The softening of water is a process that totally or partially transforms the salts of Calcium and Magnesium, present in the hard water, into salts of Sodium (soluble and non-encrusting).

The softeners are completely automatic systems that use our particular resin called “Cullion”, selected for a long duration and a minimal consumption of regenerating agent necessary for their reactivation.

The Cullwater softeners, are based on the requirements of the customer and are available in the cabinet, single tank and duplex versions. They can have time command, volume command and specified for water consumption.

The time command makes the regeneration of the softeners start by intervals of fixed days in according to the habitual consumptions of water. If these consumptions are not constant, the regeneration can be late or in advance, resulting in a lot of waste of regenerative agent or causing leak of hard water in the exit from the treatment. In this situation the volumetric command is preferable.

The volumetric command makes the regenerative agent of the softeners start when the resins reach the minimal level of their capacity of exchange, improving the regenerator’s consumption.

The S series, for the softening of the water for drinkable use, respects the italian ministerial parameters for the systems of domestic use. This series of softeners uses a generator of chlorine gas for the auto-disinfection and is provided with a system of mixture of the hardness allowing the installer or the final user to regulate accordingly.
