Cooling Tower Cleaning

What is Cooling Tower Cleaning?

Cooling Towers work by moving hot water downward while cold air rises through the system. Over time, minerals in the water, such as calcium, build up on the internal fill surfaces. This mineral build-up, referred to as “barnacles”, restricts water flow and air movement, significantly reducing the systems cooling efficiency.

Our technicians carry out a full internal clean of the cooling tower to remove these deposits using either pressure washing or softening with acid where required. Every clean is performed in accordance with AS/NZS 3666 to ensure compliance and safety. In many cases, cooling towers also require confined space entry protocols, meaning full safety planning is a must.

Is Cooling Tower Cleaning right for you?

Common applications in commercial and industrial settings include:

• Sites with cooling towers showing signs of mineral build-up or reduced efficiency
• Food production or hygiene sensitive sites concerned about Legionella, Listeria or other pathogens
• Sites requiring qualified personnel for confined space entry
• Sites wanting to protect cooling tower assets from damage due to incorrect cleaning methods
