Water produced especially for Alphacool directly from a high-quality reverse osmosis system. Purified by 5 special filters (one of which is a special reverse osmosis filter), the water is absolutely free of salts, metals and germs, i.e. all those components that are found in normal tap water. The process eliminates chlorine, odours, heavy metals such as lead, copper, cadmium, mercury, etc. Agricultural chemistry, hormones, antibiotics, pesticides, fungicides, herbicides, drug residues, carcinogenic organic chlorine compounds, radioactive substances, asbestos fibres, tar compounds, nitrites, nitrates, bacteria, viruses, fungal spores, cysts. This means that the water leaves no residue whatsoever during evaporation and no limescale deposits are formed. On the contrary: Due to the low PH value of 6.0 - 7.0, Ultra Pure Water even absorbs deposits (up to a certain amount), so that the cooling system remains permanently clean.
