Steam Boiler Treatment

AQUAGUARD 841 FP utilizes an innovative formulation of film forming and volatile corrosion inhibitors, pH buffering agent, dispersants and cleaning agents to provide complete protection to the boiler and condensate system.

When AQUAGUARD 841 FP is first introduced into the system, it will begin to form a protective monomolecular film while simultaneously cleaning the system, removing existing foulants. AQUAGUARD 841 FP is designed for use in steam boiler systems with high makeup volumes and feed water pretreatment – such as those utilizing demineralized, RO, or softened makeup water.


  • Single product solution – fully formulated for complete system control.
  • Easy to use, monitor and control.
  • All organic treatment – does not contain molybdenum, nitrite, phosphate or sulphite.
  • Effectively treats the system feed water by buffering to the desired pH range to prevent corrosion.
  • CFIA approved for use in registered food plants – refer to LONO for full details.


AQUAGUARD 841 FP is ideal for use in large commercial, institutional and industrial steam boiler systems with high makeup water volumes. While AQUAGUARD 841 FP has a degree of tolerance for hardness leakage, optimal results are attained in systems utilizing effective feed water pre-treatment such as those utilizing demineralized, RO or softened makeup water.
