Water softening

We offer water softening systems and accessories:


We carry out pipeline installations.


Advantages of water softening:

Reduces the limescale build-up on machines and appliances (dishwasher, washing machine, coffee machine, kettle, etc.) Reduces the consumption of detergents and dishwashing liquids,

Improves the taste and appearance of many foods and drinks.

Softened water is also ideal for use in reverse osmosis systems to remove environmental toxins such as PFAS, as it significantly extends the lifespan of the membranes.


Softened water is also better for irrigation, saving costs.
