clack ws2 metered simplex water softeners

Clack WS2 Simplex Water Softener

A Clack WS2 simplex softener is ideal for larger commercial and small to medium industrial applications like manufacturing plants that have downtime overnight. The system will use a single vessel with premium softener resin to give a large volume capacity of soft water over the course of the day. Peak flow rates on these units are between 10m3/hr and 26m3/hr.

These simplex units will usually be sized to regenerate every 1-2 days and take up considerably less room than a duplex unit, so are perfect for smaller plant rooms.

The Clack WS2 meter controlled systems are more technically advanced as they calculate the amount of soft water that has been processed and determine when to initiate a regeneration process according to Wateq’s pre-calculated settings.

We can tailor the regeneration process so that this can occur during low periods of water usage, this ensures that there is never an interruption to the supply of water. These systems are ideal for situations that do not require soft water 24/7.

WS2 simplex systems have a large footprint, so may not always be the best option. Alternatively you can use a smaller duplex softener if you require a lower flow rate, but constant capacity and soft water. Please see our duplex systems for more options.
