Water softening for apartment buildings

Do you need lime-free water in all your homes? No problem. Our water softeners are available in various sizes with up to 2" connections. The water softener is simply installed on the main water pipe. The water flowing through is immediately softened and no more limescale can form. All you have to do is refill the water with salt regularly.

Our Duplex and Duplex-Pro water softeners are particularly suitable for multi-family homes. Even when several families use water, these water softening systems excel and provide soft water 24 hours a day. With two fully functional softening columns, you are also equipped for high peak consumption.

How do the Duplex water softeners work?

Every water softening system has a certain capacity. If the capacity of one column is exhausted, it is regenerated and the second column takes over. The regeneration is fully automatic and takes around 1 - 2 hours per column. In duplex systems, the system works in oscillating mode, which means that the system switches between the columns independently. The softening columns should be changed at intervals of 1 - 2 days, depending on water consumption.

The resin cartridges in your Basic 40 softening system generally do not need to be replaced because they regenerate themselves. The regeneration of the resin is an automated process that takes place during the cleaning cycles of the system. Here are some details:

  • Regeneration process: During regeneration, the resin is flushed with a salt solution, which dissolves and removes the accumulated calcium and magnesium ions (which are responsible for water hardness) from the resin. This “renews” the resin and can be used effectively to soften water again.

  • Regular cleaning: This regeneration is carried out regularly, depending on the amount of water used and the hardness of the water. In a 4-person household with a water hardness of 20° dH, the system will regenerate more frequently to ensure efficiency.

  • No replacement necessary: As long as the system is properly maintained and the regenerating salt is topped up regularly, the resin cartridges do not need to be replaced. However, you should regularly inspect and maintain the system to ensure its longevity and optimal performance.

  • In summary, the resin cartridges in your Basic 40 system are maintained effectively by the built-in regeneration process and therefore do not require regular replacement.

    It is best to let the salt empty until the water is visible.
    Then refill and ideally not full to the brim so that there is not too much weight on the salt.

    If you keep filling the container without waiting until you see the water at the bottom, clumps can occur.

    According to the DIN standard, maintenance should be carried out by a specialist at least every 12 months to ensure optimal function and safety of the system.

    However, our water softening systems are designed to be so reliable that many customers carry out regular checks themselves. As long as the system is working properly and no problems occur, there are no legal requirements that make maintenance mandatory. Nevertheless, we recommend checking the system regularly and calling in a specialist if necessary to ensure long-term safety and efficiency.
