Functional description
The control damper blade works as an actuator and as an effective pressure sensor. The differential pressure is measured via the hollow damper blade and the signal is passed through channels in the shaft where it reaches the transducer (static or dynamic), it is then converted into an electrical signal and compared with the setpoint value.
In the case of a control deviation, the integrated actuator changes the position of the control damper blade. As a result, the volume flow rate is maintained at a constant level in close tolerances over the entire differential pressure range.
Due to the above measurement and control principles, to ensure stability and accuracy throughout product lifecycle, we advise that controllers with static transducers are used on all extract applications (i.e. XS0).
Nominal sizes | 100 – 400 mm |
---|---|
Volume flow rate range | 4 - 1388 l/s or 14 - 5000 m³/h |
Volume flow rate control range (unit with dynamic effective pressure measurement) | Approx. 4 – 100 % of the nominal volume flow rate |
Minimum differential pressure | Up to 50 Pa (without circular silencer) |
Maximum differential pressure | Control component with dynamic transducer: 900 Pa, control component with static transducer: 600 Pa |
Operating temperature | 10 to 50 °C |
Quick sizing tables provide a good overview of the minimum differential pressures, the volume flow rate accuracy and the room sound pressure levels that can be expected. Intermediate values may be achieved by interpolation. The sound power levels for calculating the sound pressure levels were measured in the TROX laboratory according to DIN EN ISO 5135 - see "Basic information and nomenclature". Precise results and spectral data for all control components can be calculated with our Easy Product Finder design program. The first selection criteria for the nominal size are the actual volume flow rates qvmin and qvmax.
Volume flow rate ranges and minimum differential pressure values
The minimum differential pressure of VAV terminal units is an important factor in designing the ductwork and in rating the fan including speed control. Sufficient static differential pressure (Δpstat,min) must be ensured for all operating conditions and for all controllers. The measurement points for fan speed control must be selected accordingly. The volume flow rates given for VAV terminal units depend on the nominal size and on the control component (attachment) that is installed.

Quick sizing table for sound pressure levels
The quick sizing tables are based on generally accepted attenuation levels. If the sound pressure level exceeds the required level, a larger air terminal unit and/or a silencer or acoustic cladding is required. For more information on the acoustic data, see basic information and nomenclature.

Upstream conditions
The effective pressure, which is decisive for the volume flow rate, is recorded and averaged on the control damper blade. Therefore, the volume flow rate accuracy Δqv is independent of the upstream section.
Duct connections, e.g. branches off the main duct, must comply with EN 1506 and EN 13180.
