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

Product models

The Halton UKV airflow control damper is available in several versions.

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

Airflow controller options:
EM      LMV-D3-MF-F.1 HI (5 Nm)
EK       NMV-D3-MF-F.1 HI (10 Nm)
EC        LMV-D3-MP-F.1 HI (5 Nm)
EE        NMV-D3-MP-F.1 HI (10 Nm)
EG        GLB181.1E/3 (10 Nm)

Controllers EM, EK, EC and EE 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.

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.

Minimum airflow rate of 1 m/s – with controller models of EM, EK, EC, EE

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.

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.

Specification

The pressure-independent variable airflow control damper shall be made of galvanised steel, with an airflow measurement probe of aluminium.

The tightness of the control damper in closed position shall conform to standard EN1751 class 1 and casing tightness to EN 1751/C.

The management damper section shall contain airflow measurement, flow controller and damper actuator.

Design airflow range limits shall be calibrated at the factory.
Controller settings shall be adjustable on site with a PC or a handheld tool.
The airflow controller shall have control signal input 0…10 VDC or 2 …10 VDC and output 0…10 VDC or 2…10VDC for airflow feedback.
Supply power shall be 24 VAC.
