The SX2-12TWH is a single housing water treatment system with a drop in 4.5” x 20” 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 SX2-12TWH is ideal for applications requiring up to 6.0 gpm continuous flow or 10.0 gpm peak flow. In most cases, the cartridge will perform for one-year between filter changes.
