Duplex water softeners supply soft water 24hrs a day, with no interruptions, with regenerations directly linked to the amount of water used, there is no ‘outage’ time for hard water, and salt use is kept to a minimum.

A traditional commercial single tank softener has to be considerably larger than actually required to accommodate peak water demand. When a single tank softener regenerates, it can only provide hard water during the regeneration, whereas, the Duplex unit would simply switch to the standby softener to ensure a continuous supply of soft water.

Operation
Duplex softeners have two softening vessels sharing the same salt tank. These two vessels are connected by a single control valve with a built in water meter.

One vessel supplies soft water whilst the other remains on standby. When the required amount of soft water has been reached this vessel begins an automatic regeneration with soft water then supplied from the previous standby vessel. This role is then reversed when the next regeneration is due. This way there is a continuous supply of soft water at all times.

With our Duplex softeners using a wet brine system, the regenerations can be more frequent ensuring an even greater output of soft water from a smaller softener. The only maintenance necessary is to ensure the salt tank is kept full of tablet salt.
