Harsh acids are corrosive and dangerous with the potential to cause devastating injuries to your staff. Disposing of these substances also creates environmental challenges that can be expensive and time-consuming for businesses to resolve.

In contrast, Triple7 Descalers are totally free of hydrochloric and sulphamic acid; instead, these products combine natural acids with non-toxic surfactants to effectively remove scale build-up. The range is both Worksafe and eco-friendly.

The powerful botanical formulation removes limescale, rust, barnacles and crustacea from virtually any surface, without damaging or corroding the surface material.

Powerful & Versatile
Triple7 Eco-Scale will not harm equipment and gives longer life cycle maintenance and consequent cost advantages. Applications include;

heat exchangers, boilers and condensers
pipes and valves
wet scrubbers

Protects Equipment
Triple7 Eco-Scale’s high performance formulation effectively and easily removes limescale, rust, barnacles and crustacea without damaging sensitive marine equipment.

Unlike harsh caustic cleaners, Triple7 Eco-Scale is free of salts, metasilicates and strong acids; it produces a powerful cleaning action without damaging hard surfaces, seals rubbers, equipment and pipework systems.

Clean Equipment while in Operation
Due to its low corrosion, worksafe formula and low flammability, Triple7 Eco-Scale can often be used to remove calcium and limescale from equipment without dismantling.  This enables safe, simple limescale removal in complicated marine situations where equipment dissassembly is not practical. This also saves on shut-down time, loss of production and labour costs.

Triple7 Eco-Scale has been successfully used to flush heat exchangers and sewer systems onboard marine equipment without removing the exchanger or failed pipework from the circulation system. This saves high removal and reinstallation costs and time whilst allowing faster turn-around, along with a high standard of cleaning.

Enhances System Performance
Triple7 Eco-Scale returns equipment to optimum performance with less maintenance and longer equipment life.  For critical marine applications Triple7 Eco-Scale also helps prevent serious and dangerous equipment failures.

A continual maintenance program will prevent future limescale build-up and equipment down time.
