Call 01507 608100 For Price
20" Corrosion and scale inhibitor dosing cartridge designed to fit industry standard big blue housings. These cartridges dose the water with hexemeta polyphosphate which is a food grade (and approved) material which basically stops water from attacking metals and stops limescale bonding in plates.
The 20" models are commonly used in large industrial applications and as pre-treatment to systems such as UV to stop scale forming on the quartz tubes. They are also sometimes used post-RO to treat water which is excessively aggressive.
Cartridge life: Life proportional to usage and water flow
Designed to fit all regular 20" Big Blue Housings
