Protective Coatings

Cooling tower corrosion may not be evident outside, but inside can be a different story. Introducing RepelCoat, a protective coating system that eliminates corrosion – for cooling towers, fan shafts, pipework, tanks and vessels. We offer a complete corrosion repair and restoration service. Available in Vic, NSW, SA.

The cooling tower environment poses exceptional challenges to steel materials.

Over time, steel must withstand the natural corrosive effects of water, constant aeration, bacteria and a swathe of chemical agents.

Coolclean’s RepelCoat system eradicates corrosion, by forming a hard-wearing protective barrier that bonds with steel and repels corrosive elements.

Surface preparation is combined with advanced epoxy technologies to protect steel in very harsh environments.

RepelCoat – Applications

COOLING TOWER COATINGS (Internal and External)
Basins, casing, fan snout, fill pack supports, drift eliminator supports, fan drives and shafts, pipework, sumps, access hatches
Suitable for cooling towers, condensers, fluid coolers and associated equipment

Talk to us about Protective Coatings

We recommend that the following repairs are not performed on steel cooling towers:

FIBREGLASSING: A lining. Fireglass will not flex with the steel. It will crack and water will leak behind the lining.

MEMBRANES: A lining. Membranes are flexible rubber-type products, which will lift away if cut or scraped. Water will leak behind the lining.

PAINTING: A lining. Paint will not stand up to the harsh conditions within a cooling tower. It will crack, peel and lift away as it is not designed to chemically bond to the steel. Water will leak behind the lining.

CONCLUSION: All linings will fail over time, and they are known to cause significant ongoing issues.

Why is it important to address cooling tower corrosion?

•   Corrosion interferes with water treatment programs and mechanical maintenance.
•   Where there is corrosion, Legionella bacteria is likely to be present. Increased levels of Legionella bacteria compromise risk management, safety and compliance.
•   Once a basin is corroded, the process can accelerate quickly. Without effective intervention, large sections, or the whole tower may need to be replaced at significant cost.

Coolclean coating solutions are suitable for all steel cooling towers, including Aquacool, BAC (Baltimore Air Coil), Coolmaster, Evapco, F Muller, Fibreflow, Fibre Tech, Gatorade, Hamon, Hydrothermal, Lakeside, Linear, Marley, Muller and Radic.
