Why KTW compliance is important:
Since 1 March 2025, the new legal requirements of the Federal Environment Agency (UBA) have applied to all components that come into contact with drinking water. The so-called KTW-BWGL (assessment basis for plastics and other organic materials in contact with drinking water) ensures that no harmful substances are transferred into the water and that neither its smell nor taste is impaired.
The control valve used has been specially developed for use in drinking water applications and is fully KTW-certified.

Neomeris KTW 32 – Compact water softening at the highest level Soft water for noticeably more comfort: The Neomeris KTW 32 is a powerful cabinet water softener designed specifically for households with up to five people. With an inlet water hardness of 10 °dH, it delivers up to 3,200 litres of perfectly softened water per regeneration cycle. Thanks to the proven ion exchange process, the calcium and magnesium hardness minerals contained in the water are replaced by sodium ions. This effectively prevents limescale deposits – for shiny fittings, soft laundry and optimally protected drinking water equipment. Product benefits at a glance: Simple installation and well-thought-out design The Neomeris KTW 32 impresses not only with its performance, but also with its straightforward installation. The compact cabinet housing can be easily installed in almost any utility room, basement or technical area. The removable cover allows easy access to all components, making installation and maintenance particularly convenient. Inside is a GRP pressure vessel containing a high-quality ion-exchange resin. The housing also serves as a salt storage container for brine production and can hold up to 40 kg of regeneration salt. At the heart of the system is the control valve, which operates using microprocessor-controlled electronics. Settings can be made quickly and easily via an intuitive 5-button control panel and a multifunction display. The robust, screwless valve housing features a practical click system that makes maintenance work considerably easier. The KTW 32 is factory-set to volume-controlled regeneration for optimum performance and economical operation. Intelligent control with night regeneration An integrated water meter measures actual consumption and ensures that the system only regenerates when it is really necessary. Regeneration takes place automatically overnight. Efficient regeneration – automatic and hygienic When the ion exchange resin is completely saturated with calcium and magnesium ions, the system automatically regenerates itself using a concentrated saline solution. This rinses out the hardness minerals bound in the resin and replaces them with sodium ions. The used brine is drain away – the resin is then immediately ready for use again. During this phase, an integrated bypass ensures that tap water remains available. This means that the water supply is maintained in full even during regeneration. Automatic hygiene function – protection during longer breaks To ensure that the system remains hygienic, the KTW 32 automatically performs a time-controlled forced regeneration after no more than 7 days without operation. This function reliably prevents possible contamination of the resin bed – ideal for longer holiday periods, for example. Durable, safe and comfortable Depending on water hardness and consumption, one salt filling usually lasts three to four months. An integrated float valve with buoy reliably protects the cabinet from flooding. The Neomeris KTW 32 combines state-of-the-art technology, simple operation and maximum operational reliability – for permanently soft water and a noticeably better quality of life throughout the entire house.
