Nelsen Water Solutions C-Series

Nelsen Water Solutions C-Series Softeners

The C-Series control valve has been engineered to provide years of trouble-free service. The key to the exceptional quality of the C-Series control valve is in the state-of-art design. The C-Series valve is one of the most advanced controls available in a variety of configurations including a solar powered control.

Where space is a concern, C-Series Cabinet systems fit right in. It combines the entire system, softening tank and salt storage into one compact unit. It can even be placed in a closet, convenient for loading salt but out of sight. Don’t let the compact design of the C-Series Cabinet fool you. It will provide you with soft, iron-free water for years to come.


Benefits of a Nelsen Water Solutions System

In the Bathroom

Your soap and shampoo will lather better. Your hair and skin will feel noticeably cleaner, softer and not as dry. Additionally, there will be no soap scum or mineral deposits to clean off sinks, showers, tubs, and toilets.

In the Kitchen

Dishes will clean up more easily and be spot-free, without the gray film glass gets when etched by mineral-laden wear. Plus, hands will feel softer and look better.

In the Laundry

Clothes will be softer, cleaner, and brighter and last longer. Using soft water and pure soap products increases the life of clothing, towels, and linens by up to 33%. Without hard water service issues, washing machines will last longer, too.

Plumbing and Appliances

Appliances that use water will last longer and run better. Why? Because water heaters, washing machines, and dishwashers using hard water can wear out 30% faster.
