The Purolite Duplex Water Softener Units are suitable for both commercial and large residential applications. The system uses a 1" Clack Time Clock Softener Valve which undertakes a regeneration cycle whenever it is programmed to do so. Upgrading to a Metered Valve is available which will regenerate according to water usage and the hardness setting programmed into the valve.

Purolite 75L Duplex Water Softener 13 x 54 Inch 50 LPM

Duplex softeners are designed to supply softened water in situations where a continuous and uninterrupted supply of softened water is required. These systems therefore have a twin tank, so that there can always be one tank in service while the other thank is running a regeneration back wash or on standby, thereby guaranteeing a 24/7 soft water production.

Our range of Duplex Water Softeners use high grade Purolite C100E Cation Softener Ion-Exchange Softener Resin, NSF certified Minerals Tanks and the world's most reliable and well-established softener valve on the market today, made in the USA the Clack Valve, so you can ensure you are only buying top quality, reliable and cost effective equipment.

How often do the filters and resin need to be changed, also does it come with all the installation components needed, thankyou.
Question by: Aureljo on 7 May 2021, 18:49
Resin normally will last for 10-15 years. To protect the resin from premature depletion it is best to install a filtration system before the softener. Chlorine is the main cause of premature damage to the softening resin.
