The limescale solution for residential buildings
Centralized, sustainable and cost-efficient limescale management for apartment buildings.

When limescale affects an entire building
In residential buildings, limescale is not an individual issue but a collective one. Pipes, shared boilers, heat exchangers, appliances and overall resident comfort are all impacted.

A centralized, salt-free treatment
By injecting food-grade CO₂ into the water supply, SoluCalc prevents limescale buildup throughout the entire collective network. Limescale is converted into a soluble form without chemicals and without altering water potability.

A solution designed for multi-residential buildings
The SoluCalc 2-inch system is designed for apartment buildings and collective installations. Installed at the main water inlet, it treats up to 20 m³ of water per hour and protects all residential units with a single system.
