"Radiant" Passive Chilled Beams

Frenger's X-Wing chilled beam represents the very latest development in passive beam technology. X-Wing employs convective and "Radiant" cooling principles and is designed to deliver high cooling duties (up to 370 watts per meter) with no noise and minimal air movement.

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 its higher density, then streams through the punched louvres in the beam and percolates through the small ceiling perforations into the room space below. In this way air is circulated within the room, with warm air from the room being continually replaced by cooled air.

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

X-Wing is only 125mm deep and can achieve up to 370 watts per meter as an exposed passive "Radiant" / convective cooling unit and up to 170 watts/m² when concealed behind an S5046 perforated metal ceiling (both sets of maximum performance are based on 10dTK).

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 Frenger brand.

X-Wing is constructed from copper and aluminium and is 100 percent recyclable. The copper coil is produced by Frenger's in house fully automatic bespoke "state of the art" full CNC serpentine bending machine. This produces seamless sinusoidal copper coils (without any joins, hence no risk of water leakage) up to 6m in length, with up to 12 water passes at 70mm tube centres. The aluminium radiant "wings" are produced in house by bespoke power press and roll forming machines, all of which are then assembled by Frenger'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 17 bar positive pressure as standard before automatic machine wrapping and packaging.


Frenger, 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.
