The FXTS-12 is a single-housing water treatment system with a drop-in 20” cartridge that protects equipment against damaging scale (lime scale) and takes out dirt and sediment down to 5-microns. The system includes IsoNet®, OptiPure’s patented scale inhibiting technology, which delivers consistent protection against the precipitation and accumulation of scale, and provides a protective barrier to help guard against corrosion.
