WS1.5” duplex water softeners supply treated, softened water at a flow rate up to 10m3/hr. These softeners are used to keep larger RO installations supplied with soft water, suppling manufacturing equipment that uses heat exchangers or where a constant stream of soft water is required for manufacturing. Soft water is supplied twenty-four hours a day, seven days a week.
A WS1.5 duplex softener utilises a two vessel & two brass bodied valve system. The interconnecting pipework seen in the picture is supplied separately. This unit can be purchased complete with the pipework or without. A duplex water softener will save on salt consumption and be more efficient than a simplex softener. It will also have a larger footprint, so are useful for plant rooms where floor space is not an issue.
Our systems are built by our team of senior engineers ensuring the reliability you require and come with a typical resin life expectancy of around 10 to 15 years. Metered Clack duplex softeners consist of all the required components to allow you to start softening your water straight away.
