The duplex softener is used for automatic and continuous water softening in industrial applications. It is equipped with one Clack main control valve per pressure tank, one brine tank and monodisperse quality exchanger resin. The industrial controller ICI provides an integrated Modbus RTU interface. The regeneration is time or quantity controlled, optionally a quality controlled operation is possible by combination with an online measurement of the water hardness.

Benefits

• High-quality controller in industry standard
• Softening to < 0.1 °dH with full brining
• Continuous soft water supply
• High operational safety due to robust, independent central control valves (operation in single mode possible in case of failure)
• Modbus RTU interface already integrated

Applications

• For continuous soft water supply at high flow rates
• With online hardness measurement suitable for fluctuating raw water quality and particularly safe against hardness breakthrough
• Due to integrated Modbus RTU interface ideal for industrial applications
