Twin Alternating

AMI Twin Alternating Water Softeners for Whole House, Commercial, and Pretreatment Applications

Twin softeners are ideal for situations where uninterrupted flow of soft water is a must. One resin tank is always in service, while the other tank is in standby. When the meter determines that the resin is near its capacity, it will switch the tank in standby to be in service, and the tank containing the exhausted resin will begin regeneration and wait in standby until the other tank is ready for regeneration. 

Hard Water contains dissolved minerals in the form of Calcium (Ca), Magnesium (Mg), and Iron (Fe). Removal of these minerals is accomplished by softening the water through an ion exchange process using a water softener. As the water flows through the mineral tank of the water softener, the dissolved minerals become attached to the resin, creating soft water. Over a period of time the resin in the water softener will become exhausted, and the water softener will regenerate using a brine solution produced from the salt in the brine tank.

Benefits of Using a Twin Alternating Water Softener

  • Uninterrupted Flow of Soft Water
  • Higher Quality Drinking Water
  • Prevents Hard Water Scale
  • Prevents Staining on Bathroom & Kitchen Fixtures as well as Dishes, Dishwasher, Washing Machine and Clothes
  • Significantly Reduces Soap and Cleaning Product Consumption
  • Provides Excellent Grooming & Cosmetic Benefits
  • Reduces Water Heating Costs
  • Prolongs the Life of Water Heaters, Icemakers, Dishwashers, Coffeemakers, Plumbing Fixtures, and All Downstream Equipment.
  • Use as Pretreatment to Reverse Osmosis will Prevent Membrane Scaling and Prolong Membrane Life

Ordering Notes:

  • Softeners are available with USA or European style plugs and voltages. Please add the appropriate voltage code to the end of the model when ordering.
    • 120V AC/60Hz with USA cord = US
    • Example: W-S744ETS-US
    • European 220V AC = EU (EU plug is removable to convert into universal 220v cord)
  • 5 gpm per sq. ft. of media is the best design condition for filtration. For relatively clean water, you may go up to design criteria of 15 gpm per sq. ft. Backwash flow rate based on 25 psi pressure drop.
  • Skid mounting, control panel and custom sizes and configurations are available upon request. AMI Water Softeners are offered standard with new state of the art electronic programmable valves, but may be ordered with electromechanical Fleck valve heads upon request.
