The Monarch CS300 HE Pro-Flo Automatic Water Softener is a high-performance commercial water treatment system designed for demanding hospitality and foodservice environments where continuous water usage and reliable limescale protection are essential.
With a substantial daily capacity of 5,500 litres (at 300ppm hardness), the CS300 is the largest model in the Pro-Flo HE range, making it ideal for large restaurants, hotels, catering facilities, and institutional kitchens. It provides softened water to multiple appliances including dishwashers, glasswashers, combi ovens, coffee machines, and boilers, helping to maintain efficiency and extend equipment lifespan.
The system uses advanced ion-exchange technology to remove calcium and magnesium ions responsible for scale formation. This significantly reduces limescale build-up, improves wash performance, and lowers maintenance costs across all connected equipment.
As part of the Pro-Flo HE range, the CS300 features fully automatic operation with intelligent electronic control, volume-based regeneration, and optimised salt usage. Its high-efficiency design ensures consistent performance even under heavy demand, while the integrated bypass allows continuous water supply during regeneration cycles.
Built for commercial reliability, the unit is WRAS approved and designed with a robust, space-efficient footprint shared across the Pro-Flo range. It operates at temperatures up to 49°C, making it suitable for a wide range of professional kitchen applications.
