DADANCO's innovative technology, incorporating multi-lobe nozzles and improved internal ducting, has been used in dozens of buildings in Australia, New Zealand, Singapore and now Europe to improve existing induction air conditioning systems.

The radical nozzle design lowers noise levels typically to between NR 28 and NR 35 and vastly improves the entrainment ratio of induction units, dramatically improving comfort conditions.

Extending the application of this technology, DADANCO recently developed an Active Chilled Beam (ACB) system that greatly improves air-flow distribution and comfort conditions while significantly reducing noise and operating costs.

A DADANCO ACB system reduces the typical energy consumption of the primary air fan by approximately 65-80 percent of the energy consumed by a fan operating with an all-air system. High-efficiency DADANCO nozzles installed in ACB systems lower the total ducted conditioned air requirements to between 20-35 percent.

Combined with the HDP (High Driving Potential) method of air conditioning, ACBs will maintain the air in the conditioned space at a prescribed set point - for example 23(C and 50% relative humidity - and are suitable for conditioning air in all types of buildings, in all climatic regions in the world. DADANCO recently installed and ACB system at the Club Robertson Walk, Singapore.

ACB systems are low profile and require smaller air ducts allowing ceiling space to be as low as 350 mm in new buildings. This space saving, extrapolated over a number of floors in a new construction, means that 11 floors can be created for every 10 conventional floors, without increasing the height of the building.
