Description
The Nu-Calgon 9606-51 4SI Cartridge inhibits scale buildup and controls sediment deposition in ice machines and water-intensive equipment. Installed inline into compatible water filter housings upstream of HVAC systems, the replacement cartridge filters incoming water through internal treatment media. The polyphosphate and filtration media trap particulate matter while sequestering hardness minerals such as calcium and magnesium before they can dissolve out of solution. Preventing scale formation keeps internal water lines clear preserves heat exchange efficiency and supports steady equipment operation.
