High Efficiency Mixed-Bed Resin
ProBlend™ NG-HE (P/N ER30001) — We took our ProSoft™ Premium softening resin and our ProSelect™ General Purpose anion exchange resin and mixed them together to make one of the highest capacity bulk demineralizers available. ProBlend™ Nuclear Grade High Efficiency Mixed-Bed Resin is specially suited for optimum performance and low cost regeneration. It is simply the best value for the dollar.
Portable Exchange D.I. (PEDI)
Potable Water
Demineralizer applications requiring high resistivity and low amine odor
ProBlend NG-HE 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.
ProBlend NG-HE Backwash Graph
BACKWASH — The backwash step is used to separate the components prior to regeneration and to remove particles. The separation is optimized at a bed expansion of 50 to 75 percent.
CAUTION: DO NOT MIX ION EXCHANGE RESINS WITH STRONG OXIDIZING AGENTS. Nitric acid and other strong oxidizing agents can cause explosive reactions when mixed with organic materials such as ion exchange resins.
