General Information

The Fleck 9000 Duplex Water Softener Units are suitable for Commercial, industrial and residential applications. All of our systems are either Time Clock or meter controlled (please select from the drop down menu)

The benefit of a meter controlled system is that it allows the system to calculate your water usage and instigate a regeneration cycle only when you have consumed enough water for the resin bed to be exhausted. These systems prevent any unnecessary water wastage and also ensure that your resin bed is never running past the state of exhaustion.

Timer controlled softeners allow you to set a particular time for regeneration and are also consistent and reliable.

We supply Simplex, Duplex, Triplex and bespoke water softening systems.

Duplex softeners are designed to produce a continuous and uninterrupted supply of softened water 24/7. To achieve this, these systems have a twin tank that work alternately so that there can always be one tank in service while the other thank is regenerating. These systems are particularly useful for industrial or commercial applications where stopping production for the regeneration process is simply not possible.

What is a Simplex Water Softener?

A simplex water softener consists of one vessel containing ion exchange resin. Once the iron exchange resins are exhausted, the water softener will go into the regeneration sequence. During the regeneration sequence that takes about two hours, there will be no water passed through the softener to service. If the water softener is time controlled, it is possible to set the regeneration time to 3am when there is usually no requirement for water. If the water softener is a water meter controlled unit, it is more difficult to gage what time the water softener will regenerate. If a continuous supply of softened water is required, it is advisable to install a duplex water softener.

What is a Duplex Water Softener?

A duplex water softener consists of two vessels containing ion exchange resin, once the first column of resin has exhausted and goes into regeneration, the second column goes into service. This maintains soft water to service at all times. Duplex water softeners are usually water meter controlled but in some cases, duplex water softeners can be time clock controlled.
