With a mineral resin capacity of 50 L, the RWS 50 control mechanism and automatic regeneration, it helps protect your plumbing, water heaters, washing machines and dishwashers from the harmful effects of hard water.
Ion exchange softening
By reducing hardness caused by calcium and magnesium, it keeps limescale formation under control and helps appliances run more efficiently and last longer.
Automatic regeneration
When the resin bed reaches saturation, the system automatically manages the regeneration cycle, aiming for uninterrupted performance.
Compact single-tank design
With a 10” x 54” FRP tank and a 100 L salt tank, it offers balanced capacity for home and small business installations.
Safe operating range
With an operating pressure of 2–6 bar and a test pressure of 9 bar, it is compatible with plumbing conditions and provides reliable use.
Highlights
Smart monitoring
System status and salt level are monitored, and maintenance notifications are sent.

Product description
Hard water leaves limescale in plumbing and in every appliance that uses water; over time it narrows pipes and reduces the efficiency of boilers and machines. The Rainwater RWS 50 is a water softening system that reduces the hardness of the water entering a building or facility using the ion exchange method.
Who is the Rainwater RWS 50 for?
For homes and small businesses. It offers a single FRP tank (10” × 54”), 50 L of mineral resin and a maximum service flow rate of 2 m³ per hour.
How does it work?
As water passes through the resin-filled tank, calcium and magnesium ions are retained by the resin, and the softened water flows on into the plumbing. When the resin is saturated, the system automatically recharges itself with the brine from the salt tank (regeneration), then backwashes and rinses.
What does it offer in daily use?
- Reduced limescale formation in plumbing and equipment
- Helps protect boilers, water heaters, washing machines and dishwashers
- Automatic regeneration; minimal user intervention
- 100 L salt tank, 2–6 bar operating pressure
Installation and maintenance
The system is installed at the water inlet of the building or facility, with the right capacity selected for the need. If required, it can be completed modularly with sediment, carbon and UV filters. Contact us for capacity selection, installation and maintenance.

Frequently asked questions
What does the Rainwater RWS 50 do?
It reduces water hardness caused by calcium and magnesium using the ion exchange method, helping to prevent limescale build-up in plumbing and equipment.
What is the capacity of the Rainwater RWS 50?
It offers 50 L of mineral resin and a maximum service flow rate of 2 m³ per hour.
Does water softening make the water salty?
No. Salt is used only to recharge the resin and is discharged to the drain during regeneration; the water does not become salty.
