Frenger - Product Update for X-Wing® by Frenger

Cooling Systems - Chilled Beams - Chilled Ceilings - Passive Beams

Frenger Chilled Beam

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 124mm deep and can achieve up to 300 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 8 Δtk ).

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 Frenger’s 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” serpentine bending machine. This produces seamless sinusoidal copper coils (without any joins) up to 6m in length, with up to 12water 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 and thus providing 100% encapsulation of the waterways for optimum transfer of energy from the radiant wings to the copper waterways.

  • One complete sinusoidal coil with no joints – No chance of leaks
  • Increased “radiant” quotient to 40% due to increased “radiant” surface area
  • Shallow Depth Construction (only 124mm).
  • Only 2 pairs of drop rods per beam up to 2.4m long (3 pairs drop rods for longer length beams)
  • Up to 300 W/m with air velocities below 0.25m/s directly below the beam due to 40% “radiant” quotient.

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.
