ScaleAwayHCA concentrate is a highly active descaler and cleaning agent based on hydrochloric
ScaleAwayHCA concentrate can be used to dissolve lime-scale (calcium carbonate) deposits
in boilers, calorifiers and heat exchangers. NOTE - ScaleAwayHCA concentrate should NOT be
used on stainless steel, aluminium or galvanised surfaces.
Application rates for ScaleAwayHCA concentrate can be used at strengths between 10 and 50% and
at temperatures up to 80°C, the speed of reaction being enhanced by acid strength and elevated
temperature. Contact ScaleAway for the exact dosage recommended for a particular application.
ScaleAwayHCA concentrate is a solution of hydrogen chloride (HCl) in water, that is a highly corrosive, strong mineral acid with
many industrial uses. It is found naturally in gastric acid.
Concentrated hydrochloric acid (fuming hydrochloric acid) forms acidic mists. Both the mist and the solution have a
corrosive effect on human tissue, with the potential to damage respiratory organs, eyes, skin, and intestines.
Personal protective equipment such as rubber or PVC gloves, protective eye goggles, and chemical-resistant clothing and
shoes are used to minimize risks when handling hydrochloric acid.
Completion of descaling should be determined by either testing acidity or pH periodically. When
descaling is complete acidity or pH should be constant. If solution shows no acidity or pH
rises to 4 or higher then more ScaleAwayHCA concentrate solution should be added.
After completion of descaling, equipment should be drained and flushed thoroughly with water.
The management of waterscale, limescale and rust from the waterside of your equipment and
associated piping is of paramount importance for the efficiency of your equipment.
