Limescale & Calcium Removal

Triple7 limescale and calcium removal chemicals are worksafe and eco-friendly alternatives, especially designed for use in closed circuit applications and enclosed environments common in the mining industry. Limescale build-up is a common cause of decreased performance for a wide range of critical mining infrastructure. Limescale also leads to costly equipment failures and increased risks of safety incidents such as boiler overpressures and explosions.

Triple7 limescale cleaners are non-toxic, plant based limescale removers designed for effectiveness and safety to workers, the cleaning surface and the environment.

Triple7 limescale cleaners will not harm equipment and give longer life cycle maintenance and consequent cost advantages.

Mining limescale removal applications include; pipework, cooling towers, heat exchangers, boilers, condensers, wet-scrubbers and chillers.

Removing Scale from Pipework at an Australian Mine

The Problem The water supply system at a remote Australian mine was heavily scaled, causing pipe blockages and resulting in a drop in performance. There is a large pipe network for supplying potable water throughout the mine site and the options were to excavate, remove and replace the pipework or find an alternative way to [...] READ MORE


Cost Savings and Superior Results with a Biobased Limescale Remover | Coal Mine

A coal mine in Mackay was faced with a fire system that was blocked with a limescale build-up. Triple7 Enviroscale Plus easily broke down the scale, outperforming the previously used hydrochloric acid based product. Using the biobased product also removed the risk of corrosion or damage to elastomeric surfaces during the flush.
