In a milk processing company, the Coop Company. TREVALLI COOPERLAT di Jesi, the continuous formation of limestone required frequent maintenance of two heat exchangers so that the entrepreneur decided to have both an AQUARING appliance installed on anti-limestone.

The sanitary water exchanger is heated by steam recovered from the process; after three years the heat exchange is still optimal and the heat exchanger has not been subjected to maintenance.

In the second exchanger, well water was used to condense the steam; the water was additived with polyphosphates and every 7/10 days the cold water supply pipe completely clogged with limescale.

Once the AQUARING device was installed, an initial check was made after 15 days: the image shows a layer of about 8/10 mm of soft pulp formed by limestone powder and polyphosphate.

It was therefore decided to exclude the use of polyphosphates and to operate the AQUARING device alone for a further 15 days: below you can see the picture that clearly shows the disappearance of any material deposit.

In the following three years no cleaning intervention was necessary, except for one episode caused by accidental and inadvertent disconnection of the power supply to the AQUARING device !!
