Commercial Water Softener Sizing Calculator & Guide (FRP) for Fleck and Clack Water Softeners

How do you size a Fleck commercial water softener or a Clack commercial water softener? See our full list of commercial water softener sizing calculators and guides or use the calculator below. The following calculations can be used as rough guides for icommercial, top mount valve water softener sizing.

See our helpful industrial water technical articles and resources along with our industrial water softeners information. If you have a unique application such as hot water, special construction materials, high efficiency or industry specific, please call us or see some of the specialized water softener calculators below:

Fleck Commercial Water Softener Sizing Guide & Calculator (Fiberglass – FRP – Clack)

Average Gallons Per Day (GPD) Flow Rate:
Peak Continuous Flow Rate GPM*:
Desired Hours Between Regenerations:
Hardness of Water (Grains Per Gallon):
Capacity per Cubic foot of Resin (Grains):
Total Gallons of Water Used Between Regenerations:
Cubic Feet of Water Softener Resin Needed Per Tank:
Inch Valves (estimate):

Many variables exist when sizing Fleck commercial water softeners beyond the scope of the fiberglass (FRP – Fleck/Clack) top-mount valve water softener calculator below. Water pressure, temperature, flow rate and cubic feet of resin per tank are all variables that also have effects on water softener sizing and are not considered. These guides are to be used for quick estimates.

For detailed commercial water softener sizing including configurations (e.g. single, twin parallel, twin alternating, triples, quad softeners), control types (time-clock, metered, PLC, progressive flow, additive flow) or pretreatment for reverse osmosis, deionization or other ultra high purity water treatment equipment, it is important that you email or call Industrial Water Solutions at 800-820-9021.
