SECTION C – SCALEBREAKER CHEMICALS

INTRODUCTION

The prepared chemical solutions may be used to soak the equipment to be descaled, although the process is
significantly faster when the solution is circulated vigorously by means of a suitable pump such as a Scalebreaker
descaling pump.
During descaling limescale dissolves with the evolution of gas. The resulting effervescence and foaming can create a
barrier which impedes, and in some case prevents, further reaction with the deposits. Agitation of the solution or the
use of a Scalebreaker pump will break down this barrier allowing further reaction to take place.
General usage and application notes
As a general guide, the rate at which deposits are dissolved increases with solution strength and higher temperatures.
Lower chemical concentrations will require a higher water temperature for best effect.
Pumps and chemicals should not be operated at temperatures exceeding 50°C.
As chemicals increase in strength so does the limitation in their use. Stronger chemicals should not be used on certain
materials and so it is essential to know what the item to be descaled is made of, to enable the appropriate chemical
selection. Kamco descaling chemicals are either in crystalline or liquid form.
Crystals should be dissolved in water prior to adding to the Scalebreaker tank.
Relative strengths of chemicals, in ascending order:
Scalebreaker CG crystals.
Scalebreaker SR crystals.
Scalebreaker FX liquid.
Scalebreaker HD liquid.
Strength indicator
Stronger chemicals incorporate a red to yellow pH colour change indicator to give a visual check on solution strength.
As the solution strength is exhausted the colour changes from pink, through amber to yellow. Further descaling
chemical can be added to return the solution back to full strength.
Inhibited
Stronger chemicals are comprehensively inhibited to help protect metal surfaces during the descaling process.
Safety.
Suitable precautions should be taken when handling any chemicals especially acids.
Avoid contact with eyes and skin. Wear protective clothing, gloves and goggles.
When descaling with any acid, there is a possibility of flammable hydrogen gas being given evolved, and the working
area should be well ventilated. Avoid smoking nearby, or any other means of ignition.
Always add the descaling chemical to the water to avoid a reaction.
Transport regulations
Due to the hazardous nature of these chemicals some transport restrictions may apply, especially to Scalebreaker HD.
Please call for advice. All goods are available for collection.
Material Safety Data Sheets (MSDS).
The latest Material Safety Data Sheets are available to download from the Kamco website.
These sheets include: chemical composition, hazard classification, first aid measures, handling, storage and disposal
information.
