Suitable and very popular product for DESCALING of high and low pressure boilers, Heat EXCHANGERS etc. Its corrosion inhibitor blend PROVIDE metal protection
This is mixed with fresh water 3 to 20 percent depending on deposition of scaling. After using RXSOL-37-8865-025, Rinse all metal surfaces with 0.5 percent of RXSOL-20-2059-025 at least 2-4 house, up to neutrial of PH valve.
Procedure-of-use: 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 or sludge, then pre-cleaning with DEGREASER ( RXSOL OB 1005 ) is necessary. Depending on the extent of scaling, use a solution of 2.5-10% RXSOL-37-8865-025 . The solution will have a red colour which changes to orange when 85% of the acid has been neutralized , & to colourless when the solution is totally neutralized. Whenever possible, the solution should be heated to 60°C.Neutralised solutions can be re-activated by adding more RXSOL-54-1008-025 until the red colour reappears. This should not be done more than twice. RXSOL-37-8865-025 should not be used on Aluminium , Zinc, Tin or Galvanized surfaces.
Fields: Descaling of Boilers, Descaling of Diesel Engine Cooling Systems, Condenser, Pipeline collection system, Evaporators, Calorifiers, Heat Exchangers,The strength of the acid can be enhanced by adding 1part sodium chloride (common salt) to 20 parts of Descale Powder.If salt is not available, an acceptable alternative is to dissolve RXSOL-37-8865-025 in water. After use of RXSOL-37-8865-025 a 0.5% solution of Alkalinity Control in fresh water should be used for neutralization.
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 RXSOL-37-8865-025. 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.
