With JUDO Bio-balance, JUDO presents an environmentally friendly limescale protection system that has been specially developed for the requirements of the housing industry, the commerce and industry. The product series uses the highly effective Bio-Carat^® process to provide reliable protection against limescale deposits throughout the entire drinking water system, thereby making a lasting contribution to maintaining the value of real estate. Thanks to its low-maintenance and cost-efficient operation, the system reduces operating costs and makes a valuable contribution to environmental protection. 

Winnenden, March 2026 – Repairs and renovations to drinking water installations due to limescale deposits are a major cost factor in the housing industry – as well as in commerce and industry – that can be avoided. It is not without reason that the German standard DIN 1988-200 recommends stabilization or softening for water hardness levels above 14 °dH (equivalent to around 250 ppm CaCO₃) as the problems caused by limescale precipitation are clearly increasing. Those who decide to maintain the original water composition will find effective system technology for hardness stabilization in the JUDO Bio-balance series.

With the highly effective Bio-Carat^® process based on established seed crystal formation, the systems guarantee sustainable, effective limescale protection for existing buildings. This not only facilitates the maintenance of residential complexes, but also saves unnecessary costs. This is because limescale-free heat exchangers increase energy efficiency: for every millimeter of limescale, energy consumption increases by approx. 10%. At the same time, it prevents malfunctions or failures of fittings and water-carrying technology, as well as clogged pipes due to calcification. Such cross-sectional narrowing of the pipes causes a reduction in flow and pressure losses. This in turn weakens the water jet from shower heads and other fittings, which can greatly reduce user comfort.

How does Bio-balance work? At the heart of the system is the Bio-Carat^® process: it stabilizes calcium and carbonate ions dissolved in the water, preventing them from settling in the form of limescale on the inner walls of pipes, heat exchangers, and fittings. Instead, they are simply flushed out each time water is drawn. This is made possible by the use of granules specially developed by JUDO. So-called seed crystals form on the surface of these granules. Other calcium and carbonate ions dissolved in the drinking water tend to attach themselves to these crystals rather than hardening into limescale. Once they have reached a certain size, they are continuously released into the drinking water system. Further calcium and carbonate ions can then attach themselves to these microscopic seed crystals until they are finally flushed out. The effectiveness of the system is guaranteed in accordance with DIN 3607 and has been proven to reduce the negative effects of calcareous water in drinking water installations.
