Novel technology, incorporating multi-lobe nozzles and improved internal ducting, developed by Dadanco Pty Ltd (SA) has been used in dozens of buildings in Australia, New Zealand, Singapore and Europe to improve existing induction air conditioning systems. The radical nozzle design lowers noise levels (NR 28 to NR 35) and vastly improves induction units' entrainment ratio, breathing new life into old buildings, reducing operating costs and dramatically improving comfort conditions.

By extending the application of this innovative technology, Dadanco has developed a new product, Active Chilled Beam (ACB), that is ideally suited for air conditioning systems in new buildings.

Dadanco Active Chilled Beams greatly increase room air flow distribution and comfort conditions in the conditioned space while significantly reducing operating costs. For example, by incorporating the high-efficiency properties of the new nozzle technology into Active Chilled Beam systems, only 20% to 30% of total air need be distributed around a building.

When employing Active Chilled Beams in a system, the typical energy consumption of a primary air fan is only 35% of the energy consumed by a fan operating with an all-air system.

Active Chilled Beam systems are low-profile and require smaller air ducts which allow a reduction in up to 300mm of ceiling space in a typical office building. This space saving, extrapolated over a number of floors in a new construction, means that an extra floor can be created for every ten floors planned, without increasing the height of the building.

Dadanco Active Chilled Beams, combined with HDP (High Driving Potential) method of air conditioning, provide the means for conditioning the air in all building types, in all climatic regions in the world, maintaining dry bulb temperature of 23(C and 50% relative humidity.
