It is recommended to fill cooling circuit systems in each case with water softened to 5 °dH or with water treated by reverse osmosis procedure, as the limescale separating during temperature change my cause serious problems in the system, reducing its efficiency and impairing its economical operation.

In case of open cooling circuit systems, it is advisable to stabilise the residual hardness of the treated water, for which we recommend our DinaFlow P-F product.

In case of open systems, the prevention of the contamination and the algal bloom of the water are indispensable. The biological depositions forming on the convection surfaces significantly deteriorate the efficiency of the system.
For this purpose, we recommend our DinaFlow Biocid F product that provides protection against biological contamination in closed systems as well, dosed proportionately to the make-up water.

The functions of the two above products are combined in tour product named DinaFlow T-Biocid, which provides a complex solution to protect open cooling circuit systems.
