TwinTec S3 Water Softener

Our water softener

The TwinTec S4 Water Softener has been developed over a period of nearly 40 years, resulting in a product that has been manufactured to the highest standard today. Unlike other products on the market it doesn't shut down to regenerate, with an innovative twin cylinder design, the TwinTec water softener gives luxurious, softened water to your home 24/7. It doesn't require you to battle with heavy bags of salt to refill it, simply drop in the block salt and the softener does the work for you.

A max flow rate of 56 litres per minute ensures power showers and megaflows are no problem. And with a focus on sustainability, the TwinTec S4 is built with no timers, motors, adjustments or complicated programming. It is non-electric, saving energy and offers outstanding efficiency in both salt and water usage.

How water softeners work

A water softener provides your home with luxurious softened water by removing the minerals that exist in hard water areas. The minerals (magnesium and calcium) are picked up when the water passes through hard rock before entering your water supply system.

Through a process of ion exchange, a TwinTec water softener removes these mineral deposits, leaving you with pure, softened water. The non-electric softener is powered by water pressure and the twin cylinders contain resin beads that trap the minerals in them, removing the hardness.
