DUPLEX COMMERCIAL WATER SOFTENERS
Clack WS1 CI TT Metered Control Valve
Duplex water softeners feature two free-standing vessels with a separate high-capacity brine tank for easy salt top-ups. Popular for high-flow applications where 24/7 soft water is required, they are commonly found in hotels, leisure facilities and continuous manufacturing plants with significant water demands. Our systems feature a market-leading Clack WS1 CI TT (1″) metered control valve with PED-compliant vessels and certified food-grade resin to ensure suitability across a broad range of applications – supplied as a complete kit ready for on-site assembly.
What Maintenance Is Required?
Duplex systems are designed to operate with very little maintenance. The salt level should be checked weekly and topped up if required. A monthly check of feed-water hardness is recommended, with the hardness figure being easily adjusted on the valve if necessary. An annual check for leaks or damage is also best practice.
