Sizing Guide for Industrial Water Softeners

Calculate the correct size for your industrial water softener below using these free online calculators. The calculations can give you approximate sizing for industrial water softeners. If you need to size hospital water softeners or hotel water softeners, please see these specialized water softener calculators:

General Industrial Water Softener Sizing Calculator and Guide

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):

There are many variables in sizing industrial water softeners beyond the scope of the water softener calculator below such as water pressure, temperature, flow rate and cubic feet of resin per tank. These are all variables that also have effects on water softener sizing and are not considered here, as these guides are to be used for quick estimates only. We recommend that you choose the option for Nancrede Engineering to follow up with you to work through your specific industrial water softener requirements.

For detailed industrial water softener sizing including configurations (e.g. single, twin parallel, twin alternating, triples, quad softeners), control types (timeclock, 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 Nancrede Engineering at 888-569-2837. Our engineers are the same people you get in the field when there is an issue or when you call our free, unlimited technical support. Contact us right now, and we’ll find the perfect system that will save you energy and salt.

How much does it cost to operate an industrial water softener? See our industrial water softener operating cost calculator.

Nancrede Engineering also offers preventative maintenance, engineering consultation, equipment leasing, financing, and build, own, operate options. Let us know if you would like information on how these services can help you reduce downtime and capital risks.

* Peak Continuous GPM is not instantaneous peak flow rate. It represents a continuous high flow rate at peak times of the day (e.g. for 30 minutes or more).

** Instantaneous peak flow rate is the maximum GPM for a short time (e.g. 1-5 minute period).
