Eco™ - Active Chilled Beam

Eco™ 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.

Eco™ is 227mm deep as standard and can be increased to 267mm deep for higher air volumes. Eco™ and can achieve 1016 watts per meter total cooling (based on 10dTK and 25 ltrs/sec for a beam supplied at 16°C with a 100Pa).

The Eco™ beam contains a number of patented performance enhancing features and as can be expected from the Frenger brand, the Eco™ beam is also 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 entire length of 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.

Eco™ can be used in most types of commercial building where a value engineered solution is preferred such as for ceiling integration. Eco™ units are finished in RAL 9010 (20% Gloss) White as standard.

Eco™ is available in any length from 1.2m up to 3.6m in 0.1m increments and is constructed from zinc coated mild steel for its outer casing rather than extruded aluminium which is utilised for Frenger's products. This is the area where the value engineering has occurred.

The cooling and heating internal components are the same high quality construction for Eco™ as utilised for Compact^® and Ultima^® and as such a similar cooling/heating performance.

The air chamber for Eco™ is the largest in Frenger's product range and can accommodate up to 90 ltrs/sec with its 160mm diameter single air inlet connection point.

Eco™ beams all have a "closed back", thus meaning 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 Eco™ is typically 5 times that of the supply air (fresh air) rate.

In addition to Eco's™ high cooling performance capability of in excess of 1000 watts per meter, Eco™ 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 Eco™ can handle high air volumes up to 30 ltrs/sec/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 2 way discharge beam is the maximum for occupancy comfort to BS EN 7730.

Eco™ 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 90 ltrs/sec/m, which equates to 25 ltrs/sec/m for a 3.6m long beam.

Cooling / Heating for Hospitals and other Healthcare applications needs to be designed as a bespoke solution to fit around the facilities requirements, whilst prioritising the health and Wellbeing of patients and other building occupants.

Frenger Systems^® has a wealth of experience of Healthcare applications stemming back some 80 years when Frenger Troughton Young pioneered the supply and installation of Frenger Heated Ceilings to most, if not all hospitals in the United Kingdom.

Frenger's Eco Healthcare Active Chilled Beam features a closed-back design along with a 'drop down' heat exchanger for easy cleaning of all 4 sides of the heat exchanger from the room side and no cross-contamination of recirculated room air.
