The Halton BOX airflow management unit is used for airflow adjustment in variable air volume installations, in supply as well as exhaust.

It is composed of:

• a circular inlet spigot equipped with an aluminium airflow measurement probe,
• a damper blade
• a rectangular part equipped with a sound attenuator, allowing air expansion.

The airflow measurement probe measures the average differential pressure across the whole surface of the inlet spigot, thus it allows the correct measurement of the airflow crossing the unit.

The damper actuator is made of two blades with a kinematic link, it enables the reduction of airborne noise as soon as the air enters the unit.

When closed, the damper is air tight.

The main blade is equipped with a gasket to reduce the friction and thus the needed torque of the actuator. The electric power consumption of the regulation loop is also reduced.

The Halton BOX casing airtightness is optimised by a construction with with limited cuttings. The acoustic part of the unit shall be equipped with an asymmetric sound attenuator, enabling an additionnal acoustic attenuation, particularly in the low frequency-range.

The Halton BOX selection is carried out according to its airflow range.

The minimum and maximum airflow values are indicative and can differ by control type or brand.
The Halton BOX is delivered factory-set according to the customer demand.
Factory parameters values as well as identification of the unit in the installation are marked on each unit.

This inside facing consitutes a smooth and washable surface thus limits the microbial development. Thus the unit can be used in areas such as hospitals, laboratories, electronic industries,...
The unit is made of galvanised steel and measurement probes of aluminium.

The unit sound attenuation is made of Euroclass A2 s1 d0 high density mineral wool with coating to avoid tearing, even at high velocities. The insulating material is also inert to bacterial development and can be used in demanding spaces such as hospitals, laboratories, electronic environment… .

The unit can be equipped with a 40 mm thick insulation to reduce radiated noise emission.

For supply application, the unit can be equipped with a hot water reheater or an electric reheater.
