The Monarch HW70/30 Hot Water Pro-Flo Automatic Water Softener is the largest model in the HW70 range, engineered for demanding commercial environments where high-volume water usage and hot water systems require continuous protection from limescale.
With a capacity of 5,700 litres (at 300ppm hardness), this system is designed for large restaurants, hotels, catering facilities, and institutional kitchens. It provides a consistent supply of softened water to protect dishwashers, glasswashers, boilers, combi ovens, and other hot water-fed equipment from scale build-up that can reduce efficiency and increase maintenance costs.
As part of the Pro-Flo HW70 series, this model is specifically built to operate at temperatures of up to 70°C, making it suitable for hot water warewashing systems where standard softeners would fail or degrade. This ensures reliable performance in high-temperature environments commonly found in professional kitchens.
The system uses advanced ion-exchange technology to remove calcium and magnesium ions from the water supply, significantly reducing limescale formation. This improves cleaning performance, reduces energy consumption, and extends the lifespan of connected equipment.
It features fully automatic, timed regeneration with a high-efficiency resin system designed to optimise salt usage while maintaining consistent output. The HW70 range also shares a standardised footprint across models, making installation and upgrades straightforward without requiring system redesign.
A key benefit is the optional hot water bypass, allowing uninterrupted water supply during regeneration or maintenance. The unit is WRAS compliant and supplied with commercial-grade installation accessories for safe and reliable setup.
