Lime in drinking water can be detrimental for pipes, fittings and water heaters. JRG Coral force has proven to be an effective natural limestone protection device that does not affect drinking water quality. Thanks to the catalyst granulate used, the biomineralization converts the dissolved calcium and carbonate ions into tiny lime crystals, which are simply flushed out of the system. 

Chemical-free treatment

JRG Coral force does not require chemical treatment. There is no salt or phosphate uptake in the water; the sodium content is not increased any further.

value-bar-icon-3 Efficient heating

When preparing hot water, limescale deposits increase the required energy input drastically. When using JRG Coral force, water continues to be heated in an energy-efficient way.

value-bar-icon-2 Hygienic safety

To protect the JRG Coral force installation from calcium deposits, which are ideal sites for bacterial growth (Legionella), regular thermal disinfections of the granulate are conducted.

value-bar-icon-6 Economic investment

The importance of low operating costs and no consequential damage to heat exchangers or pumps is not to be discounted. The catalyst granulate used with JRG Coral force only needs to be replaced every five years.
