Power supply
FIPRO AK 962 should be used diluted at a concentration of 5 to 10%, depending on the level of system contamination, and should be added while the system is shut down. For thorough cleaning, the following are required:
18 - 24 hours with a solution temperature of 20-30 °C
10 - 12 hours with a solution temperature of 50-60 °C
Once descaling is complete, the circuit must be drained and rinsed.
After the rinsing phase, the use of an appropriate passivating agent (FIPRO AK 955) is suggested in order to form a protective film on the walls. During the cleaning phase, the color of the acidic etching solution must be observed. When the color changes from red to yellow-brown, the descaling effect is exhausted and the product must be replaced with a fresh solution.
The concentration of FIPRO AK 962 in the solution can be checked by titration.
A 10 ml sample of solution will be titrated with 1N Sodium hydroxide (NaOH), in the presence of Methyl Orange indicator until the color changes from red to yellow. The number of ml of 1N NaOH consumed, multiplied by 4.2, expresses the concentration of FIPRO AK 962 still active. It is recommended to contact the Fiprokim Technical Service for specific operational requirements.
