The SX2-11 is a single-housing water treatment system with a drop-in 10” cartridge. The system utilizes ScaleX2®, a chemical-free scale inhibition technology that utilizes Template-Induced Crystallization to effectively inhibit the formation of calcium-carbonate scale. The SX2-11 is ideal for applications requiring up to 1.5 gpm flow. In most cases, the cartridge will perform for one year between filter changes.
