Condensate Treatment Chemical


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.
