Facot Chemicals guidelines

Standard UNI 8065:2019 6 key points

Water treatment in winter and summer air conditioning systems,

for the production of domestic hot water and in solar thermal systems

Let’s follow step by step the 6 key points of the Standard, which has the following aim:

Go to the depth analisis

1 Set the limits of the chemical and chemical-physical parameters of the water in the plants in order to improve the

performance and safety, to preserve them over time, to ensure long-lasting regularity of operation even to auxiliary

equipment and to minimize energy consumption thus integrating laws and standards in force.

Where to turn?

Through the Facot Chemicals and in particular the Check Service analysis service, available from the best national whole-

salers-distributors, and the Facot Service assistance centers, it will be possible to check the , chemical-physical parameters

and have all the technical support necessary for the efficiency of the installations.

Let’s analyze the water characteristics of:
