Displacement metre

Our patented metering system does not use turbines but a pressure differential system, which can cope with low and high flow rates, enabling it to measure down to two drips per second. A water softener powered by water making it efficient in water and salt usage.
The metering system’s efficiency is further improved by operating only with softened water , thus it can never malfunction because of hard water scale.
Each meter is factory set, to provide the correct volume of softened water, relative to the hardness in your area: no on-site adjustment is necessary. It’s sealed, maintenance-free and works impressively quietly.

Manufactured in the UK

The TwinTec S4 uses a unique ultra-fine exchange resin, which along with our twin cylinder system ensures maximum operational efficiency and high flow rate Ion exchange resin is the heart of a water softener. Its job is to remove the calcium and magnesium. The latest technology are micro nano beads of uniform size and so give higher flow rates and greater exchange capacity than other twin cylinder softeners.
