The passive beam operates by natural convection, removing the heat load from the room and replacing it with a cooling airflow. The convective airflow (output) increases or decreases in proportion with the heat load within the occupied zone, securing an optimal thermal comfort. Varying sensible cooling output requirements are met by regulating the flow of chilled water through the beam heat exchanger. This is controlled by a combination of room thermostat and water  valve. Operating at elevated chilled water temperatures (to avoid latent cooling), the opportunities for free-cooling are significant.


The chilled beam Halton CPA is installed fully exposed below a ceiling or suspended ceiling.
In order to ensure effective convection, the beam should be mounted at a minimum distance from the ceiling equal to 0.25 x the width of the beam, when installed away from wall surfaces, or 0.5 x beam width when installed close to partition walls.

Each chilled beam is fixed to the ceiling with expansion anchors and threaded drop rods (not included in the delivery). Four assembly brackets are fixed one fifth of the unit length (L/5) away from the end of the beam. There will be six assembly brackets with beam length ³ 3500.
The exact positions of the brackets are adjusted according to the rod position.

The chilled beam position can be easily adjusted both horizontally and vertically. Assembly brackets are supplied as standard in the package.
The contractor shall supply threaded rods and expansion anchors.

Distance from the ceiling

D = distance wall; up to 1,0 x W


Commissioning of the chilled beam system is carried out following standard practice:

  • Fill up and flush the main pipelines
  • Fill up and vent the beam circuits
  • Adjust the flow water temperature set point
  • Adjust water flow rates with the balancing valves in all main pipelines to the correct value
  • Adjust water flows in all chilled beams to the correct value


The Halton CPA chilled beam requires minimum maintenance. It may be necessary to clean the cooling coils every three to five years, depending on room conditions and air quality. The casing may be cleaned with a damp cloth. The cooling coil can be cleaned using a vacuum cleaner.
