Descale Powder

Powder scale remover designed for use in the chemical cleaning of evaporators, boilers, cooling towers, heat exchangers, tanks and pipes, which are commonly fouled by hard water scales, grease, tarts and other impurities.

RXSOL DESCALE contains corrosion inhibitor which provides corrosion protection even after the cleaning, unlike other acid cleaning chemicals which may increase corrosion rate after cleaning. Moreover, it contains pH indicator which facilitate monitoring of cleaning progress.

 

Directions for Use and Dose Rates
The most effective descaling is accomplished by circulation. 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 and sludge, then pre-cleaning with RXSOL NEW org Plus or Enviro Degreaser. Depending on the extent of scaling, use a solution of 2.5-10% Descale Powder. The solution will have a red colour which disappear when the solution is neutralised. Whenever possible, the solution should be heated to 60°C. Neutralised solutions can be reactivated by adding more Descale Powder until the red colour reappears. This should not be done more than twice. Descale Powder should not be used on aluminium, zinc, tin or galvanised surfaces. Descaling of Boilers, Descaling of Diesel Engine Cooling Water Systems, Condensers,

Evaporators, Calorifiers, Heat Exchangers:
The strength of the acid can be enhanced by adding 1 part sodium chloride (common salt) to 20 parts of Descale Powder. This enhancement of the cleaning solution, however, should not be used when descaling diesel engine cooling water systems. After use of Descale Powder a 0.5% solution of Alkalinity Control in fresh water should be used for neutralisation.

Descale Powder is used for descaling of ships' boilers and marine diesel engine cooling water systems. Also, refer this link to equivalent suitable product http://rxmarine.com/descaling-liquid-20-ltr
