Limescale & Calcium Removal

Our low corrosion scale removal systems are extremely well suited to the marine environment where limescale, rust, barnacles, crustacea and other marine scale build-up occur at very fast rates and present unique engineering challenges.

Triple7 limescale removal agents are extremely effective yet are designed to be safe for use aboard vessels where confined spaces and engineering complexity pose unique safety and workflow challenges.

Our eco-friendly formulations are safe for release directly into sensitive marine environments without the need for wastewater treatment. There are no special requirements for handling, storage, safety or disposal when using one of our marine de-scaling agents.

The high tech, low corrosion formulation of Triple7 limescale removers also mean they can be used without dissasembling complex marine equipment and are safe on even the most sensitive surfaces without the risk of damage.

Safe and Effective Condenser Descaling with Triple7 Eco-Scale

Triple7 Eco-Scale was used to effectively remove severe descaling from a condenser.


Triple7 Enviroscale Eliminates Radar Cooling Systems Issues Aboard HMAS Hobart

HMAS Hobart was experiencing issues with biofilm and algae deposits in the radar cooling water systems that are essential for communication. Triple7 Enviroscale was used to eliminate these deposits safely with minimal downtime and no damage to sensitive equipment.


Reducing Hazards and Expense in Heat Exchanger Limescale Removal | Defence Anzac Class

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.
