it’s important to have the hard facts: hardness and minerals in water cost businesses millions of dollars annually in plumbing repairs, energy consumption, premature replacement of equipment and fixtures, replacement of linens, clothing, towels and other laundry and maintenance. Using ion exchange, remove harsh calcium, magnesium, iron, and manganese ions from your water supply. In the end, businesses run more effectively by using less detergent, reducing hard-water build-up and saving equipment from unnecessary wear.
