    One of the smallest professional water softeners in our range that is suitable for households of up to 6 people or for premises with an average water throughput of approx. 1.5 m³/h or a short-lived maximum throughput of 2.0 m³/h. Thanks to its small dimensions, it is also very suitable for use in the catering industry, e.g., for a steamer or industrial dishwasher or for placement in kitchen cabinets. An additional advantage is that the softener and the salt container are separate.  For example, you can place the salt container above the ground and mount the softener in another place, such as the crawl space.

    The Diuna Duo Water Softeners are pre-set, fully automatic (except for filling with salt), efficient, economical and maintenance free.

    The Diuna Duo Water Softeners for private and commercial use offer a lot of benefits: soft water protects your appliances, saves energy and is noticeably more pleasant on the skin.
