- Max softening capacity for this system depends on the cubic feet of resin the system is built with. For ease of comparison, a 1.0 cubic foot resin volume is assumed on this chart.
† The resin volume for these systems is variable (1.0, 1.5, 2.0, etc). For ease of comparison to other systems, a 1.0 cubic foot resin volume is assumed on this chart.
†† This is a twin tank system, so each tank contains the same amount of resin.
‡ The max service flow rate is a function of the resin volume used to build the system. For ease of comparison to other systems, a 1.0 cubic foot resin volume is assumed on this chart.
