Cooling Towers & Air Handling Units


Many large factories, shops and office blocks have cooling towers associated with their air conditioning units. As there is a risk of spreading legionnaires disease from these units, legally, they must be registered with the local authority. The following groups or companies are on our register:

  • Exchem Organics, Great Oakley Works, Bramble Island, Harwich, Essex CO12 5JW
  • W J Hooker Ltd, Waterside, Brightlingsea, Colchester, Essex, CO7 0AU

Air handling units within buildings may be linked to air conditioning systems. Many modern systems are " Dry" and pose an insignificant risk. However some air conditioning systems are "Wet", i.e. they use a water evaporative cooling system and can pose potential health risks if not properly maintained.

Any person responsible for, or business utilising a water cooled system must carry out a thorough risk assessment in relation to it and must, by law, put in place all necessary procedures, including maintenance, to ensure that it does not pose a risk to public health.

The message is therefore "make sure your air handling units are serviced at appropriate intervals, and follow the instructions by the supplier or manufacturer".
