X-Wing® - "Radiant" Passive Chilled Beam

X-Wing is one of The FTF Group's latest range of next generation Chilled Beams. Energy efficiency has been a key driver for such advancements in The FTF Group's Chilled Beam Technology.

X-Wing is only 4.8" deep and can achieve up to 1162.5 Btu/hr as an exposed passive "Radiant" / convective cooling unit and up to 49.6 BTU/hr/ft² when concealed behind an S5046 perforated metal ceiling (both sets of maximum performance are based on 18dTF).

NB. The above performance figures are waterside cooling and no inclusion made for any additional cooling effect from any separate supply air system for respiratory requirements.

X-Wing contains a number of Patent pending performance enhancing features, as can be expected from the FTF Group brand.

X-Wing is constructed from copper and aluminum and is 100 percent recyclable. The copper coil is produced byThe FTF Group's in house fully automatic bespoke "state of the art" serpentine bending machine. This produces seamless sinusoidal copper coils (without any joins) up to 19.7ft in length, with up to 12 water passes at 2.8" tube centres. The aluminum radiant "wings" are produced in house by bespoke power press and roll forming machines, all of which are then assembled by The FTF Group's fully automatic CNC controlled machine which mechanically bonds the "radiant wings" to be in metal to metal contact with the seamless copper waterways.

 

The finished products are hydraulically tested to 246.6 Psi positive pressure as standard before automatic machine wrapping and packaging.

 

The FTF Group, have automated the vast majority of processes for this particular next generation product to ensure that the highest levels of quality are both repeatable and consistent at all times.

 

Function

 X-Wing provides cooling by both convection and "Radiation". The radiant proportion creates no air movement, the only air movement comes from the convective proportion. As cold water passes through the chilled beam the warm room air is cooled against the beam's cooler surfaces. This cooled air, which is heavier due to it's higher density, then streams through the punched louvres in the radiant wings and percolates through the small ceiling perforations into the room space below (when concealed). In this way air is circulated within the room, with warm air from the room being continually replaced by cooled air.


In addition to this convective cooling process, the cold surfaces of the beam (the radiant wings / 4 per waterway) also absorb heat radiation from the building occupants and the warmer surrounding surfaces. X-Wing's radiant quotient is approximately 40% of the total cooling effect (the other 60% of cooling being generated by the convective cooling effect described above). The ability of X-Wing to cool by radiation means that, when compared to a finned tube battery, X-Wing can deliver 40% more cooling without any additional risk of draft.
The efficiency of the convection process, coupled with the ability of the product to exchange energy by way of long-wave radiation, means that X-Wing retains a high cooling effect even when the air temperature in the room is relatively low (e.g. at night or when the building is unoccupied). In this way large amounts of cold energy can be stored in the building structure during low load periods, and used to offset heat gains when the need arises.

 X-Wing Chilled Beam - No Joints

At a glance

  • Shallow Depth unit (only 4.8").
  • Only 65mm clearance required behind unit and as little as 9.9" total ceiling construction.
  • Widths available 15.7", 21.3", 26.8" and 32.3".
  • Lengths available 3.9ft up to 19.7ft in increments of 3.1".
  • Can be installed exposed or ideal for "concealed" applications such as behind perforated metal ceilings or within architectural metal ceilings such for ceiling integration or freely suspended Multi Service Chilled Beams.
  • Eliminated risk of water leakage. No joints in the copper coil, just one continuous serpentine for all product widths up to 13.1ft long and up to 19.7ft long for up to 1.8ft wide models (only 2 joints for 2.2ft and 2.7ft wide models over 13.1ft in length).
  • Specialist black coating for smooth, long lasting, easy to clean, uniform finish that increase the radiant absorption coefficient for the product.
  • 40 percent more allowable passive cooling for X-Wing without increased draft risk, this is due to X-Wings "Radiant" quotient as compared to passive fin coil convective cooling products by others.
  • Can be installed above light fittings with no loss of performance.
  • Provides indoor climate in accordance with BS EN ISO 7730.
