Halo™ 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.
Halo® is only 230mm deep and can achieve up to 1463 watts total cooling (based on a 1.2m long beam with a 10 dTK between room and mean water temperature and 44 ltrs/sec of air 16°C with 100Pa). The Halo™ beam contains a number of Patent pending performance enhancing features and Registered Designs for aesthetic enhancements, all as can be expected from the Frenger brand.
These high-capacity active chilled beams have a small footprint and as such have become increasingly popular as they can free up ceiling area whilst still handling significant heat gains and heat losses. However, the challenge has been to meet these demands whilst still delivering high levels of occupancy comfort. Frenger's Halo™ active chilled beam meets these challenges with its unique, true 360° air discharge characteristic with concealed air discharge veins.
The latest-generation of 360° Active Chilled Beam combines cooling and optional heating function with a revolutionary air discharge system and pattern. By introducing the air with set back air deflector veins further up into the point of discharge rather than being mounted on the underplates like earlier models, this not only improve the 360° diffusion pattern it also vastly improves the products aesthetics. This latest development is a Registered Design in addition to the Patent pending performance enhancing items by Frenger. When compared to traditional 2-way or 4-way discharge pattern by others, Halo™ can deliver a reduction in air velocities of up to 35%.
This optimal method of spreading the air in all directions means the shortest possible air throws are created, resulting in optimal levels of comfort to building occupants.
Halo™ is offered in 3 standard models; "I", "C" and "F".
Halo™ "I" models are for integrated ceiling installation in standard 15 or 24mm exposed tee bar grids (Lay-In grid systems) replacing 600 x 600mm or 1200 x 600mm tile modules and can be used for integration with either "mineral fibre" tiles or plaster board ceilings.
Halo™-"C"-60 and Halo™-"C"-120 are designed for integration into metal clip-in ceiling systems.
Halo™ "F"-60 is designed for free-hanging exposed applications. This is a standard model with an addition factory fitted architectural frame enhancement kit that can be finished in white to match the Halo™ beam, or provided as a different colour to make a feature of the extruded aluminum outer frame.
Optimum Diffusion Pattern
In addition to the flexibility offered by a modular designed small unit, Halo™ has been designed to deliver the most comfortable environment at any given air volume. Traditional active chilled beams with a 1-way or 2-way throw have the potential to throw air at high velocities over long distances, however this may result in low comfort levels - particularly where the air streams from adjacent beams meet and fall downwards into the occupied zone or where beams are located close to walls or partitions.
Beams with a 4-way throw help to alleviate this problem, however the Frenger Halo™ beam takes the concept to the next level with its "true" 360° diffusion pattern.
The substantiality shorter air discharge throws (35%) offered by Halo™ can enable more chilled beams to be positioned into a given room space for higher total heat gains to be offset whilst still avoiding draughts and providing a comfortable environment, compliant to BS EN ISO 7730.
