Pumps and pipes effected by calcium and limescale can be chemically treated to remove deposits even if completely blocked using a combination of Triple7 Heavy Duty and Enviroscale.

To remove limescale from heat exchangers, condensers and chillers we recommend chemical treatment with Triple7 Eco-Scale. Triple7 Eco-Scale is a formulation of surfactants and worksafe acids that will not harm equipment or endanger workers.

Removal of limescale build-up can be achieved through mechanical or chemical descaling. Chemical descaling with a limescale remover is usually the fastest and most cost effective option.

Chemical limescale removal is faster, cheaper and more thorough than mechanical methods however there are a few critical considerations when selecting a chemical de-scaling agent.

Limescale (or Calcium Scale) is a hard, off-white chalky substance often found on the metallic parts of water-operated machinery. It is particularly common in machinery and equipment that involves heating elements (such as boilers) or heat transfer elements (such as heat exchangers).

Limescale is also found in metal pipes, pumps, filters and other water equipment to varying degrees, depending on water quality.

The build up of this scale, over time, can severely interfere with efficiency and reliability of machinery, pipework and processes leading to decreased efficiency and costly failures.

A bio-based Triple7 product allowed a large commercial laundry operation to completely remove calcium limescale build up on their filters, whilst saving on labour costs. This worksafe procedure also removed risks to maintenance staff by removing strong acids from their inventory and the removal of grinding wheels/brushes from the process.

Envirofluid was able to provide Rio Tinto with a worksafe organic acid blend which was guaranteed to not erode metal surfaces or create waste water treatment issues. This limescale cleaner achieved optimum descaling without dismantling any item on the system and the wastewater flush was able to be used as a road dust suppressant without further treatment.

Envirofluid was able to provide the Australian Defence Force with Triple7 EnviroScale – a worksafe bio-based limescale remover which was guaranteed not to erode metal surfaces or create waste water treatment issues. Pipework and heat exchanger systems could be flushed insitu without the risk of corrosion or damage to elastomeric surfaces, resulting in very large labour and cost savings for the Australian Defence Force.

The ability to reduce risks, improve outcomes, save costs and reduce environmental impact through the use of a GECA accredited, readily biodegradable, non-hazardous acid based chemistry was a total win for the Australian Defence Force.
