IntelliSOFT softening plants, Cabinet type
IntelliSOFT softening plants are water treatment equipment designed to remove the calcium and magnesium salts (that could deposit in technical and sanitary systems).
These systems helps you protect your entire home against damages due to limescale, starting with the sanitary installations, boilers, heating systems and appliances, extending their life span and efficiency and reducing the electric power consumption.
Such plants consist of a pressurized tank, equipped with a strongly acid cationic resin in the form of sodium and a salt water tank for the regeneration agent preparation, thus achieving a compact, small sized system.
The diversity of configuration and dimensions available, quarantiees a perfect match for all kind of apartments, houses or other applications where the space meant for equipments is important. The cost – efficiency rate, the modern design combined with the newest technology upgrade the Intellisoft softening systems, from Softena, Sentencia range of products, to some of the best on the european market.
We recommand you one of the most compact softening plants on the market, available in 2 models: standard and elegant.
- IntelliSOFT softening plants – the standard model, part of Sentencia range of products, offers you an ecological and cost – efficient solution.
- IntelliSOFT softening plants – the elegant model, part of Softena range of products, brings you its unique shape, design and dimensions, and by that means allows you to install it in shallow areas, where a normal water softener doesn’t fit: in the garage, under the water heater, under the boiler etc. Furthermore its elegant an modern design makes pleasant its placement on visible areas in the kitchen, bathroom.

This range of products brings several advantages:
- integrated electronic control panel
- easy software-3 step programming
- high-flow control valve
- low salt and water usage
- separate salt lid, easy salt refill
- safety float, double security

The softening plants are a water treatment equipment designed to remove the calcium and magnesium salts (that could form crust deposits in technical and sanitary systems). Such plants consist of a pressurized tank, equipped with a strongly acid base exchange in the form of sodium and of an adjacent salt water tank for preparation of the regeneration agent.
The supply periods of softened water – regeneration are cyclically repeated and are fully automated, being controlled by an electronic scheduler with microprocessor that actuates an automatic valve.
For a proper operation of the softening plant, it is required that the treated water is clear, that is contains max. 2 mg/l of suspended solids, that it has no oils or residual free chlorum and less than 10 mg/l oxidable organic agents, and that the iron / manganese content does not exceed 1 mg/l.

Process operation:
- Working phase: While providing soft water, raw water enters the resin tank through the top dispenser and crosses the resin layer, from top to bottom. In this way ion exchange takes place and softened water exits through the lower distributor to the consumer.
- Aeration: Durind the aeration process the raw water enters the resin tank through the lower distributor and crosses the resin layer in the opposite direction, from bottom to top. This way the resin aeration occurs and used water comes on the drainage line.
- Regeneration phase: The raw water passes through the injector in the control valve and vacuum the brine from the specific tank. Saturated brine solution was diluted about 10%. Brine solution enters the distributor resin tank through the top layer of resin and crosses it to the bottom. In the meantime, regeneration occures the water used for this process passes through the lower distributor and is discharge to drainage .
- Slow wash phase: The slow wash occurs in the same direction as the brine aspiration. This phase starts when the brine tank is empty, and involves the brine excess removal from the resin layer.
- Fast wash phase: The raw water gets into the resin tank through the superior distributor and passes the resin layer from top to bottom, leaving it through the inferior distributor. During this phase the chemicals used for regeneration are removed from the sistem until the required quality water is obtained.
- The brine tank refil: The raw water enters the resin tank through the superior distributor and crosses the layer from top to bottom, then through the inferior distributor and the brine tube into the tank. The water volume needed for brine tank refil is depending only on the time granted for this phase. The water and the salt tablets from the salt tank compose the brine solution that will be used on the next regeneration process.
Alternating Duplex softening plants ensure softened water on a continuous basis, 24 hours out of 24. Such plants consist of two pressurized tanks, provided with strongly acid resin in the form of sodium, and of an adjacent salt water tank for preparation of the regeneration agent. The salt water tank could be located on sideways, in the front or back side of the resin tanks, in such manner that the space occupied by the equipment is maximum optimized.
The periods of softened water supply – regeneration are cyclically repeating and are fully automated, being controlled by a single electronic scheduler with microprocessor (model SXT), that triggers an automatic valve (Fleck model).

The ion-exchange filters (Structural model) regenerate in turn, automatically; while a column runs the regeneration cycle, the other one produces softened water. Once the regeneration of a column is over, this column waits until the other column is exhausted and, afterwards, it automatically passes into production and the exhausted column starts the regeneration cycle.
For a proper station functioning is required a clear water, with a load of suspended solids up to 2 mg / l, free of oils and free of residual chlorine, with less than 10 mg / l oxidizable organic substances and iron content / manganese should not exceed 1 mg / l.
