water treatment units

In the south of the UK, the mains water is very hard which causes limescale and damage to equipment, especially espresso machines.

Your warranty does not cover limescale damage and any service calls will be chargeable. In our water treatment units, in addition to the ion exchange resin (water softening) each unit incorporates a carbon core which also reduces the taste and odour effect of mains drinking water.

We provide a water treatment exchange programme every 6 months, which ensures the correct protection of your equipment. The water treatment unit needs to be chosen based on the throughput of mains water within any 6 month period and these volumes are measured at an incoming water quality value of 425 ppm degrees hardness, and above.

When we install your machine we will test the water hardness and suggest the maximum water throughput to help protect your equipment. You must ensure the CTU is changed before the scheduled date or before the water meter reaches the throughput limit, whichever is sooner.

Our CTU systems utilise a food grade ion exchange media and a 5 micron carbon block final filter. This combination meets the highest standards for the taste and odour requirements for food and potable water applications. In hard water areas a CTU is essential to help minimise costly service bills and to help minimise machine break downs.

Even a thin layer of scale can seriously reduce your equipment's efficiency and affect the coffee taste. Scale acts as an insulator, requiring the boiler to work harder to boil water. This costs more money to run and ultimately leads to machine failure and costly repair bills.

Some effects of a scaled water boiler...

  • More power consumption
  • Lower water temperature
  • Sticking valves
  • Water leaks
  • More stress
  • Business interruption
  • Big bills
