Condensate Polisher Size Calculator & Guide

How do you determine the correct size of a condensate polisher? The calculations below can be used as a size guide for condensate polisher units. Condensate polishers are ideal for power generation, boiler feeds, sugar production, thermal power plants, distilleries, food & beverage, and any critical applications where stainless steel (316L, 316, 304) is a requirement due to heat content in the water and where 0 ppm hardness is required. Stainless steel water softeners are also ideal for pharmaceutical, pharma water for injection (WFI), dairy, and many other ultra-pure water (UPW) applications.  Carbon filters, reverse osmosis systems, deionization (DI), DI exchange tanks, electrodeionization (EDI) systems, ultrapure water storage tanks, oxygen removal and carbon dioxide removal systems are used prior to the deaerator (DA) and boiler for optimal performance and efficiency.

If you need information about your water to complete the calculator, note that we offer free basic water testing to qualified engineers and industrial, commercial, and healthcare organizations. Other calculators for specialized industrial water softeners are here:

Many variables exist when sizing condensate polisher units for power generation and critical boiler applications that are beyond the scope of the condensate polisher calculator & guide below. Water pressure, temperature, flow rate and cubic feet of resin per tank are all variables that have effects on water softener sizing and are not considered. These guides are to be used for quick estimates for sizing, footprints & general design of condensate polishers.

For detailed condensate polisher sizing including configurations (e.g. single, twin parallel, twin alternating, triples, quad hot water softener polishers, mixed bed condensate polishing units), control types (time-clock, metered, Allen Bradley, GE, Siemens PLC, progressive flow, additive flow) or specific specifications like (316, 316L, 304) stainless steel or specific valve types & instruments, it is important that you email or call Industrial Water Solutions at 800-820-9021.
