Progressive Flow

Using the progressive flow feature of the Culligan Smart Controller, softeners can be installed in a chain, and will come on and offline as the flow requires, allowing peak water usages to be managed.

Only regenerate when required – using the optional aquasensor internal probe regenerations can be initiated only when the resin is nearing exhaustion

Resin media

High efficiency Cullex® resin is used in Culligan softener systems. The resin consists of highly porous, amber coloured, plastic beads which are covered with "exchange sites" that preferentially remove hardness ions and replace them with sodium, a "soft" ion. Once exhausted the resin is “regenerated” using a salt water brine solution and the softening process begins again.

Frequently Asked Questions

Hard water is water that contains dissolved minerals such as magnesium, iron and manganese, and most often calcium. Water naturally becomes hard as it moves over and through the earth to either a reservoir or into an underground aquifer. Hard water is probably the most common water problem found in municipal and well water supplies. Hard water can cause what is known as scale (normally calcium carbonate, or limescale as it is more commonly known) to build up inside appliances and equipment that utilise water, but particularly ones that heat the water such as boilers, dishwashers, washing machines, cooling systems etc. This can have a significant impact on energy consumption and efficiency.

Just 1mm of limescale in your hot water system can increase your energy use
by 7%*. The most common and effective treatment for hard water is a water softener.

* Source:

Culligan water softeners use Cullex® ion-exchange resin which act on the specific ions which cause scale, mainly Calcium (Ca2+) and Maganesium (Mg2+) ions. These ions are exchanged for sodium ions.

When all the available sodium Na+ ions have been replaced with calcium or magnesium ions, the resin must be re-charged, or as it is more commonly known regenerated by eluting the Ca2+ and Mg2+ ions using a solution of sodium chloride (brine solution).

In this way the unit can continue to soften the water by simply regenerating it periodically when it becomes exhausted using a salt water brine solution.

Some of the benefits of using soft water

  • Scale reduction
  • Extended equipment life
  • Reduced energy and water consumption
  • Reduced maintenance, chemical and detergent costs
