Opti-Brining® for sustainable softening

Opti-Brining® is Monarch Water’s unique, new system to manage water within its next generation of HE water softeners.

TheintelligentOpti-Brining® component continuously monitors the softener’s activity and water usage, regenerating only when necessary, to save more water, salt and energy than previous generations.

Opti-Brining® technology offers higher exchange capacity, higher flow rates and reduced water consumption during regeneration. With up to 46% greater capacity per regeneration than previous units for a truly sustainable future.


Hi-Flow Rapid-Fit bypass for easy installation

The NEW HE range of water softeners all feature Monarch Water’s NEW Rapid-Fit bypass which has reduced 85% of the components needed when installing a water softener.

Available for 15mm, 22mm and 28mm supplies, the Rapid-Fit also has 3/8” connections for both hard and soft water tee points. It also features a 1” high flow check valve built into the body to comply with WRAS guidelines, giving an impressive flow rate of 80lpm.

With Monarch Water’s NEW Rapid-Fit bypass, installers simply connect the water in and out from the mains supply, then connect two hoses to the softener for quick and easy installation.



Next Generation

Digital interface and operating system for ease of use.
