In order to certify the effectiveness of the results, the Physico® anti-limescale water treatment system has been extensively tested and certified by the Universities of Padua and Milan.

The different crystallisation process induced by the treatment leads to a drastic reduction in the strength of cohesion between the crystals, thereby reducing the build-up of limescale.

Results obtained through microbiological tests

Microbiological tests carried out by laboratories certify that Physico® produces a constant and effective bactericidal action which reduces the pathogenic micro-organisms found in water.

Physico® has obtained certification for the validity of the treatment from major research laboratories. A great achievement for those like us at Tecnoacque, who work for innovation and the environment every day. The certification of the tests performed on Physico’s action against the build-up of limescale, as well as on the wholesomeness of the water, is not only a guarantee for users, but also for designers and installers, because they know they can rely on the excellence of Italian research and on acting ethically and responsibly.
