COMBI CARE UNI is a new generation hydrodynamic dosing unit designed for the automatic and proportional treatment of drinking water through the use of natural polyphosphate-based mineral salts. Its function is to continuously and reliably prevent the formation of limescale deposits and corrosion in plumbing systems, hot and cold water sanitary circuits, process systems, and water-cooling circuits. It is also suitable for the gradual restoration of systems that are already encrusted or corroded, helping to eliminate existing deposits. Thanks to its internal cartridge, the device constantly releases small amounts of polyphosphates into the incoming water, creating active protection that inhibits the crystallization of calcium and magnesium salts and forms a protective film on metal surfaces. In this way, boilers, heat exchangers, water heaters, and pipes remain protected for longer, reducing the need for maintenance and improving the overall energy efficiency of the system. Manufactured by BWT, a leading water treatment company, COMBI CARE UNI is an effective, economical, and easy-to-install solution for the daily protection of domestic plumbing systems. Its operation is completely hydrodynamic, activated directly by the passage of water, without the aid of electricity or electronics. The ideal choice for those who want continuous protection against limescale and corrosion, with the guarantee of a safe product that complies with drinking water regulations and has been developed by one of the most reliable brands in the industry.
