Why do you need a CTU?
Calcium treatment units (CTUs) provide effective filtration against scale-causing minerals found in ‘hard water’, such as calcium and magnesium. Over time, limescale that builds up in steam ovens or coffee machines can lead to breakdowns and shortened lifespans.
A CTU prevents limescale build-up by treating water before it reaches your equipment. Incoming water is fully conditioned before it is used for coffee making or steam cleaning processes.
Why choose our CTU systems?
Calcium treatment units are highly beneficial for cafés and commercial kitchens, ensuring high-purity water is continually available to prevent the effects of limescale.
