Steam Boiler Treatment

AQUAGUARD 432 is a concentrated liquid steam boiler treatment chemical designed to control scale and sludge, maintain alkalinity in the boiler, remove oxygen from the feed water, and control corrosion in the condensate system.

AQUAGUARD 432 is a synergistic blend of scale inhibitors, alkalinity boosters, catalyzed oxygen scavenger, and volatile amine.

AQUAGUARD 432 is not meant to be used in hot water boilers or any other type of heat exchange equipment other than steam boilers.


  • Single component steam boiler-water treatment: scale control, alkalinity control, dissolved oxygen control, condensate corrosion control.
  • Scale and corrosion control to maintain clean heat transfer surfaces in the boiler
  • Easy to use and control
  • Effective in hard or soft water areas


AQUAGUARD 432 is ideal for a variety of commercial, institutional and small industry systems. If your feed water is softened, consider AQUAGUARD 433 for your treatment needs.
