Edge2Edge Flow: Total Resin Contact. Zero Compromise.
All Minimax softeners are built around Harvey’s advanced twin-cylinder technology, powered by a high-performance full-flow shuttle valve that keeps softened water flowing even during regeneration. That means no downtime, no pressure loss, and no compromise on comfort.
But what truly sets Minimax apart is our Edge2Edge Flow system - Harvey’s patented approach to resin bed performance.
This technology came from a bold move:
Harvey acquired the use of the worldwide patent for a unique top-and-bottom mesh system from US-based Hague, on the condition that Harvey stayed out of the American market. It was a gentleman’s agreement that changed the game here in the UK.
With Edge2Edge Flow, water enters from the bottom of the softener and travels upward, drenching the entire resin bed—from edge to edge, with no shortcuts. This completely eliminates channeling, a common problem in other softener systems where water finds the easiest route and leaves parts of the resin unused or over-saturated with chalk.
The result?
-
100% resin usage
-
Maximum contact time
-
No chalk left behind
-
Unrivalled softness, right to the last drop
It’s a system so precise, it performs flawlessly even at trickle flow rates, making it suitable for every UK plumbing system - from unvented hot water systems to combi boilers to gravity-fed loft tanks.
And because it adapts to your household’s flow patterns, it’s perfect whether you’re staying put or planning a move, and regardless of how much water you use.
