Internal flushing
An environmentally friendly cleaning product used worldwide in shipping, offshore, general industry and energy production. MultiScale dissolves internal deposits and blockages in seawater, freshwater and drainage pipe systems – reducing maintenance and energy costs.

Why it works
- Non-toxic – supports the UN Sustainable Development Goals and ESG standards.
- Safe for all types of plastic and metal.
- Does not damage gaskets or elastomers.
- All cleaning can be done on-site – no expensive dismantling of machinery.
- Reduced energy consumption and fewer unplanned outages.
- Systems without circulation (heat exchangers, single radiators, spirals, condensers) require a separate circulation pump, such as the MultiCIP.
