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 0.14m³/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.
