Frenger's unique range of active chilled beams utilise the very latest technology to deliver unrivalled levels of performance and flexibility. The beams can deliver cooling, heating and fresh air requirements, with the water-driven products inducing 4-5 times as much room air as fresh air supplied. The conditioned air is then introduced into the space in a whisper-quiet directional or bi-directional manner. The Frenger units have side-mounted air chambers that facilitate high cooling capacity in very compact dimensions and with relatively low supply air volumes. The units will operate effectively with supply air volumes of just 3 litres/second/linear metre (typically equating to just 1 l/s/m2). The Professor beam is only 120mm deep and delivers cooling of up to 350 watts/linear metre, whereas the Polaris beam is just 230mm deep while delivering up to 650 watts/linear metre of cooling capacity. The units are designed to fit easily within the most common ceiling types, and have removable faceplates that can be perforated to match a perforated metal ceiling system. This removable faceplate also provides access to factory-fitted motorised valves, drain cocks and controls. The Polaris and Professor beams are designed to induce all room air through the removable faceplate, and there is consequently no need to provide a return air path through the ceiling system itself. The air being introduced into the space via the beam will entrain to the ceiling tiles as a result of our patented Coanda nozzles, so preventing dumping of air below the chilled beams. Our nozzle technology also enables us to determine and factory-set the airflow and dispersion characteristics of the unit; Frenger can even offer units with differing airflow and dispersion properties from either side of the beam. Frenger work with the design team to create the most comfortable environment, in which air velocities do not exceed 0.25m/s in the occupied zone.
