The High Efficiency (HE) Twin softener with patented technology delivers improved efficiency to reduce operating costs. The HE Twin softener reduces hard water contaminants*, reducing scale build-up that affect equipment performance. The HE twin configuration consists of two independent mineral tanks, which provide a continuous flow of soft water 24 hours a day. With the Culligan® Smart Controller, available on the HE Twin, the softener adjusts to influent water conditions and regenerates based on need. Customers can also monitor their water treatment system performance, consumable usage, and maintenance needs, at a single site or across multiple ones 24 hours a day.
