Technical specifications
FIPRO AK 962 is a powder product based on inhibited organic acid that is used for cleaning circuits soiled mainly by deposits containing lime and iron oxides.
Usage and Applications
FIPRO AK 962 is a product for industrial use only and is used for iron, cast iron, stainless steel, aluminium, copper, brass and galvanised sheet metal.

Power supply
FIPRO AK 962 should be used diluted to a concentration of 5 to 10%, depending on the degree of fouling of the system, and should be added while the system is stopped. The following are necessary for good cleaning:
18 - 24 hours with a solution temperature of 20-30 °C
10 - 12 hours with a solution temperature of 50-60 °C
After descaling, the circuit must be drained and rinsed.
After the rinsing phase, we recommend the use of an appropriate passivating agent (FIPRO AK 955) to form a protective film on the walls. During the cleaning phase, the colour of the acidic attack solution should be observed. When the colour 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 the solution will be titrated with Sodium Hydroxide (NaOH) 1N, in the presence of Methyl orange indicator until it turns from red to yellow. The number of ml of NaOH 1N consumed, multiplied by 4.2 expresses the concentration of FIPRO AK 962 still active. It is recommended to contact Fiprokim Technical Service for special operational requirements.
