Amines are used to increase the condensate pH for your boiler water and steam boiler. A low condensate pH will result in excessive condensate pipe corrosion and steam leaks. This condition may require premature condensate pipe replacement.
High make-up water and/or low feedwater temperatures will lead to lower condensate pH. In general, the condensate pH should be maintained between 7.8 and 8.2.
The 3 most common amines for Steam Treatment are Cyclohexylamine, Morpholine, and Diethylhydroxylamine (DEAE).
* Cyclohexylamine is used for extensive condensate pipe system and has the highest impact on pH.
* Morpholine is excellent for steam short condensate pipe runs and has the lowest impact on condensate pH.
* Diethylhydroxylamine is a general purpose amine for use in low to medium pressure boilers.
It is common in industry to order a blend of all 3 Amines, although not required. These are referred to "Tri-Blend" Amines.
Steam Treatment 1688
ST1688 is a concentrated blend of three neutralizing amines Cyclohexylamine, Morpholine, and Diethylhydroxylamine (DEAE).
