Cuno (Aqua-Pure) SF165 Scale Guard HT (56186-01) 56246-01

Cuno Aqua-Pure ScaleGard HT provides consistent Recipe Quality Water with
reduced sediment and chlorine taste and odor. Operating cost savings from
the controlled and metered addition of scale-inhibitors reduces the ability of
calcium and magnesium to precipitate as hard scale in both high and lowtemperature
applications, including ice machines, coffee, tea, espresso
brewers, and steamers.

  • ScaleGard HT, SF165 combines chlorine taste and odor reduction with
    sediment reduction, and protection from the harmful effects of scale
    formation at flow rates to 3.34 gpm (12.6 lpm) for 35,000 gallons
    (132,000 liters)


  • Reduced sediment and chlorine for equipment protection and great
    tasting hot and cold beverages and ice.
  • A forced-feed orifice carefully controls and meters the addition of a
    proprietary scale inhibitor to reduce scale build-up on evaporator plates
    and heating coils.
  • Unmatched scale reduction performance in equipment from ice mahines
    to equipment heating water to temperatures over 200F (93C).
    (not tested or certified by NSF)
  • Revolutionary dual-zone Integrated Membrane Pre-Activated Carbon
    Technology ("IMPACT") filtration media combines a membrane in series
    with premium activated carbon to provide superior throughput and
    cartridge life.
  • Certified by NSF to Standard 42 for Class 1 sediment reduction and
    chlorine taste and odor reduction.
  • SQC - Sanitary Quick Change - encapsulated water cartridge design
    allows for fast and easy change-outs with a 1/4 turn while minimizing the
