Frenger Ultima 300 – Active Chilled Beam

Ultima 300 is one of Frenger’s latest range of high-performance Chilled Beams. Energy efficiency has been a key driver for such advancements in Frenger’s Chilled Beam Technology.

Ultima 300 is only 290mm deep and 292mm wide and can achieve 525 watts per meter total cooling (based on 10tk and 26 ltrs/sec/m for a 2.4m long beam supplied at 16C with a 100Pa).

The Ultima 300 beam contains a number of Frenger’s patent-pending performance-enhancing features and as can be expected from the Frenger brand, the Ultima 300 beam is designed to be easily tailored to suit the unique parameters of individual project sites, for the optimum product/system efficiencies. This is partly achieved by Frenger’s “burst nozzle” arrangement that not only encourages induction but also reduces noise. Given the size and amount of burst nozzles being appropriately quantified for each project, this provides consistent jet velocities, equal distribution of the air discharge and continuous induction through the heat exchanger (battery). There are no dead spots due to plugging back nozzles from a standard pitch or having to adjust the pressure in the system to suit the number of open standard beams as dead spots and/or reduced velocities decrease their cooling capacities/efficiencies.

Frenger’s beams all have a “closed back”, this means that all induced air (recirculated room air) is induced through the underplate within the room space to avoid any need for perimeter flash gaps and/or openings in the ceiling system. This also provides for a better quality of recirculated air as the recirculated air does not mix with any air from the ceiling void. The induction ratio for Ultima 300 is typically 4-5 times that of the supply air (fresh air) rate.

The Ultima 300 Chilled Beam outer casing is constructed from extruded aluminium and zintec pressed steel. The casing facilitated an aluminium burst nozzle strip (project-specific) and a high-performance heat exchange battery constructed from copper and aluminium. Beams are available in lengths from 0.6m up to 3.6m in 0.1m increments.

In addition to Ultima 300’s high cooling performance capability of in excess of 500 watts per metre, Ultima 300 can operate well and induce at low air volumes, as little as 3.4 l/s/m and even with low static pressure of just 40Pa. Likewise, Ultima 300 can handle high air volumes up to 30 l/s/m and up to 120Pa. Please note however that these high air volumes should be avoided wherever possible and are the absolute maximum and should not ever be exceeded. As a rule of thumb, 25 ltrs/sec/m from a 1 way discharge beam is the maximum for occupancy comfort compliance to BS EN 7730.

The maximum total supply air for the product is limited to 40 ltrs/sec. If the total air volume is more than 40 ltrs/sec, refer to the Ultima active Chilled Beam by Frenger.

Ultima 300 can have integrated heating with seperate connections (2 pipe connections for cooling and 2 pipes for heating).
