The Aquabion S15 is a 15mm in-line water conditioner designed to reduce limescale formation on pipework, cylinders, and appliances. It works on a physical conditioning principle rather than chemical or salt-based softening, so there's no salt to top up, no electrical supply needed, and no waste water produced during operation.||At just 120mm in length and 30mm in diameter, the S15 is compact enough to fit into tight spaces where a full softener wouldn't be practical, making it a straightforward retrofit on existing pipework. It's rated to handle a flow rate of 0.14m�/hr and a maximum working pressure of 16 bar, covering typical mains pressure applications.||Backed by a 1 year satisfaction guarantee, the S15 is a low-maintenance option for installers looking to offer limescale protection without the ongoing servicing, salt costs, or plumbing complexity that traditional softeners require.
