The Halton Max Slim Box includes a closed loop controller, comprising an aluminium differential pressure measuring probe, an actuator mounted on the damper blade spindle and a controller. This system allows the air volume to be accurately regulated independently of variations in upstream pressure. It can be used in a supply or exhaust application. Measurements made by the differential pressure sensor are sent to the controller which compares these values with the required room setpoint value. The controller compares the actual values with the setpoint value and sends a signal to the actuator which adjusts the position of the damper to compensate for the difference.

The controller compares the actual values with the setpoint value and sends a signal to the actuator which adjusts the position of the damper to compensate for the difference. An analogue signal to alter the setpoint value can also be sent to the controller and the flow rate will then be adjusted to the new setpoint. Volume flow rates are regulated between the pre-set min. and max. values in the controller.

The Halton Max Slim Box airflow management unit can be applied in both supply and exhaust Variable Air Volume applications. Its compact, low profile design permits installation into challenging spaces where access is limited or where room and false ceiling heights are restricted. The dynamic pressure measurement system allows an accurate measurement of the airflow without upstream safety distances.
The Halton Max Slim Box comprises:
• an airflow control damper blade
• an aluminium airflow differential pressure measurement probe installed centrally inside the plenum
• an integrated silencer
The pressure differential probe measures the average pressure across the whole surface, and from that accurately determines the actual volume of air passing through the unit. The position of the damper blade is then constantly calculated and adjusted by the actuator mounted on the spindle of the damper blade, in response to the measurements from the dynamic pressure sensor and electronic controller.
The selection of the VAV box is done according to the range of airflow it is designed to control based on performance data compiled from results of performance tests carried out in our Innovation Hubs and Laboratories. Each plenum is calibrated and the controls are pre-set at our factory to the minimum and maximum airflow conditions specified by the client. Factory pre-set parameters and project reference identification information are clearly marked on each unit. The acoustic properties of the Halton Max Slim Box are improved by the inclusion of a symmetrical attenuator containing Euroclass A2 s1 d0 high density mineral wool.
Minimum and maximum airflow values stated are indicative only and can differ by control type or brand, so please check with Halton prior to ordering.
The Dynamic Measuring System within the Halton Max Slim Box allows it to be installed directly after a T, elbow or reduction or even on to a main riser duct without affecting the accuracy of the air volume measurement.
Therefore, there is no requirement for safety distances.
