with the MSM module.
The supply flow rate is determined by using the measurement and adjustment module MSM.

Detach the grille and pass the tubes and control spindle through the grille.
Push the grille back into place.
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 and replace the grille.

Exhaust

The airflow rate is determined by measuring the differential pressure between the measurement tap on the Halton BDR plenum and the room air.
The corresponding airflow rate is calculated using the formula above.
The desired airflow rate can be adjusted by turning the control spindle of the adjustment unit MEM.

Servicing

Remove the measurement and adjustment module by gently pulling the shaft (not the control spindle).

Wipe the parts with a damp cloth, instead of immersing in water.

Reassemble the measurement and adjustment module by pushing the shaft back into place until the module meets the stopper.

Specification

The  plenum is made of galvanised steel.

The plenum will comprise an airflow measurement and adjustment unit.
The grille is detachable to provide access to the measurement and adjustment module in the plenum.

The plenum has mineral wool as sound insulation material.

The plenum will reduce duct pressure and air velocity in order to supply air through the whole face area of the grille and improve the air distribution quality.
