The Monarch HW70/15 Hot Water Pro-Flo Automatic Water Softener is a professional-grade water treatment system designed for commercial kitchens and hospitality environments where hot water feed systems are in operation.
With a capacity of 2,850 litres (at 300ppm hardness), this model is ideal for medium to large commercial operations such as restaurants, hotels, pubs, and catering facilities. It ensures a continuous supply of softened water to protect dishwashers, glasswashers, boilers, and other hot water-fed equipment from damaging limescale build-up.
This unit is specifically engineered to operate at temperatures of up to 70°C, making it suitable for demanding warewashing systems where standard softeners would fail or degrade. Its hot water-rated construction ensures consistent performance and reliability in high-temperature environments.
The system uses advanced ion-exchange technology to remove calcium and magnesium ions, improving cleaning efficiency, reducing maintenance costs, and extending equipment lifespan. As part of the Pro-Flo range, it features automatic, timed regeneration with user-friendly control for efficient operation.
A key benefit of the HW70 series is its standardised footprint across the range, making it easy to upgrade or scale systems without redesigning installation space. It also includes an optional hot water bypass, ensuring uninterrupted water supply during maintenance or regeneration cycles.
Built for commercial durability, the unit is WRAS compliant and supplied with installation accessories including drain and air gap protection, supporting safe and compliant installation in professional environments.
