Your questions about the operating principle
Yes. The operating principle has been tested and validated by independent laboratories according to recognized European standards.
The system injects a controlled amount of CO₂ into the water. This converts dissolved calcium carbonate into soluble calcium bicarbonate, preventing limescale from crystallizing and sticking to surfaces.
It prevents limescale without salt, filters, or regeneration, while preserving minerals in the water and reducing maintenance and operating costs.
Correct. The system does not use salt, does not require regeneration cycles, and does not discharge wastewater.
No. The injected CO₂ reacts chemically with limescale; it does not remain as free gas, so the water is not carbonated.
Yes. The water remains fully drinkable and compliant with drinking water standards. Minerals are preserved.
Most users report softer skin and hair, as limescale deposits are reduced and soaps rinse more easily.
Yes. Reduced limescale improves the effectiveness of soaps and detergents, often allowing lower consumption.
The taste may feel slightly fresher or smoother, but the mineral composition of the water remains unchanged.
The system does not remove calcium or magnesium; it keeps them dissolved in a non-scaling form, so measured hardness stays the same.
When correctly adjusted, the system keeps the water in a balanced state and does not increase corrosion risk.
The treated water remains stable when heated, significantly reducing limescale formation in boilers, heaters, and pipes.
Yes, it is an ideal application. Hard water is a hair salon's number one enemy on several levels. For hair: limescale binds to keratin proteins, making hair dry, brittle, and dull. Shampoos lather with difficulty, and treatments lose much of their effectiveness. For equipment: washing basins, taps, and water heaters scale up quickly. For products: limescale reduces the lathering power, leading to overconsumption. SoluCalc converts 100% of limescale into soluble, non-scaling calcium bicarbonate, immediately improving hair product efficiency and protecting equipment.
No, that is a technically false claim. Here is what actually happens: 1. CO₂ is injected into the water and dissolves immediately to form carbonic acid (H₂CO₃). 2. This carbonic acid immediately reacts with limescale (calcium carbonate, CaCO₃) to form calcium bicarbonate Ca(HCO₃)₂. 3. The reaction is complete before the water reaches the tap. At this stage, there is no more free CO₂ in the water — it has already reacted chemically. What remains is calcium bicarbonate, which is a soluble salt that flows away and can no longer form scale, even in hot water up to 95°C.
Your questions about CO2
No. CO₂ is a natural gas already present in drinking water. The quantities used are low and safe.
The system includes a pressure indicator that shows when the CO₂ cylinder needs replacement.
Consumption depends on water usage and hardness, but typically one bottle lasts several months in a household installation.
CO₂ costs are low, usually only a few euros per month for a standard household.
CO₂ cylinders are widely available from beverage gas suppliers, installers, or specialized distributors.
Your questions about the appliance
No regular maintenance is required apart from periodically replacing the CO₂ cylinder.
The appliance is covered by a manufacturer warranty, typically several years, depending on the model and market.
The correct model depends on water hardness, flow rate, and building size. An installer or advisor can determine the appropriate version.
Your questions about installation and adjustment
In normal operation, clogging does not occur. If needed, flushing according to installer guidelines is sufficient.
Adjustment is done during installation based on measured water hardness and flow, using the built-in regulation mechanism.
Installation is carried out by trained installers or plumbers authorized to work with the system.
Yes, both systems are perfectly compatible and complementary. Using an activated carbon filter is ideal for refining drinking water quality by removing chlorine taste and odor, filtering pollutants, and preserving essential minerals. In most cases, these filters are installed directly under the kitchen sink. If you have a centralised filtration system, SoluCalc is simply installed after the filter.
It depends on where your osmosis system is installed. Case 1 — Under-sink installation (common residential use): Totally compatible. SoluCalc protects the entire installation while the osmosis system produces ultra-purified water at one point of use. SoluCalc even extends membrane life. Case 2 — Main entry installation (professional/industrial use): SoluCalc should not be installed before the membrane as slightly acidified water can interact with it. In these cases, CO₂ injection usually happens after the membrane. Consult your installer for the correct setup.
