Liquitech D3 descaler is an acidic, super-concentrated solution based on a complex recipe that contains corrosion inhibitors and antifoams.
The product is intended exclusively for professionals.


It is used for cleaning thermal installations and heat exchangers in heating systems consisting of elements of Stainless Steel, Aluminum, Steel, Cast Iron, Copper, Iron. The product successfully removes deposits of limestone, rust and sludge without attacking the rubber seals present in the installation.
CAUTION !: Do not use on items that contain Zinc or Zinc alloys! The product is used together with a cleaning pump.



Step 1: Dose the product in a concentration of 10-20% depending on the degree of dirt present.
Step 2: Use the cleaning pump to start the chemical washing process of each circuit / radiator (recommended time: 20 min for each radiator / circuit). The descaling process is faster if the water is heated between 40 ° C - 60 ° C. It is recommended that the water temperature does not exceed 65 ° C so as not to damage the components of the cleaning pump.
Step 3: Monitor the pH value of the solution in the wash pump frequently, both with a pH indicator paper and visually. The pH should be <3, and visually the solution should be red. If the color changes from red to yellow-orange or if it completely fades and there are still deposits in the installation, add a new descaling pump in a concentration of 10% and continue washing until the deposits are removed.
Step 4: After descaling, rinse well with water
Step 5: Charge the cleaning pump with Liquitech Alkaline Neutralizer in a concentration of 5% and recirculate for 10 min.
Step 6: Rinse with water until pH 7-8 is reached
