RWC45 Series Water ConditionerSoftens and Filters

Whether you have municipal water that is hard or chlorinated, The Rain RWC45 water conditioners deliver the clear, soft, odor-free water you want and need. Its environmentally-friendly tank design eliminates the need for two systems by combining two medias into one tank. The activated carbon reduces chlorine and other unwanted tastes while the high capacity resin softens the water.

The Meter
Water usage is electronically monitored and the system automatically regenerated based on actual water consumption. The controller can anticipate higher water usage based on previous trends and regenerate the system in advance, as needed, to ensure the availability of quality water. Likewise, when water usage is low, the system regenerates less often, saving on salt and water.

The Electronics

The microprocessor captures all water conditioner operations, including gallons per day, total gallons, peak flow rates, and total regenerations. Time is also held in memory and protected by a built-in battery backup.

Optional Weather Cover A weather cover ideal for outdoor installations and is available on the Rain Water Conditioner RWC45 model.

Only the Rain RWC 45 features a top tank flange for easy servicing as well as a LED display.

The Rain RWC45’s unique “mid-plate” tank design is efficient and performs like two units, accommodating activated carbon and high capacity resin in one tank. The carbon also protects the resin from highly chlorinated water— avoiding unnecessary mineral replacement, saving you time, money, and energy.

  • Carbon: Reduce unwanted chlorine and its odors
  • Resin: Eliminates hardness and stops energy drain in water heaters
