Eco™ - Active Chilled Beam

Eco is one of the FTF Group's latest range of high performance Chilled Beams. Energy efficiency has been a key driver for such advancements in the FTF Group's Chilled Beam Technology.

Eco is 9" deep as standard and can be increased to 10" deep for higher air volumes. Eco and can achieve 967.4 BTU/hr/ft total cooling (based on 18dTK and 16.1 CFM/ftfor a beam supplied at 60.8°F with a 0.4"H20).

The Eco beam contains a number of Patent pending performance enhancing features and as can be expected from the FTF Group's 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 aluminum 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 11.8.

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 3.9ft up to 11.8ft in 3.9" increments and is constructed from zinc coated mild steel for its outer casing rather than extruded aluminum which is utilised for the FTF Group's other products. This is the area where the value engineering has occurred. The cooling and heating internal components are the same high quality construction for EcoT as utilised for CompactT and UltimaT and as such a similar cooling/heating performance.

The air chamber for Eco is the largest in the FTF Group's product range and can accommodate up to 190.8 CFM with its 6.3" 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 952.1 BTU/hr/ft, Eco can operate well and induce at low air volumes, as little as 1.9 CFM/ft and even with a low static pressure of just 0.2"H20. Likewise Eco can handle high air volumes up to 19.3 CFM/ft and up to 0.5"H20. 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" 16.1 CFM/ft from a 2 way discharge beam is the maximum for occupancy comfort to BS EN 7730.

Eco healthcare Chilled BeamEco - Healthcare™ Active Chilled Beam Chilled BeamEco 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 190.8 CFM, which equates to 16.1 CFM/ft for a 11.8ft log beam.

Eco is also available with a drop down heat exchange battery for easy cleaning to all 4 sides of the heat exchanger - see the FTF Group's separate Eco - Healthcare™ brochure.
