Caleffi XP - Under-boiler polyphosphate dispenser

The polyphosphate dispenser limits limescale formation in the domestic water system and in the devices connected to it. It is installed on the domestic cold water pipe supplying the instantaneous boiler. It helps to maintain the original heat exchange performance levels of the generator and heat exchanger in the DHW production circuit over time. It also combats corrosion and progressively cleans up systems which are already experiencing some limescale build-up, in addition to susceptible parts.
The dosage of polyphosphates in the water is proportional to the amount of cold water passing through the device.
Equipment for domestic use, for the treatment of potable water.
