 | Heating system cleaner K 40
for all hot water heating systems
Sotin K 40 gently cleans and removes rust sludge, hardness deposits and installation residues from hot water heating systems, even during operation.
Sotin K 40 is suitable for all materials commonly used and approved for heating engineering (including plastic materials). Corrosion and hardness deposits are removed in finely distributed form. Surfaces in contact with water are prepared for the subsequent protective treatment using Sotin K 20 heating system protection.
Dosing quantity: approx. 1.5 litres of Sotin K 40 for 200 litres of heating water. Usage time: max. 8 days, 40°C to 60°C water temperature
