Function

The variable airflow damper Halton HFB contains an averaging airflow measurement probe, airflow controller and actuator. Airflow is controlled based on actual flow measurement by changing the damper blade position. The airflow setpoint can be modified between minimum and maximum settings by, e.g., a room controller with an analogue signal (0...10 or 2...10 VDC). Flow control damper Halton HFB maintains the required airflow independent of duct pressure variation.

The static pressure control damper option maintains the desired constant duct pressure based on a static pressure measurement.

Product Models

The Halton HFB airflow control damper is available in several versions.
The blade gasket enables airtight shut-off operation, and external insulation is used to attenuate radiated sound into the space.

Control units (CU)

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

Airflow control

  • For supply and exhaust installations. 
  • Complete shut-off function (HFB/G and HFB/I). 
  • Maximum differential pressure over the damper of 1000 Pa. 
  • Operating range: ambient temperature of 0 to 50 ºC. 
  • Ambient relative humidity < 95%, non-condensing.
     

Airflow controller options:
             EM     Halton LMV-D3-MF-F.1 HI (5 Nm - for sizes 100...250)
             EK     Halton NMV-D3-MF-F.1 HI (10 Nm)
             EC     Halton LMV-D3-MP-F.1 HI (5 Nm - for sizes 100...250)
             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.

Electric Reheat Coils

The Halton HFB electric reheat coil is available for duct sizes 100...400 mm, and it is always a single-phase heater (230 VAC, less than 16 A).

Two electric reheater options are available:

  • RM = Electric reheater without internal heating controller, PWM control signal input (230 VAC, pulse width modulation) 
  • RC = Electric reheater with internal heating controller, 0...10-VAC control signal input
     

Both heaters (RM and RC) have two internal overheating protection devices connected in series, one automatic and one with manual reset. This increases heater safety.

The RC heater also includes a built-in alarm relay with potential-free changeover contact for remote alarm monitoring. The alarm is triggered by manual overheating protection or heater power loss.

Ensure that the airflow velocity is above 2 m/s to guarantee proper control function when selecting the airflow control damper and reheat coil.

Electric duct heater operation shall always be interlocked with the fan or with airflow rate measurement through the heater. The power supply to the duct heater must be switched off if the fan is switched off or airflow rate is too low. This function can be connected to the duct heater power supply (switch I for both heaters RM and RC), or in the case of the RC heater, also with potential-free contact P.

Installation

Safety distances

The Halton HFB 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.

200 340 1226   500 2449 8818

 

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 value of the product
Δpm        Differential pressure of measurement probe [Pa]

The Halton  HFB 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  HFB 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.
 

Duct pressure control

The actual measured airflow rate can be defined by the controller feedback signal and airflow controller nominal airflow.

The actual duct static pressure can also be read from the picture:

Specification

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

The tightness of the control damper in closed position conforms to standard EN1751 class 4 and casing tightness to EN 1751/C.
Duct connection includes integral airtight rubber gaskets.

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

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

The damper is equipped with a sound attenuator in order to meet the sound level requirement for the room. As an optional extra, the sound attenuator has an access panel for cleaning purposes.

The airflow controller comprises an electric reheat coil with power supply of 230 VAC. Incorporated within the reheat coil has a safety overheat thermostat with both automatic and manual reset. A 3rd party room controller is needed to control the duct heater with 0...10 VDC control signal.
