Active Multi-Service Chilled Beams

Based on Active Chilled Beam technology, Active Multi-Service Chilled Beams (MSCB’s) are connected to both the ventilation supply air ductwork and the chilled water supply. Low temperature hot water (LTHW) can be used as a separate supply (4 pipe) in this system for heating.

A main air handling unit supplies fresh air into the various room areas through the Chilled Beams, which uses the primary air supply to induce room air into the beams heat exchanger. The induced air is then re-circulated into the room, along with the fresh air supplied by patent protected burst nozzle slots along the beam.

Passive Multi-Service Chilled Beams

Based on ‘Radiant’ Passive Chilled Beam technology, Passive Multi-Service Chilled Beams (MSCBs) work purely using chilled water supply to employ both convective (60%) and radiant (40%) principles which are designed to deliver high cooling duties with minimal air movement within the occupied zone.

The ability to cool by radiant means that Passive MSCB’s can provide 40% more cooling at the same air movement velocities when compared to traditional finned coiled batteries. They are ideal where there is a requirement to provide the best possible occupancy comfort levels and excellent energy efficiency.
