Air Handling Systems
An air handling system refers to a system where air is recirculated through ducts to remove heat. These systems may incorporate an air-cooling or water cooling system. The water cooling system uses water or another liquid to reduce the temperature of air in the system. The water can provide a favourable environment for growth of microbes such as Legionella if not regularly monitored.
The Public Health Act 1991 requires the occupier/owner of a premise with cooling tower unit/s to notify Council in regards to installation or decommissioning of a cooling tower. Council is also required to keep an up to date register of all water-cooling systems in the Local Government Area under the Public Health (Microbial Control) Regulation 2000. Therefore any alterations made to the cooling tower unit/s or changes in register details must be provided to Council by the owner/occupier within one month of the alteration.
