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.

Equipped with a ½” swivel brass shank, it adapts to all types of boilers; the built-in shut-off system allows maintenance without the need for other shut-off devices.

A polyphosphate charge is included in the package.

The use of polyphosphate silicates guarantees:

•     Scaling inhibition: helps reduce the formation of adherent deposits of insoluble carbonates on heat exchange surfaces.

•     Attenuation of previous scaling (restorative effect): progressive reduction of the layer of deposits formed in the installations in the absence of suitable chemical conditioning.

•     Corrosion inhibition: hinders corrosive phenomena by facilitating the formation of a protective film on parts in contact with water
