Compact™ 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. Compact™ is only 133mm deep and can achieve up to 1092 watts per meter total cooling (based on 10dTK and 26 ltrs/sec/m for a 1.8m long beam, supplied at 16°C with a 100Pa).
The Compact™ beam contains a number of patented performance enhancing features and as can be expected from the Frenger brand, the Compact™ 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 the "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 amount of open standard nozzle sizes as associated with many competitors' active beams as dead spots and / or reduced jet velocities decrease their cooling capacities / efficiencies.
Heat exchanger batteries are also fitted with extruded aluminium profiles to not only enhance performance but also provide a continuous clip on facility for the underplates. This arrangement keeps the underplates true and flat for long lengths, even up to 3.6m.
Compact™ 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 of Compact™ is typically 4-5 times that of the supply air (fresh air) rate.
The Compact™ Chilled Beam outer casing is constructed from extruded aluminium and zintec pressed steel. The casing facilitates 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 1.2m up to 3.6m in 0.1m increments. Typically 0.6m wide (0.5m wide is also available).
In addition to Compact's® high cooling performance capability of in excess of 1000 watts per meter, Compact™ can operate well and induce at low air volumes, as little as 3 l/s/m and even with a low static pressure of just 40Pa. Likewise Compact™ 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 l/s/m from a 2 way discharge beam is the maximum for occupancy comfort compliance to BS EN 7730.
Compact™ can have integrated heating with separate connections (2 pipe connections for cooling and 2 pipes for heating).
The maximum total supply air for the product is limited to 50 ltrs/sec. If the total air volume is more than 50 ltrs/sec or if you require increased heating performance, refer to the Ultima™ active chilled beams by Frenger. Visually both units appear identical from the underside.
