Calcium Treatment Units (CTU's)

Calcium treatment units offer a way to remove hardness minerals from water to stop limescale while keeping water drinkable. As well as this, they improve the taste of incoming feed water with carbon filtration, meaning they are ideal for equipment such as espresso machines, combination ovens, water boilers and vending machines.

Calcium Treatment Unit Information

CTU's use the same ion-exchange process as a water softener but instead of exchanging calcium and magnesium ions for sodium, a CTU utilises hydrogen, meaning water is still drinkable.

As well as an ion-exchange process, the incoming feed water undergoes carbon filtration to reduce chlorine taste and odours, further improving the quality of the water.

Calcium treatment units are especially suited for use on commercial equipment such as coffee and espresso machines, combination and steam ovens, water boilers, ice machines and vending machines.
