3M™ SF18-S scale reduction system with stainless steel tee head inhibits scale build-up and corrosion in high-temperature foodservice equipment, including coffee brewers, broiler-based steamers, proofers, warewashers and hot tea. A proportioning forced-feed-orifice delivers a carefully metered amount of a unique high-temperature scale inhibitor, sequestering the hardness minerals that form on boiler walls, sensors, brewer spray heads and heating coils. The media does not break down at temperatures at or above 200°F (93.3°C). The Sanitary Quick Change (SQC) replacement HF18-S cartridge makes change-outs fast and easy. Replacement: HF8-S, part number 5582106.
