Anti-scale and anti-corrosion protection for boilers

The DP1 polyphosphate doser provides the water with a suitable anti-scale and anti-corrosive treatment, leaving its potability characteristics unchanged.

It is mainly applied upstream of domestic hot water supply systems, directly at the cold domestic water inlet to the boiler. The DP1 polyphosphate doser has a small footprint, simple and quick installation, low product consumption and low maintenance costs.

Characteristics of polyphosphates

The sodium and potassium polyphosphates inside the container combine with calcium and magnesium ions to form a chemical compound similar to limescale but which cannot adhere to pipe surfaces.

The precipitation of calcium and magnesium and the consequent formation of lime deposits is prevented. 

In addition, polyphosphates are deposited on the surface of the pipes, forming a protective film to protect them from fouling and remove already deposited limescale.
