Automatic water softener COMPACT SOFT-VAK 25 (flow rate 1,000 – 2,000 lit/h)

Automatic water softener COMPACT SOFT-VAK 25

CWG VAK COMPACT water softeners are the perfect solution for households struggling with hard water and the effects of limescale. These compact and efficient devices use advanced ion exchange technology to remove calcium and magnesium , the minerals that cause limescale deposits on taps, showers, heaters and household appliances.

SOFT-VAK water softening systems prevent common water problems, including limescale (or scale) made of calcium carbonate and other aggressive minerals such as iron and magnesium. These deposits cause hard water, which dries out skin and hair. When one of these devices is installed in a home, it works to soften the water coming out of every faucet, reducing or completely eliminating these aggressive minerals.

How does the CWG VAK COMPACT softener work?

1. Hard water enters the device and passes through ion exchange resin .

2. The resin binds hardness minerals and replaces them with sodium , softening the water.

3. When the resin capacity is used up, the device is automatically regenerated using a saline solution .

4. The process is fully automated , silent and imperceptible to the user.

It improves the quality of drinking water in your home and leads to healthier skin, hair and nails after bathing. Our water softeners work by either extracting heavy minerals from water using a process called ion exchange or by neutralizing these minerals so they cannot bond with each other.

Advantages of the VAK COMPACT model:

• Compact size: ideal for installation in a kitchen cabinet, basement or utility room.

• Automatic management: digital control, simple programming and display of regenerations.

• Low consumption of salt and water for regeneration – ecological and economical.

• Reliable technology and long device life.

• Models available for different capacities and family sizes.

Too much limescale in water not only reduces its quality, but is also responsible for calcified pipes and appliances, for example in dishwashers and washing machines. Without a water softening system, appliances lose their performance over the long term, leading to their failure. With a water softening system, you create the ideal basis for softening water and reducing hardness-causing substances such as magnesium and calcium to a minimum.

Ideal for:

• Apartments and houses with 2–6 members .

• Areas with high water hardness (15–30 °dH).

• Customers looking for a compact, quiet and reliable water softener .

Compact water softening systems in a compact design stand out in particular with their narrow, space-saving construction, as the ion mass container and control unit (control head) are built into a compact housing as a salt container.

The compact soft-vak 25 water softener system works according to the ion exchange process, i.e. it exchanges the “hardness minerals” calcium (Ca 2+ ) and magnesium (Mg 2+ ) with sodium ions (Na + ). In the process, it removes limescale from your water.

The Compact system consists of a housing with a removable movable cover. The structure integrates a GRP container filled with high-quality ion exchange resin. The system housing serves as a container for tableted salt for the regeneration of the device, where it prepares a brine solution and can accommodate a salt supply (15 – 60 kg max. depending on the device model).

Maintenance and salt consumption

Maintenance is reduced to occasional refilling of tableted salt in the tank. The device prepares the salt solution and performs regeneration itself, so there is no need for daily monitoring. Softer water extends the life of water heaters, washing machines and heaters because it prevents the accumulation of scale, which directly reduces breakdowns and energy costs.

Who is the compact soft-vak 25 water softener for?

SOFT-VAK 25 is the largest model in the Compact line and is intended for households with moderate to high water consumption. Model 25 offers the best price-to-salt ratio and performance for apartments and single-family homes. Hard water passes through a high-quality ion-exchange resin that binds calcium (Ca²⁺) and magnesium (Mg²⁺) ions — the minerals responsible for limescale formation — and replaces them with sodium ions (Na⁺). The result is soft water at every tap in the home. Hard water enters the device and passes through an ion-exchange resin. The resin binds hardness minerals and replaces them with sodium, softening the water. When the resin capacity is used up, the device automatically regenerates using a saline solution. The process is fully automated, silent and imperceptible to the user.
