Softening Resin ProSoft™ Gold
ProSoft™ Gold (P/N ER10001) — SWT found a great way to save you some money and still get the job done. ProSoft™ Gold is a 7% crosslinked softening resin that is designed for low or non-chlorinated waters. It is perfect for well water and non-turbulator applications. It has excellent exchange capability and every bag is pre-washed and rinsed so that you don't have to do it in the field.
ProSoft™ Gold is ideally suited for use in industrial, commercial, and residential softening applications where free chlorine is not present because of its high capacity, uniform particle size, and good physical stability.
ER10001 Pressure Drop Graph
PRESSURE DROP — The graph above shows the expected pressure loss per foot of bed depth as a function of flow rate at various temperatures.
ER10001 Backwash Graph
BACKWASH — After each cycle the resin bed should be backwashed at a rate that expands the bed 50 to 75 percent. This will remove any foreign matter and reclassify the bed. The graph above shows the expansion characteristics of ProSoft™ Gold in the sodium form.
