Demineralized water equipment

Water softening equipment, that is, equipment that reduces water hardness, mainly removes calcium and magnesium ions in water. When the incoming water is deep well water or the hardness of the water source is very high, the function of using softening water equipment is to remove the calcium and magnesium ions in the water. , reducing calcium and magnesium ions in water. In the process of softening water, softening water equipment cannot reduce the total salt content in water. It is widely used in hot water boiler systems, heat exchange systems, industrial cooling systems, central air conditioning systems and other water equipment systems.

Application Industrial boilers,central air conditioners,heat exchangers,printing and dyeing and other industries.
Filter media Calcium and magnesium ions in water

Working principle

The softening water equipment is composed of automatic softening water controller,salt box, strong acid sodium ion cation resin,resin tank (usually it’s stainless steel resin tank and glass fiber reinforced plastic resin tank),and water softener accessories.With the control of water flow and time,commands are sent to solenoid valves or multi-channel servo valves to complete the water supply and regeneration of softened water equipment.It’s the most widely used for hard water softening treatment equipment in industrial boilers,cooling circulating water,steelmaking,steel rolling,large transformers,civil hot water boilers, etc.


  • Demineralized water equipment advantage

    Demineralized water equipment
    Let the raw water pass through the anion and cation converter to remove calcium, magnesium.



    The wall of the PVC pipe is very smooth,it is not easy to scale after long-term use,has good water tightness,and is resistant to corrosion.

  • Demineralized water equipment advantage

    With the control of water flow and time,commands are sent to solenoid valves or multi-channel servo valves to complete the water supply.


    Easy operation:

    With fully intelligent settings,unmanned operation can be realized,and the working status can be directly observed on the control panel,without professional guidance.

  • Demineralized water equipment advantage

    The exchange tank lined with non-toxic PE plastic and the salt box made of PE are sufficient to ensure the excellent performance of the equipment such as corrosion resistance.


    PE material salt box:

    Made of high-quality polypropylene material,the product is resistant to acid and alkali,not easy to age,and has a long service life,ensuring that the water quality test meets the national drinking water standard.

  • Demineralized water equipment advantage

    High degree of automation, stable water supply conditions and long service life. The whole process runs automatically, only need to manually fill salt regularly.


    Intelligent control:

    The demineralized water equipment realizes the automation of the ion exchange and resin regeneration process through the program control device,which does not require special personnel to operate and is easy to be installed.
