- ✓Two-column professional water softener for single-family and multi-family homes
- ✓Two water softener columns for uninterrupted soft water supply and optimal capacity utilization

Description
Our DUPLEX twin-column water softener is ideal for very hard water and/or high water consumption.
This fully automatic, dual-column water softener with electronic, water-flow-controlled valve CLACK WS1-TT is easily installed upstream of your existing domestic water supply. The system utilizes the proven ion exchange process to completely remove hardness minerals and thus limescale from your tap water. Unlike our basic softeners, the duplex systems feature a second softening column. This ensures an uninterrupted supply of softened water, as the second column automatically takes over during the regeneration phase of the first. This is particularly advantageous in multi-family dwellings. An integrated safety float valve protects the salt container from overflow, and the fiberglass-reinforced pressure tank withstands pressure surges of up to 16 bar. Thanks to our sophisticated ECO-INJECT SYSTEM, the system saves up to 50% salt while operating at nearly maximum capacity.

Domestic water filter / backwash filter in 1"
A backwash filter should generally be present in every installation. This filters sediments and solids from the drinking water. If you don't have a pre-filter yet, please order one at the same time.
Salt for ion exchange systems
This water treatment system works with the ion exchange process. This means that salt is required to operate. How much salt the system needs depends on the water consumption and water hardness. You can calculate your salt consumption using our online calculator.
Connection sets with intersection 1"
Ideal for all duplex systems in 1" versions.
Resin cleaning and disinfection for ion exchangers
This special solution of preservative and demineralized water ensures that the resin of your ion exchanger is refreshed. Use once a year or after the system has been shut down for a long time.
Installation fee for duplex systems up to 240
Warranty extension for duplex systems
flexible hoses 1"
Ideal for connecting to an existing connection fitting. Please make sure to order two hoses (inlet and outlet).
