Neutralizing Amine for Steam Boiler Condensate Treatment

The AQUAGUARD 200 Series is designed to protect condensate return systems from corrosion by neutralizing dissolved carbon dioxide and other acid contaminates. Carbon dioxide is generated by the breakdown of carbonates and bicarbonates dissolved in the feed water. The carbon dioxide is then readily dissolved in the water, resulting in the formation of carbonic acid.

AQUAGUARD 206 is a neutralizing amine designed to treat condensate in small steam boiler systems with short condensate runs. AQUAGUARD 206 features a low vapour to liquid distribution and will condense in the initial steam condensate to give early system neutralization and protection. It is best suited for small, well sealed systems.

For more complex systems, AQUAGUARD 211, 221 and 240 are specially formulated using a complex and proprietary blend of neutralizing amines.


  • Neutralizes dissolved carbon dioxide and other acid contaminates to provide cost effective condensate corrosion control.
  • Ideal for systems with short condensate runs.
  • Easy to use, test and control by monitoring the condensate pH.
  • Volatile to prevent corrosion throughout the steam condensate system.


AQUAGUARD 206 is a neutralizing amine with a low vapour to liquid distribution ratio suitable for systems with short condensate runs and low levels of make-up water. It will condense with the initial steam condensate in the front end of the steam system and give early system neutralization. It gives good protection in initial condensation areas and is best suited for small, “tight” systems.
