The Cillit-55 is used for the protection against limescale and corrosion, as well as for the gradual reintegration of hydraulic installations and underlying circuits: hot water producers, wall boilers, thermal boilers - hot water side for consumption, hot and cold water boilers, hydrosanitary installations for cooling circuits with water to lose circuits washing air machines with water to avoid water water pipes to avoid water pipes to avoid water pipes to avoid water pipes to avoid water pipes to avoid water pipes to avoid coal precipitation In the distribution network, in case of very hard water or with special characteristics open process water distribution circuit in the industrial field Cillit-55 is a metered and studied combination of plant polyphosphates and sodium with the purity required for use in the food sector. Cillit-55 is a product with a high degree of stabilization of hardness salts and is used to protect the production and distribution of hot and cold water from encrustation. The Cillit-55 is also used to protect installations against corrosion priming and restore old windows that are already embedded or corrosive. The duration of the sanitation depends on the condition of the installation, the amount of fouling present, the possible presence of corrosive bodies in place and their advance state. The restoration of a healthy water system requires careful monitoring of the facilities, we recommend periodic water analysis, installation of inspection records, etc.
