Function

The Halton UKV is a variable air volume control damper for ventilation systems. The damper can function electrically, with maximum and minimum set values for volume flow rate, factory preset. The damper can also be used as constant air volume control damper. The damper maintains an airflow rate in a duct branch in accordance with the set value independent of duct upstream pressure variation. The set value can be achieved by room temperature controller with output (0...10VDC or 2...10VDC) which will reset the airflow rate for the required value.

Variation of upstream pressure will affect the measurement system; it will notice a difference between the set point and measured value. Volume controller will send a signal to the actuator to recover the set value.

The dampers can be connected to a building management system, whereupon they can be remotely controlled. In such a case, the volume flow rates in different spaces of the building can also be monitored.

The Halton UKV meets the requirements of EN 1751 tightness class 1  


Models E6 and E7 operates as fast running actuators and do not include airflow controller. Use the Halton Laboset for airflow control.

The UKV airflow control damper is available in several versions 

  Model   Feature
  UKV, MD=N    No external frame insulation
  UKV, MD=I1   with 15 mm external insulation 
  UKV, MD=I2   with 30 mm external insulation

 

Control units (CU)

The UKV airflow control damper can be equipped with several different control units for either airflow or duct pressure control.

Airflow controller options:
        EM      Halton LMV-D3-MF-F.1 HI (5 Nm)
        EK      Halton NMV-D3-MF-F.1 HI (10 Nm)
        EC      Halton LMV-D3-MP-F.1 HI (5 Nm)
        EE      Halton NMV-D3-MP-F.1 HI (10 Nm)
        ED      Belimo VRD3 + NM24A-V (10 Nm)
        EG      Siemens GLB181.1E/3 (10 Nm)

Controllers EM, EK, EC, EE and ED include a dynamic differential pressure sensor with a low bypass airflow rate through the sensor element. Therefore, these controllers are not to be used in highly contaminated environments. The pressure sensor of the EG unit is based on a membrane with no flow through the sensor element. Controllers EC and EE include Belimo's MP-bus connection.

Controller ED includes two potentiometers for minimum and maximum airflow setpoint adjustment (ranges: minimum = 0…80% and maximum = 30…100%).

The adjustable airflow control range is presented in the table below. For airflow controllers EM, EK, EC, EE and EG, the highest available minimum airflow rate equals the specified maximum airflow rate.
Minimum and maximum airflow rates are calculated as percentage of damper's nominal airflow.

For the ED controller, the highest minimum airflow rate is 80% of the specified maximum airflow rate.
Maximum airflow is calculated as percentage of nominal airflow and minimum airflow as percentage of maximum airflow.

Pressure control

  • For supply and exhaust installations
  • Static pressure setpoint range of 30...100 Pa or 90...300 Pa
  • Operating range: ambient temperature of 0 to 50 ºC
  • Ambient relative humidity < 95%, non-condensing
     

Static pressure controller options:
       
ES      Belimo VRP-STP+ VFP-100 + NM24A-V
                   (10 Nm, setpoint range: 30...100 Pa)
        ER      Belimo VRP-STP + VFP-300 + NM24A-V
                   (10 Nm, setpoint range: 90...300 Pa)

Both controllers, ES and ER, include a potentiometer for static pressure setpoint adjustment (range: 30…100%).

Installation

Safety distances

The airflow control damper is installed taking into account the required safety distances. Install the unit into ductwork in such a way that the air flow direction through the unit is as indicated with the arrow in the unit casing.



For the pressure control damper the minimum safety distance for the static measurement tab after the control damper is 5 x D. Please refer to job drawings.

The wiring shall be carried out in accordance with local regulations and by professional technicians.

For the power supply of all control options, a safety-isolating transformer shall be used.

The actual measured airflow rate (qv) can be defined by the controller feedback signal (U or U5) and airflow controller nominal airflow (qv_nom).

The actual airflow rate can also be determined from the pictures below.



The actual airflow rate can be calculated as a function of differential pressure at the measurement probe and the measurement probe k factor. The proper k factor can be found in an attachment for the product.

 

qv          actual airflow rate [l/s]
k            k factor value:  W (mm) x H (mm) x 0,001054
Δpm           differential pressure of measurement probe [Pa]

The Halton UKV airflow controller is equipped with a pressure sensor, and there is a very low airflow through the differential pressure sensor of the controller. Therefore, a manual differential measurement manometer can be connected in parallel to the airflow controller (for example with tube T-branches) and both measurements can operate in parallel with continuous control.

If Halton UKV is ordered without factory pre-set minimum and maximum flow values (FS=NA), minimum flow value will be set to 0 and maximum flow value is equal to nominal flow value.
