Wiltec NW-SOFT-C1 Water Softening Unit with 10 kg Brine Tank and Control Panel

With the fully automatic water softening unit NW-SOFT-C1 water is softened and calcium oxide neutralised.

Hard water is defined by a very high concentration of calcium carbonate. It occurs when the water flows through calcareous rock layers and soils and absorbs ions of the alkaline earth metals. For the determination of the equivalent concentration the hardness forming ions calcium and magnesium are used. Since the composition of the soil and rock layers can vary greatly and some households are also supplied with surface water from reservoirs, the water hardness can vary greatly from one household to another.

In the case of water hardness, a basic distinction is made between three degrees of hardness:
Soft water containing less than 1.5 milimoles of calcium carbonate per litre (mmol/l), which corresponds to 8.4°dH (°dH = degree of German hardness). In the range from 1.5 to 2.5 milimoles of calcium carbonate one speaks of water with a medium degree of hardness and from more than 2.5 milimoles of calcium carbonate per litre the water possesses more than 14°dH and thus is called hard. More detailed information about the hardness of your water can be obtained from your water supplier.

If you use hard tap water as drinking water, the taste differs significantly from that of soft water. Most people find that soft water has a more pleasant taste, even if drinking hard water is by no means harmful to the health. Hard water can also be noticed when showering. It tends to make skin and hair rough and brittle and can therefore be problematic for people with dry skin.

Not only is showering with soft water more gentle on the hair and more pleasant for people suffering from dry skin, but hot drinks allow aromas to unfold better and household appliances such as dishwashers or washing machines enjoy a much longer service life as limescale deposits are reduced to a minimum.

The NW-SOFT-C1 is used to turn your hard tap water into soft tap water.
The NW-SOFT-C1 is capable of softening 500 litres of water per hour. Operating the device is very easy. The pre-existing hardness of the water needs to be selected via the display and the automatic control unit will alter the hardness of the water accordingly.

The water is softened via ion exchange, which is achieved by a special resin inside the softener by mass exchange. This resin is structured in a way that binds calcium and magnesium ions, i.e. the cations, from the drinking water and at the same time displaces sodium ions into the flowing water. This reduces the hardness of the water, but does not affect the original pH value.

Another great advantage of this system is the automatic regeneration of the exchange resin; the device can exchange the cations bound to the resin due to the salt or brine supply of max. 10 kg. The "lime" better known as the calcium and magnesium ions are flushed out of the system as waste water and the regeneration process is complete. Due to this process the resin receives its natural capacity and can be used again.

The only thing that must be filled into the system to ensure the functionality of the resin and make it maintenance free is "normal salt". We recommend regeneration pills since they are easy to use.

Safety Information

• Only use water softeners to treat drinking water in accordance with the specifications. Not suitable for filtering chemically contaminated liquids.
  
• Do not exceed the maximum water pressure. If necessary, use a pressure reducer.
  
• Change the filter parts in accordance with the manufacturer's instructions to ensure the water quality and prevent blockages.
  
• Regularly clean and disinfect the osmosis system as stated in the instructions in the manual.
  
• Protect your osmosis system from frost, as frozen water can damage the components.
  Risk of Electric Shock
  
• Never lift, transport or attach the appliance by the power cable.
  
• Ensure that all cables and connections are undamaged, securely fastened and watertight.
  
• Before initial operation, ensure that the mains voltage matches the rated voltage on the rating plate.
