Fleck Simplex 3900

Simplex valves are available in both Time clock or meter controlled.
Time clock systems are ideal for applications that do not require 24/7 soft water. The timer can be manually set to initiate regeneration at a time where soft water is least likely to be required.

Timers are usually automatically set to regenerate at 1am. Whilst the system undergoes the regeneration process, a bypass valve will allow for hard water to be available.

Meter controlled systems are more technically advanced. They calculate the permeate flow and from that, determine when to initiate the regeneration process according to your pre entered specifications. Once the permeate flow has hit the predetermined threshold, the regeneration cycle will ensue triggering the bypass valve. Once the system is in the regeneration cycle, hard water will be made available.

If you require soft water 24/7 then a Duplex system is required. A duplex water softener system features two columns, once one system goes into regeneration, the next system comes into service.
