Descaling liquid acid containing descaling accelerators, corrosion inhibitors and wetting agents.
Directions for Use and Dose Rates
The most effective descaling is accompilshed by circulation for large systems or components. In the case of small components, the soak method in an immersion bath can be used. If the equipment to be cleaned is contaminated by oil, grease , sludge or carbonized oil, then pre- cleaning with Tank cleaner or cleaner 517 is necessary. Descaling liquid should be mixed with fresh water to form a solution of 10-30% depending on the extent of scaling After using descaling liquid is essential to thoroughly rinse all metal surfaces at least once with a 0.5% solution of Alkalinity Control in fresh water. This will neutralize any remaining acidity and passivate steel surfaces.
Descaling liquid should not be used on aluminium, zinc,tin, or any galvanized surfaces for which a special grade cleaner should be used. Chemical cleaning module Delaran Rooz has developed a 280 litres capacity cleaning module primarily designed for use with chemical acid solvents for descaling boilers , calorifiers, heat exchangers and other types of equipment where rust and scale form.
Descaling boilers, diesel engines,cooling systems, condensers, evaporators ,calorifiers ,and Heat Exchangers- see Delaran Rooz practical application manual.
