RXSOL-50-5005-025 condensate is tested for PH to determine the dosage level. The PH limits are 8.3 - 9.0 . For an average system e. g. 10-M3, the dosage is approximately 0.65 ltr / day .
The necessary amount of RXSOL-50-5005-025 is required or injected as frequently as to maintain the pH of the condensate at the main condensate pump outlet between 8.6-9.5 . The amines pass over with the steam and have the dual function of elevating the pH of the steam/condensate and putting a protective micro film on the system pipe work. Acidic condensate is the result of carbonic acid (H2CO3) being formed as CO2 is released in the steam.Condensate prevents corrosion by carbonic acid on live systems. Its filming properties also reduce corrosion on shut down lines, when moisture and oxygen are present.
Not Compatible: Avoid copper, brass and aluminium.
Sampling and Testing
A representative condensate sample should be collected daily for analysis. The sample must always be taken from the same sampling point, cooled, and tested immediately. Testing should be carried out strictly in accordance with the test kit instructions, and all results must be recorded.
Condensate Control - Dosing Parameters (all pressure ranges)
The normal operating pH range is 8.5 to 9.2.
Measured pH
If the pH is below 8.5, increase the dosage by 25% and re-test after 24 hours, or sooner if required.
If the pH is within the range of 8.5 to 9.2, the system is under control and no dosage adjustment is required; continue routine monitoring.
If the pH is above 9.2, reduce the dosage by 25% and re-test after 24 hours, or sooner if required.
These values are recommended based on operational experience and are not intended to override boiler manufacturer guidelines or company operating procedures.
Regular testing is essential to ensure that treatment levels remain correct. Refer to the dosage chart to maintain the condensate pH within the target range of 8.5 to 9.2.
