Cooling Towers


The internal piping of a cooling tower collects biofilm, slime, rust, and scale from the water it uses.

These weaken the heat exchangers of their efficiency costing time and money to clear the built up residue and fix the problems caused by the corrosion.


  • Flushing: Frequent flushing to clear the internal components of biofilm, slime, and rust or scale costs thousands of dollars and can put a cooling tower waiting for repair for days at a time. This frequent maintenance causes unneeded disruption for building residents and unneeded costs for building managers.

  • Chemical Inhibitors: Chemical inhibitors can be purchased to reduce the growth of biofilm and reduce rust, scale and corrosion. These chemicals can reduce the lifespan of components in the cooling tower and add another unneeded cost to building maintenance budgets.

  • Enzymatic Cleaning: Evaporative cooling systems are ubiquitous with biofilm. It is known that there is a high risk of Legionella with biofilms therefore the ability to control biofilms is essential in controlling the risk of Legionella outbreaks. Enzyme cleaners are expensive and need to be used consistently in order to keep biofilm in check.

  • Electricity Usage: Biofilm, slime, rust, and scale all sap cooling systems of their efficiency. This causes more wear and tear on components and continuously increases operating costs from increased electricity usage.
