This European-made anti-scale dosing system features a three-piece transparent and blue design with durable 3/4" BSP brass inserts and a pressure relief valve. It includes a proportional dosing mechanism using the Venturi effect to introduce polyphosphate into the water flow, reducing limescale formation in compliance with EU Directive 98/83/CE for drinking water.
Ideal for treating water with hardness up to 500 ppm, this high-quality housing ensures reliable, regulation-compliant scale prevention in residential and light commercial systems.
